Transfection-services.com is the website for Stefanik Research Initiatives, LLC which was founded by me, David Stefanik M.D. I am the sole proprietor. I am a physician who practiced radiation oncology prior to retirement from clinical practice. I was trained in radiation oncology at Georgetown University Hospital in Washington, D.C. While at Georgetown, I was privileged to spend a year in the laboratory of Anatoly Dritschilo M.D. as an American Cancer Society Clinical Fellow. I learned the techniques of cell culture and transfection in a very intellectually stimulating environment. I maintained my skills in the laboratory over the years. I am now “back at the bench” full time where I enjoy feeding, splitting, and most of all, transfecting cells. I am committed to serving your needs without wasting your money. As a member of the American Association for Cancer Research, I value the work of basic scientists. My goal is to facilitate your research.
