Our Doctors and Practitioners

Dr. Darren Schmidt

Dr. Darren Schmidt, nutrition response testing practitioner, chiropractor

Dr. Darren Schmidt, Nutrition Response Testing Practitioner, Doctor of Chiropractic

Dr. Schmidt wanted to become a doctor so he studied pre-med at Ohio State University. Before applying for medical school, he began to ask questions of medical students and doctors about their profession. Not one of them encouraged him to follow in their footsteps. He decided to investigate other health professions like podiatry, optometry and veterinary and ultimately he decided to attend chiropractic school. He had spent a few hours with a chiropractor in his hometown and liked the natural and wholistic approach. He graduated in the spring of 1997 from the National College of Chiropractic in Chicago. He then opened a practice in Toledo for 3 1/2 years. He moved to Ann Arbor in 2000. Dr. Schmidt is originally from Swanton, Ohio.

Connie Kelly-Saur

Connie Kelly-Saur, Nutrition Response Testing Practitioner, B.S. Medical Science

Connie Kelly-Saur has a B.S in Medical Science, with a background in Biochemistry. She studied pre-med in her undergrad and was on her way to Medical School when her health prevented her from attending. She saw multiple specialists, was now taking a total of ten medications, but they were still unable to figure out what was wrong. Without feeling any improvement, or finding any answers, Connie heard about The Nutritional Healing Center of Ann Arbor, and how real food and nutrition was used to heal the body naturally. She began as a patient of Dr. Schmidt’s in 2009, and with time and commitment to her program, she was able to come off all of her medications. After experiencing firsthand how Nutrition Response Testing helped her feel better naturally, Connie decided to become a Practitioner. Now she helps others improve their health and heal the body with whole food nutrition. Connie sees patients Tuesday through Saturday. My Health Story

Dr. Joel Vickers, Doctor of Chiropractic, Applied Kinesiology

Dr. Joel Vickers earned his Bachelor’s degree in Human Biology and graduated from National College of Chiropractic in 1991. He practiced in Holland, Michigan for twenty-one years. Over time he observed strengths and weaknesses in various techniques and found Nutrition Response Testing. While attending his first Nutrition Response Testing seminar in 2009, which was taught by Dr. Darren Schmidt, Dr. Vickers told Dr. Schmidt about the lack of energy he suffered for a year due to total shoulder replacement surgery. Within three weeks after following Dr. Schmidt’s recommendations, Dr. Vickers had all his energy back. Because of that experience he knew he had found a total system for nutrition testing. He is excited to be working alongside such talented practitioners and is looking forward to helping others regain control of their health. Dr. Vickers is married to the beautiful and talented Donna Vickers and has two daughters and three granddaughters.
