Recommended by a top educational therapist, Ender has helped my child get back on track. It's a question of fit. I'm giving him 4 stars only because he's not an educational therapist, not because he's not "excellent." After four sessions with him, my child has regained confidence needed to move on to the next level. Don't trustthe b.s. negative reviews that are of one extreme or another, it usually lies somewhere in between. The teacher either has the knack...or not. Ender definitely has the knack. read more

My two sons have been going to Ender for their entire high school careers--and he is simply put, the best! I was referred to him when my son was in a crisis--literally flunking Pre-Calculus and in danger of getting an F for the semester. My son was reluctant to go to a tutor, but Ender said--"look, you will know if this is helping in just a few sessions," and he was right. We saw vast improvement after only three sessions. With Ender's guidance and explanation, my son went from an F to an A for the trimester and got a B for the semester. After that, he never wanted to head into a math final without a tune -up session from Ender. He did very well in math and AP Stat throughout the rest of his high school years. So when my younger son tested into the very rigorous Accelerated Math course his Freshman year at Lowell, I knew what to do. I had him start with Ender from the beginning and he was one of the few to emerge from that class with an "A." We also asked Ender to tutor our sons for the SAT and SATIIs and he helped them pull down a surprising 800 in the SAT II--surprising because my son doesn't think of himself as a "math student." Ender is kind, patient, rational, and as my sons say, "just a great teacher." Everyone I have ever sent to him has been very happy with the results. Some of my friends decline to go because he is not the least expenseive tutor in town, but I want to say "He is worth every penny!" So often, I've seen friends spend lots of time and frustration on a less accomplished tutor--with mediocre results. Ender delivers results. Plus, my sons really like him. He's low-key and professional, and he eases kid's fears. I cannot tell you how grateful I am to have a resource like Ender for my sons. read more

Ender was fabulous with my son Oscar. He helped him to improve his score by 10% when he took it the second time. He also lent a calculator to my son when he didn't have it with him and we still need to get that back to him! (will right after the holidays!) Thanks SF Tutors! read more

Ender is great! Math has never been an easy subject for me, I came to him with the mindset that "math is not my thing, I will never get it", Ender turned it around. He was very patient with me, guiding me through every step - so I regained my confidence. When I needed help in Chemistry, he found me a tutor! That's how caring he is. He truly cares about his students and when I needed extra classes on a short notice, he always made it work. Go to Ender, you will NOT regret it! read more

A truly exceptional math tutor. I give the highest praise to Ender for his ability to keep my son engaged, learning and ultimately excelling in his Statistics class at Lowell High School. After realizing that he was in over his head, we convinced our son that he needed a tutor. He unwillingly began to work with Ender, and after a few sessions began to request him instead of avoiding him. Ender prepped him for all his tests and his AP test, and it made a big difference. I know that Ender is a great tutor because when my son was asked if his Spanish tutor was any good, he said, "not compared to Ender." read more

Ender tutored both of my kids (one female, one male) as they were approaching the SATs. They are very different personalities, and had different aptitudes for the various areas of high school math. Nonetheless, both eagerly attended their tutoring sessions and felt much more confident in their ability to do well on standardized tests as a result of their classes with Ender. One announced, after a particularly good session, "I'm a genius today!" Ender somehow managed to make them feel that he cared about them personally and wanted them to be successful.

Amazing math teacher for a non-math student!! Ender was recommended to me by word of mouth as a high school senior (for precalc), and he is by far the best tutor I've had yet. I've been through a lot of tutors for math throughout the years, and he's the only one I've had that made me feel comfortable, and not stupid, about not understanding math in the way it was taught to everyone else. He seemed to enjoy himself, which made me enjoy going to tutoring, and he explained things in ways I could understand while actually making an effort to go over concepts multiple times without me having to ask. Unlike a lot of tutors I've had, he's very pleasant, thoughtful, and easy to be around, and doesn't make you feel inadequate for not understanding, or make you feel like an imposition when you do ask him to explain something more than once. Even though I only went once a week, we managed to cover a lot of material and even start (and sometimes finish) homework assignments for the next few days. I highly recommend Ender for tutoring in anything math related. read more

