"David W, M.D. is a physician, astrobiologist, space medicine researcher, science communicator, and author, whose public appearances explaining science have included Oregon Public Broadcasting TV and numerous panels and interviews on various podcasts and radio shows. David is director of medical research for a startup science technology company and authors continuing medical education materials (CME) for physicians and is a contributor to Medscape and to various magazines and other media outlets,. He also authors practice questions and answer explanations for the United States Medical Licensing Exam (USMLE), the Medical College Admissions Test (MCAT), and other such exams. Not only has he written practice test questions for these and other exams and for related science topics, but he has experience tutoring students of a range of levels, from college through medical students, nursing students, and other health science learners.

David loves explaining many of the very subjects that often scare students in medical school, premedical students, and those studying, or preparing to study, in the health sciences. Rather than teaching you mnemonics and helping you to memorize without understanding, as is common in the health sciences, David will help you to understand the material, so that you don't need to memorize, except when absolutely necessary. As an example, if you to learn which ECG leads show pathology in which parts of the heart, you can do this by learning the electrophysiology and deriving what shows what based on the locations and polarities of each electrode. If you expect to memorize everything without conceptualizing, do not seek David as a tutor. But if you want to be one of the students who knows --and enjoys-- the material, because it makes sense, contact David and he will guide you through the beautiful mechanisms that manifest from the molecular to the gross level in physiology, biochemistry, and all of the areas that may be giving you trouble. He can tutor you in English, or in Spanish." less...
