Dr. Grunspan is a full time practicing physician since 1983. What sets him apart from others is the amount of time he spends with his patients. This allows time necessary for information gathering and affords the opportunity to understand each individual’s issues and concerns. In addition, he spends ample time educating his patients about their condition and arriving at treatment goals which are mutually set.
Dr. Grunspan is originally from Cleveland, Ohio. He pursued his interest in biology and chemistry at Case Western Reserve University and the University of Cincinnati where he consistently made Dean’s List and obtained his Bachelor’s Degree in Biology. In 1977, he studied Spanish and immersed himself in Mexican culture spending the next 4 years in Guadalajara, Mexico, where he met his wife who just happened to work for the University. There he obtained his MD degree in 1981.
After medical school graduation, he and his wife moved to New York City where he spent a year at the Albert Einstein School of Medicine, followed by 3 years training at the Mount Sinai program in Internal Medicine. After completing that program, he practiced internal medicine for 17 years in Rochester, New York. He was clinical professor for the University of Rochester School of Medicine and Dentistry, teaching doctors in training, medical students, physician assistants, and nurse practitioners.
Shunning the cold and snow, the family decided to move to warmer climes in 2003 and found themselves in San Antonio. Initially, Dr. Grunspan practiced internal medicine, but also pursued his interest in sleep medicine with a sleep physician in his group. He eventually gained proficiency in the field and became board certified in 2007.
Currently, Dr. Grunspan practices adult sleep medicine and lectures extensively about sleep to local and national medical organizations. He speaks to local community groups and industry about the importance of sleep for their health and productivity. He also has several podcasts on local radio shows on various sleep subjects. He is clinical assistant professor with the University of Incarnate Word School of Medicine and Osteopathy in the field of sleep medicine.
Dr. Grunspan and his wife of 37 years have 2 amazing adult children and love to travel, enjoy nature (especially birdwatching), music of all types, and biking. They rarely travel north anymore unless the snow has melted.
