Online Geometry Tutors Who Reveal the Shape of the Universe
Your student is not bad at geometry. They were handed the one topic in math with no recipe, right after nine years of being taught to follow recipes. We give them a method for proofs — and show them why the theorems are true instead of asking them to trust it.

Meet geometry specialist and opera singer Angelique Alexander.
Career educator. M.A. in Teaching, four years of classroom algebra in Brooklyn, and an Alexander Tutoring Rocket Star since 2019.
Angelique Alexander
Angelique taught Common Core Algebra 1 at Midwood High School in Brooklyn for four years, holding 85% state exam pass rates, then at KIPP King Collegiate in San Lorenzo, where she kept over 90% passing and built a statistics curriculum around social justice. She holds an M.A. in Teaching from Relay Graduate School of Education.
Before teaching she trained as a classical singer, finishing a conservatory degree with a solo performance of over a hundred pages of memorized music. That is not a detour: geometry is the course that rewards visual and pattern thinkers, and she is the tutor who can teach the same idea two completely different ways until one of them lands.

The Alexander Difference
Passion + Purpose = Empowered
When math serves your student’s passion, it has purpose. When it has purpose, something remarkable happens — they become empowered to use education to achieve their dreams.
Personalized Matching = Student Passion
We start by learning what lights your student up — music, sports, art, science, anything. Then we match them with a tutor who shares that passion and shows them how math is the hidden engine behind the things they already love. When math serves something they care about, it stops being a chore.
“His high school teachers were great, but were not able to provide the depth and level of support that was needed… His grade went from a C- to an A- within the year he was tutoring… His confidence in math has accelerated to a point where he is planning to take a dual enrollment college calculus course next year as a senior in high school.”

Deep Understanding = Purpose
Most students survive math by memorizing formulas — until one curveball on the test sinks them. We teach the why behind every equation, deriving formulas and connecting them to the real world. When your student truly understands the math, they can solve anything a teacher throws at them.
“Tyler at Alexander Math and Physics tutoring helped my son to test into Algebra 2 honors! His math grade in school went up to an A. Then when we told him he could stop tutoring with Tyler he didn’t want to stop tutoring because he enjoyed what he was learning.”

Confidence First = Empowers Students
There’s no such thing as being ‘bad at math’ — only bad math experiences. A harsh teacher, embarrassment in class, one bad test — and suddenly your student decides they can’t do it. We rewrite that story. With a supportive tutor who believes in them, ‘I can’t’ becomes ‘I’ve got this.’
“Being a straight A student, it was difficult to accept her lower grades and it affected her confidence… within two sessions, my daughter felt more confident in Algebra, her test scores improved… My daughter had not only improved her grades but also developed a genuine interest in math.”

