BOARD OF DIRECTORS

JEFF MOZENA | Chair

Jeff Mozena is retired President/CEO, and current Chairman of the Board of Premier Bank, Dubuque, Iowa.

From my early days picking black raspberries on the Marshall farm and meeting Mac Marshall on his porch for a drink of well water, I knew his farm was unique ... filled with trees and vegetation. I’m certain he would be pleased to see the beauty created in his memory. My uncle, Mel Gottschalk, assisted with the development of the Rose Garden and was active with the beginning of the gardens. Today we add to his legacy with the recent addition of the Edna Mozena Conifer Garden. The gardens provide a place of beauty to relax and enjoy nature. We welcome all to enjoy the work of the Dubuque Garden community.”

MERLIN GREEN | Board Member

Merlin Green grew up on a farm in southwest Minnesota, learning to drive a tractor at the age of 5!

After completing a degree in Agricultural Engineering at the University of Minnesota, he and his wife Jo moved to Dubuque where Merlin began his employment at the John Deere Dubuque Works in the product engineering department. Most of his career involved developing software for the rapid analysis of field test data.

My volunteering at the DABG started with taking over the project of mapping and inventorying our trees and plants in the gardens. That work continues, but the computer background has evolved into the support and development of much of the office and gift shop software and processes.

For me, the Dubuque Arboretum has become a 'haven' where the beauty and peacefulness fulfill many personal needs."

Growing up in Dubuque, going for a peaceful stroll in the gardens was a memorable part of my childhood. My favorite garden has always been the one I called the 'Bunny Garden' and, to this day, I always have to check on my grandpa's oak tree, growing tall atop the hill overlooking the pond. During summer months, you may spot me in the Arboretum plein-air painting from time to time. The Arboretum is the perfect place to find inspiration, cheerful color, and peace! I have always loved the Arboretum, so I couldn't be more thrilled to be a part of the board! I look forward to this wonderful opportunity to give back to our community, and apply my creative mind to something already so beautiful!”
