“I felt awful, overwhelmed, and stressed out about my condition. My family was suffering too. All the other doctors told me I would need to take medications and I really didn’t want to. I never thought I could get myself back on track. Now I am free of the struggles I have dealt with for so long WITHOUT MEDICATIONS. My family and I are so much happier now. I never would have been able to do it if I hadn’t gone to see Dr. Leigh. I consider Leigh Brain & Spine a haven for health.

I am a life-long athlete and ended up with some cumulative lumbar damage that really affected my quality of life after a while. When I first saw Dr. Cosmas Leigh, I had a significant degree of spinal compression at L4/L5 and L5/S1, and I was experiencing sciatica and numbness in my feet when I ran or played soccer. I had previously benefited from manual decompression about 3 years prior to this, but I failed to maintain my wellness, so I was back to square 1. Dr. Leigh worked with me to modify my activity and sporting, learn how to take care of myself, and settle on a good maintenance plan for after my year-long decompression/chiropractic treatment was complete. I now enjoy a great quality of life, and am almost always pain free these days! I’m so grateful and remain totally committed to maintaining my wellness by seeing him regularly for spinal decompression, therapy, and chiropractic adjustment!.