Ender Markal is an amazing teacher! He is smart, soft spoken, funny and puts his students immediately at ease. My daughter's been through several other tutoring programs that proved not only absurdly expensive but utterly ineffective for her. When we found SF Tutors and met Ender we felt our luck had changed. Ender really has a talent for explaining algebraic concepts and possesses the uncanny ability to reach through to his students so that they really understand! There should be a hundred positive reviews for SF Tutors. Really! My daughter looks forward to her tutoring sessions and is excited about a subject that used to make her anxious and frustrated. Needless to say, she's raised her math grades considerably and the confidence she's gained has been invaluable to her as she gets ready for high school. Don't short change yourself by going to other places...call Ender at SF Tutors and you'll feel like a weight's been lifted off your shoulders. Really. read more

Ender is an AMAZING calculus tutor. My daughter passed AP AB Calc as a high school senior and nailed the exam. As such she enrolled in 2nd semester college Calc as a new frosh at a top notch East Coast College. Test one = C. Test two = even worse. Tears. Panic. Thoughts of dropping the class until MOM to the RESCUE. I called a number of math tutors and explained the material that my daughter needed help with. Two of them referred me to Ender. I booked two 1.5 hour sessions during Thanksgiving break. Ender was able to quickly assess the areas my daughter needed help with. He answered her questions with simple, straightforward examples. After one session she was smiling. After two sessions she was confident to the point of being giddy. The next week my daughter took her third midterm and earned a 91% which due to the curve was a straight A. She recently took her final and feels like she hit it out of the park. Ender is not cheap but he is worth every penny. I have recommended him to all my friends. Don't hesitate to use SF Tutors. read more

Ender Markal is by far the most awesome math tutor on the planet. He has a special way of teaching difficult math to kids. I used him for both my boys in prep for the SAT's and also the Subject II Math tests and they did incredibly well with his help scoring in the high 700's. He is kind, patient and a true genius in his field. He is very professional and accommodating. I have recommended him to many of my friends and they have been equally impressed. You will find no better math tutor out there than Ender. read more

After transferring high schools, I found that I was extremely behind in the math class I got placed in at my new school. Ender had tutored my three older sisters when they were in high school and helped them throughout many different levels of math. Ender taught me much more than the step to step procedures to solve problems. He's taught me how to actually UNDERSTAND the math that I am doing. He explains it in a way that is easy to understand and make's the math seem a lot less intimidating. Ender has helped me so much throughout the different levels of math in high school and I would recommend him to anyone! read more

Ender helped me so much with AP calculus AB. He explained problems in a more practical way than my teacher and was an excellent supplement to simply learning concepts in class. He really teaches you how to do problems. I went from getting a c on my first test (before i started getting tutored) to averaging 98%! He's a great confidence booster and a patient teacher. I highly reccomend him. read more

Ender is Awesome! My son was struggling his Freshman year of high school in math and we realized it was time to seek out a tutor. While I generally prefer a "word of mouth" recommendation, I decided to check out tutors on line and Ender's bio resonated with me. I called him and we set up a session. He and my son immediately clicked and I saw my son's math confidence soar. My son is now a junior and continues to work with Ender and will look forward to guidance as he starts preparing for the SAT. Ender is a kind and patient and wants his students to be successful. You know he is doing something right, when your child looks forward to going to his tutor! read more

Ender is a great tutor. First, he is a excellent teacher and is very effective at explaining math concepts. Second, he knows the high school math curriculum and what to focus on. Third, his warm and engaging manner make him fun to work with. He has a wonderful rapport with my daughter who actually enjoys her math tutoring sessions. I would highly recommend Ender to anyone. read more

