Dr D

Elizabeth Casos Draney, D.C. - Owner, CEO, Chiropractic Physician

Dr. Draney knew from the time she was a teenager, working in a chiropractic clinic, that she wanted to be a chiropractor. She completed her undergraduate work at BYU and then left the chilly weather to attend Los Angeles College of Chiropractic in southern California. She graduated as Salutatorian of her class in 2000 and returned to Utah where her family had migrated. While in school she obtained a fellowship in pediatrics and pregnancy from the International Chiropractic Pediatrics Association and Webster's Technique certification. She serves as a board member on the Utah Chiropractic Physician's Association and the non-profit ChiroHeroes organization.

In 2020, Dr. Draney added board games to the waiting room to provide opportunities for social interaction, brain stimulation, and laughter. Playing board games with her children, family, and friends is at the top of her all-time favorite activities. She is an escape room expert "wanna be", burrito lover, occasional golfer and scuba diver, and loud fan at the Broncos games. As of August 2022, all four of her children are in college and her fingers are crossed that her boys will stop playing video games all the time and her girls will get along as roommates.

Dr. Draney expanded her chiropractic clinic in 2020, and started R Haus Spa, a sister company to USAC. She wanted to provide esthetic services so clients can feel as good on the outside as as the do on the inside. She has an unquenched thirst for acquiring knowledge in all thing's chiropractic, Whole Food Plant Based nutrition, functional movement, essential oils, and evidence based medical decisions. Patients have been turning to Dr. Draney for over two decades in search of conservative alternatives to medications and invasive procedures.
