Upon completing my Doctorate in Nuclear Physics I took a NIH fellowship in Medical Physics. After completing the post doc. I became the Medical Physicist for a large New England Hospital. Although my main focus was radiation therapy and radiation safety I devoted significant time to Diagnostic Radiology, Nuclear Medicine and teaching Radiological Technologists. After helping build the radiation therapy program including the design and oversight of a new therapy center expanding the physics staff to three FTE, physicists, two radiation safety techs, and two dosimetrists I moved to Easton MD to start a new career as a single medical physicist with the same responsibilities as before. Again helping to expand department and contributing to the design and installation of two linacs with state of the art capabilities including stereotactic radiotherapy,and IMRT, also helped implement conventional brachytherapy and High Dose Rate Brachytherapy. I retired in 2007 after 31 years as a Medical Physicist. From 2007 to 2014 I cruised with my wife on our 40' sailboat up and down the US east coast and Caribbean. I am now interested in helping math and physics students especially beginners. I have discovered how much I have forgotten I am surprised at what I had known and probably will never know again. But on the other hand I still know or can quickly recall quite a bit of Physics and Math.
