Exceptional Care.
Steadfast Company.
As a full-service anesthesiology practice group, Great Lakes Anesthesiology provides unwavering expertise – both clinically and administratively – to achieve better outcomes, help healthcare organizations run more efficiently, and provide a stellar work environment.

Mission and vision
for the future.
Our mission is to provide the highest quality anesthesia services. We are certified by the American Board of Anesthesiology and have many years of experience in our specialty.
As a rapidly growing anesthesiology management company, Great Lakes aims to partner with healthcare facilities around the country. We’re also teachers of the next generation of providers through our strong network and academic partnerships. Great Lakes, in association with the State University of New York at Buffalo, sponsors a 12-month ACGME-accredited fellowship for anesthesiologists in Pediatric Anesthesia.
Our proud past.
The roots of our practice go back to a pediatric anesthesia group founded in 1998. We’re tremendously proud to have anesthesia fellows from around the globe come to Buffalo, New York, to learn from us and become experts in pediatric anesthesia.
While our initial focus was on the youngest, most fragile patients, we have expanded our expertise to treat patients of all ages and medical conditions. Over the years, Great Lakes has also expanded the areas we serve. Our service area currently spans Western New York and northwest Pennsylvania.
Meet the Team.
Our ever-growing team is comprised of highly accomplished healthcare providers and business professionals..