I went to Ender to review math concepts before taking the SAT. He really helped me build confidence in math and has a true knack for explaining things. He worked one on one with me and focused on my weaker sections, explaining everything clearly. It was great to have found him, he really helped me and I have a firmer foundation of math abilities now. read more

Rude over the phone, refused to provide rates or other relevant information. Can't speak to the actual tutoring, as I was essentially turned away over the phone. read more

I have always had a really difficult time learning math. I struggled so much in high school I just stopped taking math all together after advanced algebra. I tried taking AP stats and dropped after two weeks. Now I'm taking statistics at CCSF to be eligible to transfer to a UC. I would be just as lost as I was two years ago if it weren't for Ender. Ender has been extremely helpful. Not only is he patient and kind, he will help you reach your goal. I went to him after getting a C- on my first stats test. After one visit, on the next exam I scored a 90% on the curve. The test after that, 100%. I currently have a 97% in the class, something I never thought I could do. Ender's results speak for themselves. He is worth every penny as long as you put the work in, He won't do it for you, but he will help you help yourself more than any other tutor I've had in my life. Ender is expensive but definitely worth every penny. With Ender there's no need to worry, just do your best and you will Succeed with his help! read more

After working with Ender Markal for three years, while in three different math classes(Algebra, Geometry and Statistics), I can confidently say that he was one of, if not the most helpful math tutor I have ever worked with (and this is coming from someone who has had many). He is patient and kind. His instructions are clear, and he creates an environment where learning and understanding are the top priorities. I always felt comfortable and encouraged to ask questions, to receive another example, or to have something explained in a different way. He helped me feel infinitely more confident and ready to participate every day that I went to math class. When helping me prepare for tests, he was not only present during our time in person, but encouraged me to send him any last minute questions I had while studying independently. Overall, I had an amazing time working with Ender Markel. I genuinely hope that students in need will reach out to him for help. read more

Ender is very patient and nice, and explains everything clearly and slowly in ways that are easy to understand. At the time I went to him for tutoring, I had a D in geometry and managed to pull it up to a C+ with the next test. I also went to him to prepare for the SAT, and he not only reviewed the math section with me, but also went over ways to score well on the test as a whole. He is a great teacher and makes his sessions interesting and fun. read more

My daughter goes to a well known private school in San Francisco, and needed to get her math SAT scores up by 10% in order to be competitive in the college process. It's difficult to do that on your own, and since schools don't teach to the test, this seemed a reach goal. Luckily for us, Ender made it happen. He's an excellent, straight forward, results oriented tutor. He does problem solving and focuses on getting as many of the likely problems in front of the kids as possible, along with strategies to attack those problems. There are many tutors out there (including some we tried), who focus on the 'softer skills' like nutrition, meditation, good sleep etc. My daughter didn't need that; what she needed was to do the problem sets with a tutor who is patient and clear enough to walk her through each one. She thought Ender was incredibly helpful, and she came home from her tutoring sessions feeling empowered and accomplished. We can't recommend him highly enough. and yes she got that 10% boost. read more

My daughter just passed the CHSPE!!! And without Enders' help this would not of occured.Quick history...VERY bright daughter loved school ...then her father got ill, she was 14 and didn't want to sleep , didn't want to leave the house. She was getting sick (colds, cramps, headaches) and high school was the LAST THING on her mind..don't think I just gave up, there where doctors, shrinks, teachers, more doctors then a caring truant officer came into our lives and taking her out of high school;( her 3rd one) was the answer...Then came the CHSPE, she did great on the English but not good in Math. Wat was I to do it's not like I could get her teachers to help; she didn't have any. And Lord knows I couldn't do it... but Ender did.His Compassion ablty to get to the heart of what she needed saved my daughters confidence and SHE PASSED!! Just walking into his office I could feel the air of calm, then when I finally met him face to face I got my faith back I truly felt that this was the guy who was going to give her the CORRECT TOOLS at THE CORRECT TIME...AND HE DID !!! I could never thank him enough. You will not be sorry putting your child in his hands. read more
