Dave helps you understand and even enjoy your science or math class!

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 ... [more]


Algebra 1

My tutoring experiences indicate that difficulty with more advanced mathematics or sciences are often caused by weaknesses in pre-calculus math. Please allow me to help you establish a solid foundation for your future through tutoring you in algebra I.


Algebra 2

My tutoring experiences indicate that difficulty with more advanced mathematics or sciences are often caused by weaknesses in pre-calculus math. Please allow me to help you establish a solid foundation for your future through tutoring you in algebra 2.


Biology

As an undergraduate, I earned a minor in Biology; my Ph.D. & years of industrial research experience were in Biochemistry. Whether you are beginning general biology, exploring molecular or cellular biology, studying the biology and genetics of whole organisms, or conducting field studies, I can help you enjoy the journey.


Chemistry

I have a B.S./M.S. in Chemistry and a Ph.D. in Biochemistry. After two decades of industrial research in biochemistry, I taught college level Chemistry for several years. Whether you are encountering difficulty with a beginning chemistry at the high school or university level or a more advanced course, I will try to help you master the concepts and enjoy the course.


Geometry

My tutoring experiences indicate that difficulty with more advanced mathematics or sciences are often caused by weaknesses in pre-calculus math. Please allow me to help you establish a solid foundation for your future through tutoring you in Geometry.


Prealgebra

My tutoring experiences indicate that difficulty with more advanced mathematics or sciences are often caused by weaknesses in pre-calculus math. Please allow me to help you establish a solid foundation for your future through tutoring you in Pre-algebra.


Trigonometry

Many instructors teach trigonometry in a manner that is difficult to understand and apply. I enjoy teaching trigonometry so that it makes sense and you can apply its concepts to real life situations.


Portuguese

I lived in Brazil for five years; fluent in written and conversational Portuguese.


ESL/ESOL

I have lived in Brazil for a total of five years and can both speak and write fluently in Portuguese. As a native American, I can communicate English effectively, both in verbal and written formats. For several years, I have enjoyed teaching Brazilians to speak English and helping native English speakers to converse in Portuguese.


Biochemistry

I have a Ph.D. in biochemistry; 20+ years research and four years university faculty experience. I have a passion for teaching biochemistry because it joins the concepts that I enjoyed most from my undergraduate studies in biology and chemistry.


Physiology

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.


SAT Math

The SAT Math exam demands a comprehensive understanding of multiple concepts of pre-calculus mathematics and will challenge you to apply that understanding to perform practical computations. My formal education in science and mathematics, combined with decades of college level instruction and tutoring and my research laboratory experience, will help you to master and integrate challenging concepts and achieve an understanding that will result in superior test scores and a sound foundation for higher education.


GRE

The GRE exam will not result in superior performance based upon last-minute cramming. I can assist your preparation so that you can relax on exam day and be pleased with the results. I look forward to working with you.


GED

Congratulations on having the courage and the determination to complete your GED! For many students, math is one of the greatest obstacles to completing your goal. I enjoy teaching non-traditional students and can generally help them to move quickly and confidently from theoretical concepts to practical applications.


Physical Science

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.


ASVAB

The ASVAB exam assesses your aptitude for various military and civilian careers and the probability of your enjoying a rewarding career. Although my professional experience is primarily with the math/sciences disciplines that support the Arithmetic Reasoning (AR) and Math Knowledge (MK) of the ASVAB, I also have significant para-professional experience to assist your success with the Verbal Composite sections.


ACT Math

The ACT Math exam requires a blend of understanding basic mathematical concepts and applying that knowledge to practical computations. My formal education in science and mathematics, combined with decades of college level instruction and tutoring and my research laboratory experience, will help you to master and integrate challenging concepts and achieve an understanding that will result in superior test scores and a sound foundation for higher education.


ACT Science

The ACT Science exam requires a unique blend of understanding basic concepts of science and applying that knowledge to data interpretation and reasonable conclusions. My formal education in the sciences, combined with decades of research laboratory experience, can complement your personal knowledge of scientific concepts with application of the scientific method to interpret laboratory results and arrive at a logical and correct course of action.


MCAT

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.
