Toni Johnson
Patient Educator
My passion for helping others warms my heart and is what keeps a smile on my face. I was born and raised in Las Vegas, Nevada. I left Las Vegas in 2010 after receiving my Bachelors degree in Business Marketing. I also study Thai Yoga Bodywork and love practicing on my friends and family. Moving to Denver was the best thing that ever happened to me. I love the outdoors and being in a city that is so active and health conscious. Being apart of the team at Downtown's Chiropractic Centre is extremely fulfilling and the best part of my career. I get to do what I love while helping the community. Chiropractic has changed my life greatly in so many wonderful ways, and it gives me great pleasure to go out and let people know about all the health benefits.
