Jeffrey E. Zuke, M.D., F.A.C.S., – General Surgeon and John D. Hirsch, M.D., F.A.C.S. – General Surgeon founded an independent surgical practice in July 1985 with the intention of providing surgical excellence. They were highly trained, innovative surgeons who were well received by their peers. With the desire for continuous growth in multiple areas, they envisioned adding partners from various surgical specialties over time. In 1990, when Larry Mendelow, M.D., F.A.C.S. (July 1, 1990 – Colon & Rectal Surgeon) joined the group, Suburban Surgical Associates (SSA), Inc. was established in the West County area.
