Cleo Schroeder

Supervisor / Coach

Cleo is an Arkansas native and relocated to the big city of Milwaukee in September of 2021. She specializes in getting pets and boops from her clients and making sure those rest periods are long enough to do so. You’ll also be required to help her get treats out of her pineapple toy when it’s just too hard - she’ll show you, don’t worry. Cleo has a PhD in Wiggles and the Art of Looking Into Your Soul. She's very diligent about practicing her skills and keeping current with the newest methods. She looks forward to sharing these skills with you in your next training session!

We Value the power of connection, community and continuing education.

  • CONNECTION

    We first learn who our clients are, what they value, and what their underlying motivation is before finalizing goals and determining which of our services will best help achieve them. We meet our clients where they’re at. We recognize that major life changes like illness, grief and loss, career changes, and much more affect the physical and mental wellbeing of our clients, and we support them by modifying expectations to make space for these events. We have our clients' backs during their greatest victories and most difficult struggles.

  • COMMUNITY

    We recognize our strengths and our limitations. RunFit’s Team values establishing close professional relationships with medical experts and other wellness practitioners that round out the coaching and training we offer.

  • CONTINUING EDUCATION

    Our clients rely on our certified professionals with education and expertise in personal training, nutrition coaching, running coaching and menopause coaching. Our team relies on scientific data, proven research, and ongoing education to guide our recommendations. 

Strength comes from within. We’ll help you discover it.
