Meet Our Team

Jim Zenk – Owner and President

Jim closeup headshot

Jim grew up in a large family in the Twin Cities area and has lived in St. Paul with his wife, Heather, and their two children for twenty years.  Trained as a mechanical engineer, Jim worked for 3M and MTS Systems with extensive experience leading development teams before launching SYNERGY HomeCare in 2009.

“I really feel like I’m in this business because of my mother.  She was diagnosed with Alzheimer’s disease in 2001, and my father, siblings and I cared for her for six years.  She wanted to stay in the home she loved, so we worked to make that happen, but it was a struggle.”

Jim’s memory of this experience is never far from his mind when working to place caregivers with clients. He runs his business with integrity and compassion, and an honest understanding of what it is like to need, or offer, care.

Jim graduated from Iowa State University with a B.S. in Mechanical Engineering, and from the University of Minnesota with a Master’s Degree in Mechanical Engineering.  He enjoys downhill skiing, carpentry, coaching swim team, spending time at the family cabin, and watching Vikings football—even when it hurts.