Everything changed for these families.
My 14 yr old daughter took a month of weekly sessions to help prepare her for 9th grade geometry. She gained a lot from personal and targeted tutoring with Rebecca and as a parent I greatly appreciated the flexibility and timely and clear comms on setting up sessions, scheduling and pricing.
My daughter has been struggling with geometry in high school. We signed up with Alexander Tutoring and she has been working with Gerald. A friend of hers in the same class signed up first and told her, with great enthusiasm, "you HAVE to get Gerald!" My daughter enjoys the tutoring sessions and reports that Gerald is able to explain concepts to her in ways that she understands, and that he also has a sense of humor, which she appreciates. There is zero foot dragging or complaining before her tutoring appointments. My only regret is that we got her started in the spring, when she was already having a lot of trouble, instead of getting ahead of the problem earlier. Her grades are up and her overall attitude about math is much improved. Thanks Gerald!
Gerald has been amazing for my son to work with. He is always on time, courteous and ready to support my son in his challenges with Geometry. He does homework review and test prep during his sessions with my son and it has been very helpful in all of us getting through the school year. Thank you, Gerald... you are appreciated!
We are incredibly grateful for the support, patience, and encouragement provided this semester. What started as a stressful and discouraging experience has completely turned around, not just academically, but emotionally as well. Beyond helping strengthen understanding and confidence in Geometry, the consistent positivity, calm approach, and ability to connect have made such a meaningful impact. Seeing renewed confidence, reduced anxiety around math, and even excitement after assessments has been wonderful to witness as a parent. Krishaan, thank you for not only being an excellent tutor, but also for being someone who truly knows how to motivate and support students through challenges. Your work genuinely makes a difference.
I actually had a few conversation with Sean before I enrolled my son into their programs. Sean was very patient and understood my concern. He assigned my son with Jonathan to do a one on one Geometry session in summer. My son usually gets bored easily and it's hard to capture his full attention. Jonathan did a fantastic job to attract his attention and able to challenge him plus boosting his confidence. My son was very happy with Jonathan. Our goal is to help him to get a solid foundation in summer so that he can master his honor class in fall plus the upcoming pre-cal class. The amount of homework was just right so that he spends reasonable amount of time in playing and working in summer. I strongly recommend Sean and Jonathan for Maths advancement.
We have been very happy with the tutoring our daughter has received from Felix who is one of their tutors. He is patient, smart and caring. Our daughter enjoys seeing him and always comes out of the sessions feeling upbeat. Felix takes the time to send us detailed emails about her progress and what they have been working on. Sean has been wonderful to work with, helpful with scheduling and increasing number of sessions when needed. Our daughter was struggling in Geometry and ended the semester with a B.
Sean is wonderful, he is able to communicate in such a way that our son gets it the first time around. I found Sean about 2 years ago when my husband and I struggled to understand Common Core as our son was having great difficulties understanding it. Sean did amazing work in getting our son to understand Common Core and soon our son was getting A's in Algebra. Last year, we returned to Sean to help prep for the High School Placement Test (HSPT) required as part of the admission into catholic high school. Sean not only successfully prepared our son for the HSPT, but also gave advice on taking the timed exam. This year, we returned to Sean as our son needed a little help in Geometry and Physics - Sean is simply a rock star! Thank you Sean for your effective communications and tutoring skills!
Sean worked with my 9th grade daughter this year and helped her achieve good performance in both Physics and Geometry/Math. He was flexible and easy to work with and my daughter gained confidence and improved her grades consistently over the school term.
My daughter has had a wonderful experience with James and Caleb, working on deductive geometry and algebra 2. Highly recommended.
Our son took some very challenging math and physics classes, with a mixed bag of teacher quality and support at his public high school....some teachers, were beyond outstanding, and some not very good at all. Understanding how important a solid grasp in math and physics would be, given our son's interest in engineering at the time, we decided to find a tutor that could support him along the way. We wanted to ensure he wouldn't suddenly fall behind and unravel his strong efforts to learn the material at school. Luckily, we found Alexander Tutoring. Sean Alexander was compiling a stellar team of tutors, carefully vetting each one. As a freshman in high school, our son was tutored by Nikki, who did a fantastic job supporting him through Geometry. Due to a scheduling conflict after that, our son was paired with Wilder, who tutored him for the remaining 3 years of high school math and physics. Over that time he took all of the highest level AP calculus, AP statistics, and AP physics classes and met with Wilder once a week.I can't thank Sean and Wilder enough for the exceptional experience and support our son received those last few years. Week after week, he looked forward to his tutoring sessions with Wilder, delving into particularly vexing problems that he could not work out on his own. Wilder's expertise was truly impressive, and his teaching approach was fantastic, not only shedding light on those confounding problems but also inspiring our son to continually learn more. That inspiration to elevate his understanding further, ultimately lead our son to a free MIT online program (not for credit, just to learn). The MIT test he took, indicated that his knowledge of the material was exceptionally high. He also received 5s on every AP calculus, statistics, and physics exam he took and performed very well on his university math and physics entrance exams where he tested into honors physics and an equally high level of math. Although our son is no longer terribly interested in engineering, he is still passionately interested in math and physics and I feel pretty confident that those subjects will play an important role in his future career. I can definitely thank Wilder and Alexander Tutoring for helping to develop and nurture our son's interest in those subjects. Rather than having a stressful experience with math and physics in high school, he grew to love them and now studies them simply because they are intellectually stimulating and "fun".
