Growing up in Ohio, close to a large greenhouse, Dr. Theisen discovered an interest in Horticulture. In 1995, he earned a degree in Greenhouse management. He then worked full time in big wholesale greenhouses in Ohio, Michigan and Wisconsin. While living in the Green Bay area, he enrolled at UWGB with an interest in a Bachelor Degree in Horticulture. He changed his degree path to Health Sciences with a minor in both Chemistry and Women's Studies. Upon completion of his degree in 2004 from UWGB, he enrolled at Palmer College of Chiropractic where he received his Doctor of Chiropractic degree in 2008.

Theisen Chiropractic first opened in 2009 and had moved several times, before finding it's first full time location with Dr. Theisen keeping regular hours.

While attending Palmer, he met his wife Anita and they were married in 2007. Since then, they have had 4 sons.

Dr. Theisen hasn't given up his passion for Horticulture education - it's now his hobby and he loves to share it with his children. Together they grow an abundance of plants, which are also offered for sale in the office.

Dr. Theisen truly enjoys helping people and will always try to do what he can for others.
