I love teaching and look forward to sharing and promoting the fascination and wonder of the sciences with young minds everywhere, one student at a time, and have thoroughly enjoyed spending hundreds of hours discussing science with both teens and adults through WyzAnt. Teaching is second nature for me, growing up in a family where both parents were high school teachers. My father taught Biology for 30 years, which helped fuel my passion and enthusiasm for the sciences and motivated my pathway...
David really helped me prepare for my test this week. I did not understand the Hardy-Weinberg Principle when my classroom teacher explained it. David made it easy for me to understand not only the law itself, but how to use the equations. This lesson was my first with David, but he worked with my sister several years ago so I already knew he would be a great tutor! I highly recommend David to other biology students.

My daughter was thoroughly impressed on how clear and concise you were. Thank you for an amazing tutoring session.

David worked with my daughter weekly during the months leading up to her AP Bio exam. She felt like the material was very challenging, but David was very patient and gave thorough explanations during reviews. He used many helpful diagrams and practice problems to help her completely understand the concepts. He was able to break down complex concepts into easier ways to understand them. My daughter felt like she felt completely prepared for the AP exam thanks to the excellent guidance and teaching of David. Definitely recommend his help for this course!

David is an excellent tutor with a true passion to help students succeed. He taught my daughter AP Biology and made this difficult subject interesting. David uses drawings and analogies to present the materials and makes the content much more relatable and easier to digest. There were a few times when I needed to reschedule or squeeze in an extra review at the last minute before a big test, David kindly accommodated. David has the friendliest and most supportive attitude and makes every lesson not only helpful, but enjoyable. David made my daughter realize it?s perfectly ok to get extra help when she needed it, while past tutoring experiences have left her feeling more stressed and less prepared.

David used very effective teaching aids and is committed to the student?s success. He taught two of our students AP Bio. Our student went from struggling to having an A in Biology. Our only regret was not enrolling with David sooner. It there were more stars available, I would stand in line to give it!
- Nike A. from Allen, TX
I struggled a lot in AP Biology, and David was great at breaking things down and was very patient when teaching me concepts. We also went through FRQs and practice questions, which he broke down. Those were very helpful. He also helped me prepare for the SAT subject biology test recently, which (hopefully) I did good on! I scored a 5 on the AP exam last May. Highly recommend!

Is David the right tutor for you or your child? You will find nobody better. My daughter is only sorry about one thing after working with David: that her biology lessons with him can't continue for the rest of her academic career. Sometimes teachers are good, and you are grateful in the moment for their help. David was fantastic, and we will be grateful for the rest of our lives. David helped make my daughter's life-long dream of going to vet school become a reality. She is a high school senior living in Europe who applied to a European vet school that accepts highly qualified high school seniors upon graduation-- ?if they pass the biology and chemistry entrance exam. Because of poor instruction at her school, however, and later because of the pandemic, my daughter had barely learned any biology at all by the end of December. We expected her vet school entrance exam to happen in February. That gave her just a little over two months to choke down every chapter of the prevailing college biology textbook and know it backwards and forwards. In a panic, we turned to David. He worked four times per week with my daughter, covering an enormous amount of material with her, making it all easily understandable and graspable, in record time. (The textbook is about 1500 pages of small print text. They covered most of it in two months.) Not only did David make time four times per week every week for my daughter and accommodate her ever-fluctuating schedule, but he also on a dime dropped topics, skipped forward or backward, or moved to entirely new biology topics, depending on my daughter's needs. He was always ready. He was always prepared. He never missed. He was never late. He never let us down. He knew the biology inside and out and helped my daughter learn it, too. And he never seemed to need preparation time. He knows the biology just that well. David has the teacher "thing", the magic that lets him turn difficult, complex material into something simple to learn. And the best part about David, he's completely approachable, friendly and nice. Even the shyest or intimidated student will warm to him. My daughter passed the vet school entrance exam with flying colors. She still has to take the Biology AP exam in another month or so, but she's totally ready, thanks to David.

Both my kids got A grades for their dirt semester this year! Thank you Mr David. Mr David is a great teacher. He is very easy to work with, very kind and always smiling. He taught my son Anatomy last year and Avi got an A in the class. This year he will be teaching Ashika Biology and Avinash AP Biology. He uses visual aides to teach the kids and is very thorough. He also works well and ahead of time with the curriculum .He makes them understand the topics with ease. I recommend him for anyone who is looking for a Bio tutor who can bring the best out of you without any stress.
- Avinash S. from Milpitas, CA
David has been absolutely amazing in supporting my daughter through her AP Biology class. I don?t know where she'd be without his help. He is kind, patient, caring, goes above and beyond to make sure she understands and is successful. We can feel David is invested in her success in this class. He makes the material manageable and easy to understand. I could not recommend David more and am so grateful we found him.
- Jill S. from Los Altos, CA
My daughter really appreciated David's teaching style and patience in explaining concepts. He also sent graphics that explained the concepts. She accomplished a lot in an hour with David and walked away feeling more confident in the subject. Would definitely recommend David to others seeking tutoring in AP Bio.

David has taught 4 API Biology classes for my son. He has given a good conceptual understanding of the subject matter so far. David is also very diligent about sending notes of what he has taught every class. I will be providing another review after my son has more classes with David.
- Govind D. from Farmington, CT
My daughter was struggling to follow lessons in her AP Biology class so we scheduled lessons for her with David, and he was great! He was an amazing tutor in that he helped my daughter understand concepts very well and was extremely patient. His pictures and diagrams were also greatly helpful! Would completely recommend as a reliable tutor!
