"I hope I can be a valuable member because it’s a wonderful organization that I am proud to have in my community.  I love going to the events here and hope to learn valuable “take home” information as well as contributing what I can to the board and the gardens. I love trees, plants, flowers and grasses and to be surrounded by such will be lovely.  I’m trying to do the same at home as well so we’ll see how I can fit two lovely spots into my life."

Iann Veldhuizen

Iann was raised on a farm on E. Orange Road, 3/4 of a mile from the arboretum.  The farm is no longer there, but her interest in gardening, growing and developing things is still there.  When she retired in 2007, from being a floral designer and bookkeeper, she became a Master Gardener and did most of her volunteer hours at the arboretum.  A couple of years later, she and her husband donated the money for the pergola to be built in the Rose Garden in memory of her parents.  Current project is being on the Master Gardner's Orchard Committee, working on the Orchard at the Arboretum.

Dick was very interested in farming during college, but decided to become a financial advisor in 1988. He began his work at IDS and then moved to Brecek and Young. As years passed, Dick's desire to maintain relationships became stronger, therefore an idea to become an Independent Financial Advisor took hold. Dick is married to Mary and they have two grown daughters, Emily and Alicia. He and his wife love to travel, Ireland being their favorite place to go. Dick is an avid reader, from fiction to non-fiction, adventure to historical, and he's a train enthusiast. He first became involved with the Arboretum on the finance committee and as they say-the rest is history.
