Steven P. Seizer, MD, has been practicing medicine in Santa Monica for over 30 years. His journey into medicine was influenced by his grandfather, who emigrated from Russia when he was 13. He didn’t speak a word of English, but dreamed of becoming a doctor. Medical school was well beyond his budget, but a degree at Columbia University wasn’t, thanks to a scholarship. He became a writer, and ultimately created and produced Marcus Welby, MD, the very popular television show that featured a beloved family physician known for his exceptional bedside manner. Parts of the show were filmed at Saint John’s Health Center, where his grandson, Dr. Seizer, practices today.

Dr. Seizer certainly hopes to have some of the bedside manner of Marcus Welby. He really enjoys practicing medicine, finding the honest interaction between patient and doctor very fulfilling. He keeps up on the newest advances in medicine, to make the most accurate diagnosis and create a personalized treatment plan for each patient. Dr. Seizer has three sons, and it looks like they too may be interested in following the family’s love of medicine.

When not tending to his patients, he enjoys running, both on trails in the local mountains, as well as on the road. He has completed over 15 marathons. He plays in a weekend beach volleyball game, and always eager for more family time, meets his father for a weekly round of golf. He practices what he preaches: exercise, to stay fit and healthy.
