Dr. Matthew Johnson, Neurosurgery

Dr. Andrews Neuro CNOS - ended up with my care because of others who failed to move forward. Dr. Andrews sat down, and we made a plan for future pain care. I truly find him to be very knowledgeable & Honest about his diagnosis. He referred me on to Dr. Matthew Johnson, Neurosurgeon at CNOS, and just made me feel like hope is attainable yet with help of a colleague for Occidental pain. Dr. Johnson and his nursing staff/appointment scheduler where genuinely concerned about me as a person not just 30 min patient. CNOS, I do appreciate your team!

Dr. Daniel Kensinger, Orthopaedic Trauma Care My knee cap was split in two when I hit a cement stair with my knee. I then met Dr. Kensinger and he informed me what to expect after my operation. After surgery, I was treated with the utmost care. Dr. Kensinger informed me of what I needed to do to complete my recovery. His bedside manner was top drawer. He is a doctor that actually listens to his patients and cares about them. I can't say how grateful I am to have had him as a surgeon. Just let me say he is one of the very best all-around in my experience. I am making an amazingly fast recovery due to his advice and direction.

The care and sufficient knowledge of what I needed to have done to get better and get back to a life of health, safety, mental strength, and clarity.

Dr. Phisitkul and his nurse went above and beyond any expectation. Not only did he fix a botched surgery from another doctor, he repaired my foot and created a way for better range of motion for that foot. I cannot express my gratitude enough for what he did for me and my quality of life. He has made it possible for me to work the crazy hours that I love, exercise again, and sleep without waking up with pain. The nursing staff at the Surgery Center are wonderful as well. I will happily refer everyone I know! Thank you so much!
