    Dr. Theo Davidson was born and raised in Hartford, SD. He graduated from Augustana College in Sioux Falls with a B.S. in Athletic Training. From there, Dr. Davidson attended Northwestern Health Sciences University in Bloomington, MN where he graduated with honors while earning his Doctorate of Chiropractic in 2011.

    Dr. Davidson immediately moved back to Sioux Falls where he successfully started and grew Bridges Chiropractic until he left the practice to partner with Dr. Allen Unruh in August of 2018. During those six and a half years, he used his extensive knowledge and training to help people of all ages and walks of life get back to doing the things they love.

    Throughout his career, he has learned how to utilize a variety of chiropractic techniques to help people get well and he continues to learn even more under the guidance of Dr. Unruh. He utilizes primarily two techniques: Cox Technic and Diversified technique. Cox Technic is a gentle, effective form of adjusting that utilizes traction and stretching. Diversified technique is the traditional pushing and popping that many people think of when they think of chiropractic. Dr. Davidson's main goal is making people healthy so they can get back to the things that they most enjoy.
