Dr. David Clark

Dr. David Clark is a Chiropractic Internist [DABCI] and a Naturopath [NMD]. He has been in private practice since 1975.

Dr. Clark is President Emeritus of the Missouri Naturopathic Medical Association, and past Vice- President of the American Board of Chiropractic Internists. He is a Diplomate of the International Board of Diagnosis and Preventive Medicine, and Diplomate of the American Board of Chiropractic Internists. He has served on the faculty of Cleveland Chiropractic College, and John Thomas College of Naturopathic Medicine. He is on the board of Missouri Chiropractic Injectable Nutrition Association. Dr. Clark has taught many post- graduate classes for doctors on laboratory interpretation, physical examination and diagnosis, and alternative treatment methods.

David Clark intended to become a medical doctor and was accepted for advanced placement at both Johns Hopkins and University of Pennsylvania medical schools. When his own health issues could not be helped by traditional medicine and drug therapy, he found incredible help from a doctor practicing alternative medicine. For that reason, he changed direction, and pursued education in natural health care.

More than 45 years ago, people from all over the country began to hear good reports of his success in treating chronic illness with alternative methods and began traveling to his little office in Oak Grove, Missouri. Since 1999, he more than quadrupled the size of his office to accommodate patient volume and make Health Plus Clinic what it is today!

Melissa Abramovitz APRN/FNP-BC

Missy has been a RN for 20 years. She graduated with her Master’s Degree as a Family Nurse Practitioner in November 2019 and passed her board certification exam in March 2020. 16 years of her nursing career she worked in the emergency department, and 10 years ago she was introduced to the concept of functional medicine/integrative/holistic medicine when she attended a seminar called cancer killers.

While studying for her Nurse Practitioners license, she realized she did not want to prescribe pills just to mask symptoms, she wanted to help patients, herself, and her family get well from the inside out. She wanted to get to the root cause of the medical problems and reverse it.

Missy has 9 children, 5 of which she birthed. She lives on a farm with several animals and plans to soon raise her own meat.

“I believe it was fate that led me to the Health Plus Clinic. I had my mind set on helping my patients to not just heal but to thrive, and to live happy- healthy- vibrant lives.”-Missy
