David Porter gives students the leverage they need to succeed

What Parents and Students Say about David Porter's Leverage Tutoring

WHAT PARENTS SAY
Chemistry Tutoring
"David tutored my daughter in chemistry in 2001. Her chemistry teacher didn’t teach in a way that worked for her so I hired David to get her through the first semester. David acted as her only real chemistry instructor. When I was able to transfer my daughter to another class for the second semester she ended up doing great by the end of the year. She will be graduating this June from U.C. Davis with a degree in chemistry. She has received a Rackham Merit Fellowship to pursue graduate studies in inorganic chemistry at University of Michigan. We will remember David for getting our daughter through that rough time. She could have come away from her high school chemistry experience with no intention of ever cracking a chemistry book again, but now it's her passion. David made a real difference in a short time." Thank you, David! Marin parent
 
"It’s been many years since Mr. Porter worked with our son on Chemistry and Algebra II. He is doing so well, thanks in large part to Mr. Porter. Without his help, our son could not have done nearly as well as he did in chemistry. Mr. Porter’s command of the subject, together with his patient and steady style made all the difference for him. Our son went on to earn a degree in Biochemistry from U.C. Davis. While he was there, he received the Chancellor’s Award for his research in biochemistry. Following graduation from college, our son landed a good job at Bio Marin, the pharmaceutical company. He is now attending graduate school at San Francisco State University in order to get a Masters in Biochemistry. Thank you David, and all the best." Novato Parent

MATH TUTORING
"Our son’s confidence increased due to David’s support and clear instruction". Parent of a Marin Algebra II student
 
"I was more proud of our son for passing Algebra II with a solid C than I was for the A’s he got in other courses because I know how hard he had to work to make that grade. Mr. Porter’s work with him made a critical difference." Marin parent
 
"Our family is very pleased with the quality of instruction David provided for our daughter.  He explained very complex concepts in a manner that helped her understand. Also, she learned the value of proper study skills in math through David's work with her. Our daughter found her confidence again in math and now again enjoys it." Parent of a Novato Algebra II student
 
"David is a gifted teacher & tutor. My 17 year old son has become a much stronger student with David's help. They work on Algebra II & Chemistry. My son's grades have improved, and he feels more confidant in class, and that makes him feel great! Wish we had found David sooner!" Novato parent.
