Dr. Marc A. Lewandoski

Founder and Chief Medical Officer

Dr. Lewandoski is the founder and Chief Medical Officer at South Shore Medical Care.

Dr. Lewandoski received his Baccalaureate from SUNY Stony Brook, and then attended the New York Institute of Technology College of Osteopathic Medicine (NYITCOM) in Old Westbury, N.Y. for his medical degree. Dr. Lewandoski graduated NYITCOM in Old Westbury, N.Y. in 1997, completed his rotating internship at Good Samaritan Hospital in West Islip in 1998, and his residency in Family Practice at the Good Samaritan Hospital in West Islip in 2000.

He was the first official acceptance to his class, for which he received a scholarship. He graduated in the top 5% of his class.

Dr. Lewandoski was the only student of his graduating class to be awarded the Dr. Shepard Splain Excellence in Surgery Award for top honors in that discipline. He was heavily involved in research with the Department of Biomechanics and was the most published student in his graduating class.

Dr. Lewandoski has 20 years of experience in Primary Care. He is a member of the American Osteopathic Association (AOA), and the American College of Osteopathic Family Physicians (ACOFP). Dr. Lewandoski is also the Medical Director of South Shore Medical Care Physical Therapy, a state of the art 2000 square foot facility located in his medical office building. Dr. Lewandoski also tests and treats patients for allergies in a dedicated facility in the same building.

Dr. Lewandoski had initially considered a career in a Surgical Subspecialty but decided to follow the path of Primary Care. “I felt that the direct contact with my patients suited my personality, and the myriad of disciplines encompassing Primary Care offered me the challenge needed to fulfill my passion for medicine.” Dr. Lewandoski attended a residency program in Family Practice at Good Samaritan Hospital Medical Center. When he is not practicing medicine, Dr. Lewandoski enjoys spending time with his loving wife, Sheila, and the newest addition to the Lewandoski clan, Luca James Lewandoski. He also enjoys working in his garden and restoring antique cars.
