In 1940 Frank Koelzer, a drug salesman from Detroit, moved to Grand Rapids along with his wife Katherine.  In 1945 they bought Treat's Pharmacy and changed the name to Kay Pharmacy.

Jim Koelzer, the son of Frank and Katherine, began at the family business right from the start as a teenager.  After working at the store through high school Jim attended Purdue and served in the Navy.  Jim returned to the store in 1956 and served as President until 1997.

Mike Koelzer (Frank's grandson) began at Kay Pharmacy in 1980 as an eighth grader.  Like his father Jim, Mike attended Purdue where he graduated from Pharmacy school in 1991.  Mike took over as President in 1997.

Kay Pharmacy's continued mission is to improve the quality of life of our customers through pharmacy and home medical equipment.
