Hi! I would like to help you to reach your academic and professional goals. My experience has demonstrated an ability to help a good student to become better and to rescue a challenged student to achieve his/her potential. I retired after two decades of research in the biotechnology industry and taught at the university level for several years. My career has focused primarily on the sciences, particularly chemistry, biology, biochemistry, physiology, molecular biology and genetics. I have also effectively taught and tutored various pre-calculus mathematics courses, such as pre-algebra, algebra, geometry and trigonometry. I enjoy assisting students to master concepts in coursework, to understand theory and interpret results of laboratory exercises, and to prepare for local and national exams.

David was great! I was able to make an appointment with him for my daughter on VERY short notice. He arrived on time and was very knowledgeable. He made sure that my daughter understood everything that he was explaining. If she or I had any questions he was able to answer and explain. I sat in because the last tutor she had taught her everything wrong and most of the time when she had a question...the tutor didn't have an answer. David didn't have a problem with me sitting in or asking any questions. We will definitely be contacting him again!
Thanks for your kind comments! I enjoy helping people to understand challenging concepts and I enjoyed meeting your family!
David helped me review content for my upcoming MCAT. He was helpful and did a good job of dumbing down a lot of concepts.
David was very personable and appears to have a good spirit about him. Will keep you posted on future meetings.
I've had 2 2-hour sessions with David and my confidence in myself has doubled. He's a brilliant man and is great at dealing with not so brilliant students like me. So happy I have him in my corner. I highly recommend his services to anyone afraid of math or science. Thanks David!
Simply put, David is one of the best tutors that I've ever had. David is very understanding of one's innate abilities on said topic matter and does not judge, rather he seeks to aid and inform as any tutor should. Even after explaining a complex AP Biology concept to me for 10+ minutes, David is very understanding when I simply have no idea what is going on and is never hesitant to re-explain the concept. Moreover, David is always extremely flexible with times. Unfortunately, there have been times where I have had to cancel my tutoring session the hour before it was scheduled to occur, while I do not endorse this practice, David was always very flexible and understanding of my situation. Furthermore, David is very caring and passionate. He truly does care for my studies in AP Biology, and he truly does want me to succeed.
Thank you for all your help David!
Resistant to getting a chemistry tutor due to my own qualified background in chemical engineering and nursing, I finally realized a disinterested third party would have more patience than me. David was professional and patient every session. We have used his services three times a week for a couple of months now and have been consistently pleased with every session. My son has verbalized appreciation for having David tutor him, says that he explains things in a way he can understand and at a pace wherein he can absorb the information. I highly recommend this tutor for math and the sciences.
David was very patient with my daughter. We didn't use him for a great length of time, but the time spent my daughter said he took things at a perfect pace.
We used him at the beginning of the school year, she was feeling like she couldn't follow in class quick enough and he brought her up to speed. Her grades have improved in the short time spent with him and she gained some confidence to go it alone and is doing great. Thanks David!
Over the summer Mr. J tutored my daughter in Math to get her ready for high school Algebra. (Her eighth grade pre-algebra teacher was such an epic failure.) Mr. J has a solid understanding of both math and science, and is incredibly clear in conveying the most complex of concepts. He even gave my daughter a glimpse of geometry, trigonometry, and physics. My daughter is more confident going into the new school year thanks to him!
Our son was really struggling in his high school Chemistry class. Because he did not understand the work, he had fallen behind on assignments and done poorly on tests. He was frustrated to the point of giving up. Dave was very patient and always encouraging with our son. He was also very good at communicating with me and went out of his way to accommodate our hectic family schedule. After working with Dave, my son was able to catch up on all his assignments and prepare for his semester exam. His grade greatly improved and he got an A on his final Chemistry exam! We are so pleased with our son's progress and grateful for Dave's help! We know his tutoring made all the difference!
Tami - Thank you so much for your kind comments! I was very pleased to learn how well your son had performed on his final chemistry exam. Beyond the grade, I am suspecting that he feels much better about himself and his ability to master challenging course assignments. I sincerely hope that his positive attitude carries over into next year!
Mr. Dave J. is very knowledgeable and patient, he actually made my son smile, and my son hasn't done that for a while concerning his Chemistry class. My son is much more confident to take his semester exam now thanks to Dave! I was very impressed! Dave is Awesome!!!
David continues to be patient and knowledgeable as he works with my daughter to obtain her Honors Chemistry goals.
Thanks, Alicia, for your kind feedback! I enjoy working with your daughter - she has a great desire to learn and is highly teachable. Thank you for your great support as a parent!
I have worked with David J. for the past weeks. He is very knowledgeable on the subject matter and extremely helpful. When I have trouble understanding a concept he puts them in terms I can understand. I will continue working with him this semester.
Thanks, Peggy, for your kind feedback! You are a joy to tutor because I know that you are truly sincere and committed to master the course material. I look forward to working with you so that you can get all of that preliminary math out of your way and move ahead!
David was very proficient in the subject of chemistry and microbiology. I was able to grasp concepts within 2 hours of David's tutoring more than weeks of classroom instruction with my college professor.
In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

The Medical College Admissions Test (MCAT) is an index routinely examined by admissions panels as a standardized exam to normalize variations among undergraduate institutions in grading. My broad professional experience can supplement your personal efforts to improve your comfort level with the questions and offer a greater probability of a successful outcome. As a university professor (see personal profile), I have taught science and mathematics to undergraduate students and helped them to prepare for the MCAT and for medical school.
Physical science primarily combines general understanding of chemistry, physics and earth sciences. I have enjoyed significant opportunities to teach these materials at the university level and to tutor students in high school and in college. Appreciation of the physical sciences is useful both as an academic discipline and also to increase comprehension and common sense applications of phenomena in the world we live.
I completed my graduate studies with a major in Biological Chemistry and a minor in Physiology; I retired from the biotechnology industry and from university faculty with 20+ years of industrial research in Cellular Physiology & Biochemistry.
I lived in Brazil for five years; fluent in written and conversational Portuguese.
