Dirk grew up in the garden center business and is the third generation Jonker. He graduated from Michigan State with a degree in horticulture and managed several Garden Centers in Northern and Southern California. In 2011 he returned to Holland to lead Jonker’s Garden into the future.
Jim Jonker started at Jonker’s when he was less than one year old, his father John changing his diapers on the front seat of the truck. The real work began a couple years later as he received the princely sum of 5 cents per hour for pulling weeds, not exactly his favorite job. Jim loves riding his Harley and can often be spotted commuting on his bicycle when the roads are dry and the temperature is above 25. His duties include, but are not limited to: coaching the team, writing the email newsletter, managing the books, fixing stuff, answering plant questions, pulling weeds, and napping.
Zandra, affectionately known as “Z” manages both the nursery and perennial departments at Jonker’s Garden. Each year she decides which of our approximately 1200 varieties will stay and which are retired to make room for the new varieties she finds from over 20 different sources - mostly local Michigan Farms. Zandra is one of our happiest, most knowledgeable and passionate gardeners.
Dena Giller is Jonker’s Garden’s grower. Dena started at Jonker’s in 1983, after co-owning a garden center in Kentucky for 4 years. She is our resident plant-growing expert.

Starting from seeds and cuttings, she takes care of growing our beautiful plants; all you have to do is pick them up and enjoy them!
If you’ve shopped for bedding plants at Jonker’s Garden at any time since 1993, chances are you’ve been helped by a young lady with red hair. That would be Holly. She’s in charge of bedding plants, from ordering and planting seeds, nurturing her “babies” until they are big enough to transplant into flats and pots. Her final job is to make sure they all make it out to the tables where you can pick them up and take them home.
Bev joined our team in May of 2014. She is responsible for ordering hard goods and gifts in our indoor and outdoor garden shop. Next time you come to the garden shop, check out the beautiful displays she’s done and say ‘Hi’ to the newest member of the Jonker’s Family.

Since retiring from teaching music and directing choir at Holland Christian Schools, Bill Bird has been working nearly full-time tending some of the most beautiful gardens in the Holland area, some belonging to others, some belonging to him. Truly his dream retirement. Although Bill doesn’t technically work for Jonker’s, he’s frequently seen here picking up or potting plants. He presents lots of classes, for Jonker’s Garden, Meijer Gardens, and many other organizations in the region. He lives in Holland with his wife Jenine, and they both enjoy tending their beautiful garden.
Joanne started at Jonker’s Garden in 1989 as seasonal, part-time customer service, plant care-taker, plant-stocker, whatever. She works for Holland Schools, MVP Sports Clubs, and other odd and assorted venues where her many talents are appreciated. She and husband Mike tend a large vegetable garden next to their house, and she continues to get her plant fix by helping us out during our busy season.
Mingo was born in Texas in 1972, where her people moved from Mexico in the early 50’s, seeking a better life. Mingo eats Purina Monkey Chow for breakfast, lunch, and dinner. She enjoys monkey treats in moderation, except in the spring and on Saturdays, when she gets so many visitors she over-indulges. Mingo enjoys her retirement here at Jonker’s, eating Monkey Chow, meeting new people, and running in circles. Come visit her!
