Timothy E. Lindley, M.D. Ph.D.
As a fellowship-trained neurosurgeon, I provide diagnosis and treatment for back, neck, spine, and neurological injuries and conditions. Using my extensive training and experience, I work with my patients to formulate a plan that always focuses on addressing the problem in a way that minimizes risk and maximizes the likelihood of long-term improvement. I find it incredibly rewarding to put my heart and soul into taking care of my patients and later seeing how much that hard work has improved their quality of life.
I grew up in Alexandria, and I now have the opportunity to return to my hometown to provide the best care possible to friends and neighbors. I am excited to know in my heart that people can now get the best care possible right in their own backyard. When I’m not seeing patients, I enjoy spending time with my family as well as hunting, fishing, and boating.
