President Elect:  Jim Rock

I grew up in Des Moines Iowa. I started working for a large tree service there in 1975. My qualifications were that I had a strong back and a chauffeurs license. I loved the work immediately! I worked for another tree service up here in Ames for a couple of years and then started doing tree care on my own starting Ames Story Tree Service in 1981. I started getting the NAA magazine shortly after that and started learning about tree health. 

I received my arborist certification several years ago. I have been to the Shade Tree Short course for many years along with other continuing educational opportunities such as Rochester Arborist Association, Minnesota Arborist Association, IAA, Midwest Arborist Association in various cities. Even though I don't do much production anymore, I still love doing tree care with all its challenges. Jim is also a BCMA.
