Dr. David Lincoln

Credentialed expert in Primary Spine Care and Neurology

Dr. Lincoln was raised in Santa Rosa, California, and graduated with honors from Cardinal Newman High School before pursuing a Pre-Med degree at UC Davis. Initially focused on becoming an anesthesiologist, he suffered a back injury that left him in pain and unable to stand straight. Despite trying various treatments, including medications and exercises, he found no relief until he visited a Doctor of Chiropractic who diagnosed him and provided effective treatment. This experience sparked Dr. Lincoln’s interest in chiropractic care, and he went on to earn his Doctor of Chiropractic degree from Life West Chiropractic College in 1999, graduating with Magna Cum Laude honors and an additional certification in treating extremities.

After a year in practice, Dr. Lincoln realized that being a general chiropractor wasn’t enough, and he aspired to become a recognized expert in his field. He pursued the highest levels of education through Board Certifications and Fellowships, completing several programs and earning recognition as a Board Certified Chiropractic Neurologist and Fellow in Functional Neurology. He also completed a 2-year Fellowship in Primary Spine Care and is currently pursuing a 3rd Fellowship in Spinal Biomechanics and Trauma, all recognized by SUNY Buffalo Jacobs School of Medicine and Biomedical Sciences. Additionally, he has earned multiple qualifications through Cleveland University’s ACCGME-recognized coursework, including Hospital-Based Spine Care, Primary Spine Care, Trauma, Evaluation and Management, and MRI Interpretation Review.

When he’s not working in his clinic, Dr. Lincoln enjoys spending time with his wife and three children, playing sports, hiking, kayaking, and golfing. He is dedicated to helping patients achieve optimal health and wellness through personalized chiropractic care and continues to pursue the highest levels of education in his field to stay at the forefront of spine care.
