RHIANNA HANSON, PT, DPT

Physical Therapist

I am excited to be part of the OSPT team! I graduated with my clinical doctorate in physical therapy in 2016 from the University of Wisconsin - La Crosse.  I have experience in outpatient orthopedics and older adult inpatient settings. I particularly enjoy treating chronic pain, reducing falls risks and improving overall function in older adults, and managing pain and fitness in pregnancy/postpartum. I am excited to continue to expand my skillset here at OSPT and look forward to working with you.


Outside of work, I enjoy staying active just as I recommend for my clients. I love hiking, road biking, golf, yoga, basic weight lifting, gardening, tending my houseplants, singing, crafting, and taking stroller walks with my little girl.  I live in Kasson with my pastor husband and our beautiful little daughter.  One last thing to know, I am from Wisconsin and proud of it!

SCOTT NELSON, PT CERT DN. TPI CERT

Physical Therapist, Owner

I grew up in Northern Minnesota and graduated from The College of St. Scholastica with a BA in Biology and received my Master’s Degree in Physical Therapy from the University of Minnesota in 2001. I have a Certification in Functional Dry Needling from Evidence in Motion and I am Certified by the Titleist Performance Institute to perform joint flexibility and stability assessments as they pertain to the golf swing. 

I have spent most of my career working in outpatient orthopedic clinics but have experience in acute care.

My wife Brenda and I moved to Faribault in 2005 and to Owatonna in 2012. During my time in Faribault, I worked in a similar setting providing physical therapy to patients with musculoskeletal pain and I was also fortunate to work with collegiate and professional athletes.  We have owned OSPT since 2018.  We have 6 children and enjoy camping, playing sports and the outdoors. I also coach hockey for the Owatonna Youth Hockey Association.
