Tammy Doan began her HorsePower journey as a volunteer in January of 2015 and found herself filling a very valuable role--Occupational Therapist for the Hippotherapy Program--by May 2015.  Tammy was born and raised in North Dakota and received her Occupational Therapy degree from the University of Minnesota.  She has lived in South Dakota since 1998.  Through her OT career, Tammy has provided her services in a variety of settings including the school system, residential care centers, long term care facilities, community outpatient, and home health.  Along with her desire to help others reach their full potential, Tammy has a love for horses. "I believe the power of a horse to help facilitate therapy goals is a truly amazing and unique experience. I am very excited to be a part of HorsePower’s mission!" 

When Tammy is not at the barn, she can be found cruising the back country roads on her motorcycle, spending time with her family, attending hard-rock concerts with her daughter, or snuggled up to a good Halmark show.  We are so thrilled to have Tammy as a part of our team!

I'm an animal lover, so I was blessed to grow up on a farm where I could be around animals, particularly horses.  At the age of 16, I bought my first horse, Shiraz.  I have added three horses to my herd since then.  My passion for horses and helping others brought me to HorsePower as a volunteer in 2010.  I continue to volunteer at HorsePower when able.

In May of 2020 I earned my Bachelors of Arts in Interdisciplinary Studies, with emphasis in Special Education and American Sign Language from Augustana University.  I work in the Harrisburg School District as an elementary special education aide.

In my free time, I enjoy being with family and friends, spending time with and riding my horses, playing cards, and kayaking.

 Samantha Erickson, Independent Riding Instructor

Hello! My name is Samantha, but most people call me Sam. I’m currently going to school here in Sioux Falls at Augustana and am looking forward to applying to medical school after graduation. Horses have been a big part of my life for as long as I can remember. I’ve ridden for a number of years in both disciplines, though it’s been a while since I’ve worked in an English saddle. When I’m not around the barn I’m usually in class, in the kitchen, or getting outside. I enjoy exploring the many parks here, baking, and going to the farmer’s market in the summer!