We have lived in San Francisco for 14 years and my 3 children have attended public school. MOST of the time they have enjoyed great or fine teachers. When my daughter got to high school, the math teacher she had for Algebra 1 was not good. My daughter is curious and works hard. Math is not her favorite subject but she worked hard and still could not understand and got D & grades. As a parent, I’m not as concerned about grades. I want to know my children are making the effort they are capable of most of the time, showing up and trying. I also want them to learn and understand. Much of my high school math career was a total waste and I learned very little. If you don’t learn Algebra 1, it’s a hot mess as you don’t have the necessary foundation and once in calculus, if you make it that far, most mistakes are algebraic according to a principal we had with a PHD in Math. My daughter got another terrible teacher for Geometry. Even the school counselors would speak openly about this teacher being one of the worst in the School’s history. My daughter was trying hard and yet not understanding and getting terrible grades. After studying really hard for a test and feeling confident she understood, I remember watching her face fall one Saturday night as she checked her test grade and got a D. As a parent I didn’t know what to do Because we were watching Khan Academy videos and she was studying and still not understanding. My friend Laura told me about Sean Alexander tutoring and my daughter started with Olivia a few years ago. Immediate improvement in understanding and therefore grades. We had such a good experience with Olivia and Sean that we signed both of our teens up for the math intensive program in the summer of 2018. My kids went once a week with a tutor named Charlie to learn about algebra one and really focus on algebra basics. My daughter ended up getting a 700 on the Math portion of the SAT. She did take practice test and she did the tutoring with Alexander tutoring. She did not do any other test prep. She couldn’t believe she did better on the math portion than the language portion as she loves History and English. Our son was starting high school last fall and after his sisters experience with the math teachers, we wanted to get ahead of the issue and so he took the math intensive program just like his sister. Our son, like many do, struggles with focus and impulse control and I told this to Sean. Doing the summer intensive program relieved so much stress to the entire school year. We didn’t even do the tutoring during the school year. We tried to save money by doing online tutoring from Growing Stars (I think that is the name) and my kids thought it was boring and dreaded it and told me they really didn’t need the tutoring because what they had learned in the summer was caring them through in their classes. They both did fine all year. If you do you want to do the tutoring in the school year , I would sign up now and early because it does fill up. We took a risk and didn’t sign up because my kids felt confident they were going to be OK and they were. This summer my son, who will be a sophomore fall 2019, is meeting twice weekly with Felix. On Tuesday they meet at the library for physics and Thursday at the library for Geometry. I have learned that engaging your kids in the summer a little bit pays off a huge amount during the school year. My children do really well with the one on one tutoring and we have found it is a great investment. It’s not cheap because these are knowledgeable tutors and they have to pay SF rent too! We haven’t done any other test prep (because the free one at the high school for a day) and my daughter is doing really well on her ACT and SAT math scores but more importantly to me, she understands math! She is willing to sit and do all the practice tests on her own because math doesn’t intimidate her anymore. Like all of the tutors, Felix is exceptionally organized
James has been helping my daughter with Algebra and Geometry for a couple of years now. She is grateful to him and wishes he were her classroom teacher. We feel lucky to have his help. THANK YOU JAMES!
My daughter was struggling with math classes during remote learning last year and we started with Alexander Tutoring. They were invested in finding a tutor she liked and we tried two (she said they both seemed good). Although my daughter is not enthusiastic about math yet she did improve her grade and received an A in Geometry for spring semester which was a happy surprise for her and helped build her confidence.
Darren has really helped out our daughter with honors geometry this semester. The great thing about Darren is, as hard as the problems are, he knows how to do them, and he takes the time and has the ability to explain them to our daughter so that she really understands. We are definitely planning to have our daughter work with Darren again next year.
My daughter has been studying with Alexander Mathematics and Physics Tutoring since her Freshman year in High School, taking Algebra 2H. She has been working with Felix regularly during the past 2 school years. She is currently ending her Sophomore year and Felix works with her on her Geometry H & Chemistry H classes. She has also prepared for upcoming Math during the summer with Alexander (who is also excellent), and will be doing summer prep sessions again this summer. I consider Alexander Tutoring to be an essential part of our daughter’s academic success. She looks forward to and enjoys her tutoring sessions. She feels more confident as she approaches her work (in Math & Science) and takes comfort in knowing that if there is content that is more challenging or difficult to understand, she will have the opportunity to cover it with Felix. Scheduling is also very convenient online, and there are opportunities to add more sessions preparing for Finals. What I am most pleased with is that my daughter has a positive perception and relationship with Math & Science! She knows she can have success and that these subjects can be challenging but enjoyable. My daughter and I are truly grateful to Alexander Mathematics and Physics Tutoring. Looking forward to working on Precalculus and Physics next year.

