Karissa Markham

​Karissa spent 10 years as an elementary school teacher before taking a risk and making a commitment to fitness full time.  For her, the love of running came first. Over the past ten years, she has trained and competed in several half marathons, marathons and in 2019, an Ironman. In between all the running, she also became a bodybuilder and CrossFit competitor.  Wanting to share her passion of fitness with others she became certified as a personal trainer, a group instructor, CrossFit Level 1 coach as well as earned a master’s degree in Exercise Science from Oakland University. All of these accomplishments could not have been done without the help and guidance of many coaches.  These coaches paved the way and inspired her and now she wants to give to others what they gave to her…a sense of confidence, empowerment, and success.

Currently she owns and operates MarDock CrossFit with her coach as well as business partner James Dockeray.  Karissa is of the opinion that nutrition plays a large role in not only our physical but also mental well-being.  She is committed to guiding others in their wellness journey and helping them recognize their full potential.
