Ronald F. Zimmerman

Ronald F. Zimmerman, 68, of Baltimore, passed away peacefully at his home on July 31, 2026, surrounded by the love of his family.

Born in Baltimore, Ron was the beloved son of the late Ronald J. Zimmerman and Alice C. Zimmerman.

Ron dedicated more than 40 years to the real estate industry, where he built a respected career as a real estate broker. In addition to his work in real estate, he and his spouse, Steve, fulfilled a lifelong dream by opening The Rowan Tree in Baltimore. It has been a cherished part of the community for the past 23 years, welcoming customers with warmth and friendship.

Deeply committed to serving others, Ron was actively involved in his community and proudly served as the former president of the Allen Center for Seniors in Baltimore. He found great joy in giving back and helping enrich the lives of those around him.

Above all, Ron treasured his family, friends, and the many relationships he built throughout his life.

Ron is survived by his devoted spouse, Steven A. Jackson; loving sisters, Mary T. Zimmerman and Maria C. Kalman (husband, Craig Kalman Jr.); and his adored niece and nephews, Rowan E. Schmincke, Nolan R. Schmincke, Brian Kalman (wife, Melissa Kalman-Cruz) and Matthew B. Kalman. He will also be missed by his great-nephew and niece, Daniel C. and Abigail G. Kalman; mother-in-law, Wanda Jackson; and his brother-in-law, Mel Jackson.