Why proofs break good students
Proofs are the most hated topic in math, and your student struggling with them is not a failing. Every year until now, math meant steps: do this, then this, get the answer. Then geometry arrives and asks them to build an argument out of nothing.
So we give them a path. We teach a proven step method for proofs, and we go back to what the rules mean. Almost every student knows pi is 3.14. Almost none know it is how many times a circle’s diameter fits around the outside. We derive the Pythagorean theorem rather than memorizing it, and we derive the area of a circle from triangles and limits.
Geometry also rewards a different kind of thinker. It is visual where algebra is linear, so the student who slogged through last year often comes alive here — and the sines and cosines introduced this year quietly decide how calculus goes later.
What Our Geometry Tutors Cover
Geometry is the first course where students are asked to prove something rather than compute it, and that shift catches strong algebra students off guard. We teach proof as reasoning you can follow, not a format to memorize.

Geometry Tutoring FAQ
How much does geometry tutoring cost?
Geometry tutoring is part of our monthly plans. Dedicated Tutor is $895/month: a weekly one-on-one session, nightly office hours for homework help, monthly progress reports and direct tutor access between sessions. The Rocket Star Track adds a second weekly session for $1,745/month. No signup fee, no contract, cancel anytime. See all plans.
Which geometry courses do you tutor?
Geometry, Honors Geometry, Integrated Math I and II and college geometry. Your tutor works from your student’s actual course, teacher and test calendar.
How do you teach proofs?
With a step method your student can follow every time, and by going back to what each rule means. We derive the theorems rather than ask students to memorize them, so a proof becomes an argument they understand instead of a format to copy.
My student was good at algebra but struggles with geometry. Why?
Geometry is the first course with no recipe. After years of following steps, students are asked to build an argument, and that shift catches strong algebra students off guard. It is visual where algebra is linear, so the right approach often makes it click quickly.
Does geometry matter for later math?
Yes. The right-triangle trigonometry introduced in geometry carries into pre-calculus and calculus, and geometry appears on the SAT and ACT. See pre-calculus tutoring.
How do online lessons work?
Your student and tutor work one-on-one on a shared digital whiteboard, and the tutor writes the math in real time with a tablet and stylus. Lessons follow your student’s class, homework and upcoming tests, and every session builds on a written plan from the first lesson.
Who are your geometry tutors?
Mathematicians, physicists, engineers and former classroom teachers with degrees in their field, never college students, including Angelique Alexander, who holds an M.A. in Teaching and taught high school math in New York and the Bay Area. Every tutor is ranked nightly on our Rocket Star Rank, so your student is matched with tutors who have already proven it. You can meet the team before you book.
What if tutoring doesn’t work?
Dedicated Tutor and Rocket Star Track plans are backed by our Full Semester Guarantee: if you’re not satisfied at the end of the term, we refund every penny. Your first lesson is risk-free, so you can see how it works before you commit.
