I started seeing Warren a couple of weeks after I had a double lumbar disc herniation last December. I was suffering excruciating back and leg pain and had lost 90% of my strength and a significant amount of muscle mass in my left leg. My Orthopedic Doctor expected the recovery to take 6 to 9 months with Physical Therapy. Now, less than 3 months later the strength in my leg is probably at 85% and the pain has greatly decreased and is manageable with the targeted exercise program that Warren put together for me. I credit Warren’s knowledge, experience and caring approach combined with a great exercise app for my unexpectedly fast recovery. Thanks Warren!
