Dr. Chelsea Vallario is the head Chiropractic Physician and owner of Athlete Recovery & Chiropractic Health. She started this clinic shortly after moving to York County, SC in 2017. She strives to provide movement-based medicine to Rock Hill and her surrounding community.

She has traveled the country to achieve her education and career goals. She was born and raised in the heart of the Rocky Mountains in Glenwood Springs, Colorado. Being a multisport athlete her entire life, she naturally pursued a health- and sports-based education. With her love for sports and activity of all kinds, she was drawn to North Carolina in order to complete her Undergraduate degree. Dr. Vallario studied Kinesiology and Human Physiology at the University of North Carolina – Charlotte. She completed her undergraduate degree in three years allowing her to immediately begin her Doctorate program in St. Louis, MO. She has earned both a Bachelor of Science degree in Human Life Science, and a Doctorate degree in Chiropractic from Logan University (St. Louis, MO).

Dr. Vallario’s love for chiropractic began at age 16 after suffering from severe shin splints and debilitating knee pain to the extent of nearly ending her young athletic career. After a number of physicians were unable to explain or treat the pain, she was referred to a local chiropractor. Finally, someone was able to explain the source of her pain and mechanical dysfunctions causing it. She was treated accordingly and taught exercises to prevent it in the future. Within two weeks she was back on the field pain free for the first time in years.

Building on her positive personal experience, becoming a Doctor of Chiropractic aligned perfectly with her passion for helping others in both health and performance. Dr. Vallario is eager to provide the highest quality, proactive healthcare to her community of Rock Hill, SC.
