Query: Brilliant surgeon and author

Dr. Firlik performed neurosurgery on me a year ago, and gave me back my life. She freed me from the debilitating pain that had impaired all aspects of it. I was unaware of this book when I first engaged her to be my surgeon, but was comforted in hindsight that I had made such a wonderful choice of doctors. Her experience and skill brought me to a full recovery. This book both inspires and educates. I hope that you never need Dr. Firlik for yourself or a loved one, but be comforted in knowing that if you do, you couldn't be in better hands.
