I can’t tell you how much I appreciate Dr. Mary Davenport! I truly believe she saved my life. I had pneumonia and it wasn’t treated appropriately by a local doctor. Her protocol worked! I couldn’t breathe deeply right away but I felt like I could breathe easier within 2 days. Amazing! She called and checked on my progress and adjusted medication as needed. Thank you, Dr. Davenport, for your care, concern and wisdom. -Cheryl
