I've had an interesting and fulfilling life that's included having a wonderful family and friends, working in the fields of medicine, engineering, and entrepreneurship, being an inventor where I've obtained patents on medical devices and sporting goods, medical device commercialization consulting, business mentoring, being an educator, and having fun hobbies that include sailing, playing the guitar, scuba diving, and doing underwater and terrestrial photography,

My wife, Janice and I recently moved to Tampa to be near my younger son and grandchildren and, to my pleasant surprise, I've discovered that Tampa is becoming a hotbed of medical technology entrepreneurship. I've become an  Entrepreneur in Residence at the Lowth Entrepreneurship Center at the University of Tampa where I am also developing an intellectual property course for their students, a medical advisor to a startup company, NeuroEM,  that is developing an interesting device that may provide for the non-invasive treatment of Alzheimer's disease, a mentor at the Nault Center for Entrepreneurship at the University of South Florida, where I'm also on a committee that is helping their technology transfer office license their rather substantial patent portfolio, and a member of Tampa Bay Wave which is an accelerator that is currently developing a Med-Tech cohort.


I have a degree in electrical engineering from M.I.T. I went to medical school at the University of Michigan. After internship at  UC San Diego and residency at Children's Hospital National Medical Center, I trained as a pediatric cardiologist at Johns Hopkins. I was in academic medicine for 15 years first as as a pediatric cardiologist at the State University of New York at Stony Brook,  the director of the Catheterization Laboratory director at St. Christopher's Hospital for Children and Chief of the Division of Pediatric Cardiology at the Children's Hospital of NJ. I then went into private practice which I maintained for18 years.

Throughout my career I have always been active in both medicine and engineering. I have 20 medical device patents and a startup, MGI Medical, LLC, which is commercializing one of my patented inventions, the "Pulse Flowmeter'" which can detect hidden blood loss in patient with post-operative blood loss or GI bleeding well before their blood pressure drops. I also have patents on sporting goods for camping, skiing, hockey, and scuba diving. After closing my clinical practice in 2015,  I  received an MBA from the Haslam School of Business, University of Tennessee.

My education, training and certification are on this website. However, my complete and updated profile is maintained on LinkedIn.


My wife, Janice Siegel, and I have been together for more than 50 years. Janice has had a a stellar career as a litigator for the EEOC, the Division of Land and Natural Resources at the Justice Department, an Assistant US Attorney for the Eastern District and New York, and a specialist in environmental class action litigation in private practice. Among her proudest achievements is playing an important role in having 5 pristine rivers in Northern California declared "Wild and Scenic," thereby preventing commercial development; they remained so designated to this day and the rivers are truly spectacular. I call them the "STEAK Rivers" - the Smith, the Trinity, the Eel, the American and the Klamath. She is also a political junkie and community activist. She is on the board and a legal advisor to "The Friends of Brightwood Park" which is devoted to keeping a local nature sanctuary in good condition and preventing it from being used for inappropriate activities.

My older son, Matthew, is a barber and an advanced ski instructor at Stowe. Matthew is an expert at telemark skiing which he has taken to a new level by creating what can only be called "ski dancing." Have a look at his Instagram channel where he has over 18,000 followers. Matt and I recently invented and patented a new skier safely and convenience device that we call "Monkey Straps" and we've started a company to try and commercialize it.

I have a number of fun hobbies including scuba diving, guitar playing, sailing and both terrestrial and underwater photography.
