Kristin Wittmayer, MS, OTR/L

Director of Move U

Connect with Kristin: Kristin.Wittmayer@TheMoveU.com

My name is Kristin, and I am an occupational performance therapist with a lifelong passion for learning. Working with children and others with developmental, coordination, behavioral, and/or learning challenges has always been my passion. That passion has led to multiple specialties and advanced training in which I am the only certified provider in the region.

I began my career within a pediatric hospital setting, gaining inpatient and outpatient experience and working within various multidisciplinary specialty clinics. After 11 years, I transitioned into a private clinical setting where I could more readily provide occupational therapy services in a way that matched my clinical expertise. Nearly 4.5 years later, I am transitioning once again to a partnership where I will be able to utilize my expertise to impact the lives of even more individuals. I practice in an expansive sensory enriched environment, which will undoubtedly be motivating and fun for children, community-based education opportunities, and opportunities to participate in the development of adapted programming.

It truly is my pleasure to get to work with your children and make a positive impact on their lives.

Occupational Therapist

Connect with Kylee: Kylee.Withrow@TheMoveU.com

Welcome to Move U! My name is Kylee and I am from Elk Point, SD, and completed my bachelors degree at South Dakota State University. This past May, I completed my doctorate of occupational therapy with a specialization in pediatrics. During OT school, I completed a number of pediatric-focused trainings, including DIRFloortime and the SD LEND program— which connected me to Move U and created the opportunity for me to be a part of this incredible team!

In my free time, I enjoy being outdoors, running, cheering on the Jackrabbits, spending time family and friends, and going on road trips to the mountains.

I am overwhelmed with gratitude and joy to be part of the Move U team! From my first experiences with Move U as an OT student, I knew this was a really special place. Move U is driven to provide the highest quality care for children and families with effective, client-centered, and fun treatment sessions. It is a privilege to help children become their most confident, joyful selves!

Founder & Visionary
Connect with Nathan: Nathan.LeMaster@TheEmpowerU.com

My name is Nathan LeMaster and I am the founder and visionary for Move U. The genesis of Move U stimmed from the client response of its big sister company, Empower U. Through our time working in cash-based physical therapy, we had noticed that our model was truly client-centered as it created an unmatched relationship with your care provider you cannot find anywhere else. We are proud of the brands we offer as they are family-centered and relationship-driven, with trust and loyalty to our clients built into the center of everything we do. At Move U we strive to promote a fun and progressive atmosphere for all who join us on this journey!
