I haven't always wanted to be a teacher. I went to graduate school in Chemical Engineering and I was asked to teach classes in Fluid Mechanics, Thermodynamics and Mathematical Modelling. It was here that I fell in love with teaching. Helping others to master challenging topics is such a rewarding endeavor.

I haven't always wanted to be a teacher. I went to graduate school in Chemical Engineering and I was asked to teach classes in Fluid Mechanics, Thermodynamics and Mathematical Modelling. It was here that I fell in love with teaching. Helping others to master challenging topics is such a rewarding endeavor.

I've devoted the better part of my life to teaching because I love the profession. I've worked with students of all ages (elementary school through adult) and all ability levels. I am experienced at preparing students for standardized tests such as the SAT (Math, Chemistry and Biology), AP (Chemistry and Biology), ACS Chemistry Olympiad and the MCAT. Many of my students earn scores of 5 on the AP Exam and/or 800 on the SAT Subject test. I have been recognized by MIT (4 times) for being the most influential high school teacher of one of their
incoming freshman.

Although I love science, I have always been a bit of a math nerd (790 Math SAT, 800 Math GRE). I have had many years teaching math to students from elementary school through adult. I can help with such topics as fractions, percents, exponents, volume and area, graphing, factoring, linear equations, quadratic equations, inequalities, polynomials, trigonometric functions and identities, probability, matrices, exponential and logarithmic functions, and many more topics.

Chemistry can be a very challenging subject if you don't have the proper problem-solving skills. I can show you a technique that makes the solutions just fall into place. I can help with naming chemical formulas, balancing equations, stoichiometry, thermodynamics, solution chemistry, colligative properties, acid/base chemistry, oxidation/reduction, chemical kinetics and many more topics.

Biology is such a difficult subject because of the wealth of information that you are required to learn. The complexities of cellular respiration or mitosis/meiosis are hard to keep straight. My 4 years at Johns Hopkins University and my years of teaching biology have given me a strong background in this area. I can help with cell biology, molecular biology, genetics, ecology, anatomy and physiology, and biochemistry.

Are you having difficulty in math or science class? Let me help you or your child succeed. Each student learns concepts in their own unique way and I can tailor my lessons to suit your specific needs. Schools are placing more and more emphasis on math and science and you don't want to be left behind.

A “true” teacher

We had Bill for two sessions to guide my daughter on her upcoming SAT2 Chemistry practice test that was given as mid-term in her school. My daughter wanted to achieve the high score so that she’d be chosen to represent her school at the Chemistry Olympiad this year. Bill patiently answered all her questions, explained the concepts, gave advice, cheered her on and gave her the confidence she needed to be her best. Needless to say she scored 102% on the test!!! Bill is amazing and a teacher in the true sense of the word.

Excellent tutor, great results!

I was looking for a tutor for my daughter, a sophomore in high school, who needed help in understanding some concepts in science/chemistry and prepare for a test she had the next day. She was very worried she would fail the test. Thankfully Bill responded very quickly and came to our house with only a few hours notice. He was very knowledgeable and patient and my daughter actually enjoyed working with him. And she got an A in her test the next day, which speaks volumes about Bill's ability to teach and help his students understand the material he teaches in only a short period of time, in this case just one hour. We will no doubt ask Bill for help again should the need arise.
