Experience
I am a highly experienced math and physics tutor with over twenty years of one-on-one tutoring experience across high school, undergraduate, and advanced college-level coursework. I hold a BA in Physics and a PhD in Biophysics, and I bring a deep, conceptual understanding of physics that has been shaped by ten years of teaching at the college level. My background allows me to connect abstract theory to practical problem-solving, helping students build both confidence and mastery. I have a strong record of student success, including improved grades, exam performance, and long-term retention of core concepts. A central part of my approach is the development of clear, structured study aids—step-by-step problem frameworks, conceptual summaries, and customized learning materials—that make even challenging topics accessible and manageable. My goal is not just to help students succeed in the moment, but to equip them with tools and understanding they can rely on independently.
Teaching Methodology
My teaching methodology is grounded in active engagement and confidence building, particularly through guided work on challenging problems. I intentionally introduce difficult material in a supportive way, helping students confront and work through complexity rather than avoid it, because success with hard problems is one of the strongest drivers of lasting confidence. This approach is paired with carefully designed, detailed work packets that present concepts through tiers of problems with increasing levels of difficulty, allowing students to progress at a pace that is both challenging and achievable. At every stage, my teaching is centered on the individual student and adapts organically to their needs, goals, and learning style. Over years of experience, I have developed a strong ability to recognize how different students process information—whether visually, analytically, intuitively, or through repetition—and to adjust my explanations and strategies accordingly. This adaptability is one of my most significant learned strengths, rooted in a deep sense of empathy and compassion for anyone learning a new subject. I am especially mindful of the anxiety that often accompanies math and physics, and I work to create an environment where students feel understood, supported, and capable of growth.
Why Choose Trevor?
With over twenty years of tutoring experience, advanced degrees in physics and biophysics, and ten years of college-level teaching, I bring exceptional subject mastery paired with a highly individualized, student-centered approach. I specialize in building confidence by engaging students with challenging problems in a structured, supportive way, using clear study materials and tiered problem sets that develop understanding step by step. What sets me apart is my ability to adapt naturally to different learning styles, guided by empathy and compassion for the challenges of learning math and physics, helping students move beyond anxiety to achieve lasting understanding, measurable improvement, and genuine confidence.

Other Interests
I have a deep love for the outdoors and the natural world, and I especially enjoy gardening as a way to stay connected to nature and the rhythms of the seasons. I’m an avid reader of science fiction, drawn to its imaginative exploration of ideas, and I also have a strong interest in history and geography, which satisfy my curiosity about how places, cultures, and events shape our world. In my free time, I’m particularly passionate about modern board games that immerse players in diverse themes, offering creative, strategic, and social ways to experience new perspectives.

I highly respect Tasha and definitely ask her for feedback & teaching suggestions often because I fully trust her. Also, she speaks Spanish! She is extremely intelligent and some day she's going to be one of the most successful teachers in her district. Thank you for everything you do for our children. We couldn't be more grateful.

Very knowledgeable of a multitude of math subjects and is pretty much always available! Has helped me pass all my college math courses! Lifesaver! He's also a really great guy! Highly recommend him and this company! Great all around!

It was a hectic Sunday, and my son was struggling with coding which is a language I am not familiar with. I luckily stumbled on TutorNerds and Adam was able to connect us with a fantastic teacher. I cannot express my gratitude enough for Mark for his exceptional skills and extraordinary care for my son. I have never seen my son so elevated after a tutorial. I am glad I stumbled upon this place and look forward to using them for many more years! Thank you, Adam and Mark, for making a difference! You guys are amazing! If you are looking for a tutor, I HIGHLY recommend trying TutorNerds, from my experience so far this place is a gem!

Getting my child help with her school work was a real struggle for me. Having a tutor that I could rely on was the biggest difference. We are so happy with Janelle from TutorNerds. They are highly recommended for any little ones that need some extra help.

Calculus Science Tutoring Biology

I am very impress so far with TutorNerds. Brandy was very helpful and responsive when I was first asking questions about the services TutorNerds had to offer. She was able to pair my son with Sydney who is incredibly sweet, friendly and patient. She is helping my son who just started the 7th grade with homework help and building his confidence. My family was so happy with their services that my nephew has started tutoring with Sydney as well. I would 100% recommend TutorNerds.

Physics

There are no words to express how thankful I am for TutorNerds! I called them last semester when I was panicking over my "F" in my intro to symbolic logic college course. Thankfully, they were able to send Brandy over as my tutor. We worked diligently for two months, and I mastered a course I never thought I stood a chance in.

Chemistry English Tutoring

I was recommended here by a class mate, and I'm so glad I followed through. I was struggling to keep up with the material in class and I knew I needed some extra one on one time to really understand the material. Ramin has been so helpful with each chapter and going over the practice midterm. I went from getting C's on test to A's. I highly recommend this as an investment into yourself and your education, versus failing classes. He is patient but will also push you to do better every time! Thank you Ramin!

TutorNerds is an amazing tutoring service! I can't speak highly enough about them. Farzan has been an incredible help to my daughter in math and science. He is able to explain things in a way that she understands and is so patient, friendly and kind. It has made such a difference for her and he always makes time when she needs help. We appreciate him so much and highly recommend Tutor Nerds for their exceptional tutoring and customer service.

Tutor Nerds are the BEST!! I was desperate to find someone to help me with my college Statistics class, so at the suggestion of a friend I contacted Adam at Tutor Nerds. The demand is high at this time of year for tutoring assistance since the semester is coming to an end, but Adam was quick to find an appropriate tutor for me. Steven was helpful for one session but was unable to continue due to his own studies. Adam B. was then scheduled to meet with me. He is SO smart, and kind, and patient and was actually able to help me understand this very complex subject. I passed the class! THANKS, Tutor Nerds. I'm getting closer to my goal of obtaining my BS degree in nursing. I HIGHLY recommend Tutor Nerds and will happily give their name as a referral to friends and colleagues who need assistance with their studies--specifically statistics.

If you are doubting about getting a tutor with Tutornerds do not hesitate any longer and go for it! I can honestly say that my experience overall with this amazing company and amazing tutor Andrew has been 10 out of 10. Andrew is a great teacher and he is pretty much a human calculator. I am so happy....I am right on track to receive the grade I really wanted in my College Algebra/Pre Calculus class. Tutornerds has helped me learn the material, finish all of my homework and prepare for the exams. My GPA is going to be where it needs to be and I am so thankful.
