Meet the Doctors

Dr. Gerald Collins, D. C.

I have been in practice since 1986. I pride myself in delivering quality health care specifically designed for your individual case.

I have a vast medical background and started my career as a Hospital Corpsman in the US Navy. While in the Navy, I attended school wherever I was stationed. I attended George Washington University, Florida Southern College, and The University of South Florida prior to my acceptance into Life Chiropractic College where I earned my Doctor of Chiropractic degree.

I am a member of the Jefferson County Chiropractic Society and Alabama State Chiropractic Association. I am the previous president of the Board of Chiropractic Examiners and have been appointed to the Radiation Advisory Board of Health. I am an instructor for the Alabama State Chiropractic Association Board Rules and Regulations.

My post graduate studies include Acupuncture, Accident Reconstruction through Texas A and M, Impairment Rating American Medico/Legal, Acquired Immunodeficiency Virus through Florida Department of Health, and Soft Tissue Injuries.

I will listen to you and what you are describing as your symptoms. I will study your health history along with my examination findings and render my opinion as to your diagnosis, treatment, and outcome.

You can assure that you will receive honest treatment options and the proper referrals to outpatient diagnostic studies and to other medical professionals if needed.
