Dr. Tuder is one of the best doctors I have ever had. He is caring, compassionate, and communicates with his patients as well as his patients’ families, and his staff members are pleasant and efficient. I feel blessed to have had him recommended to me after breaking and dislocating my wrist. If I ever have another injury, I would return to Dr. Tuder.

I was referred to Dr. Hooker by my primary care doctor. Dr. Hooker’s staff was courteous, professional, and caring. I only had a ten minute wait! Dr. Hooker carefully performed an EMG test on me, explaining every step along the way. I’ve had other pain specialist over the years. He is by far the best. I don’t usually write reviews, but for someone like Dr. Hooker who takes their time with you, is professional, and truly knowledgeable, I had to get the word out. I will be going to him from now on.

Dr. Whitney performed my knee replacement, and I could not have asked for a better physician. On my first visit, he answered all of my questions before I even asked them, helping me deal with the anxiety of having surgery. The day of surgery, he came to speak to me and my family and answered even more questions. Then, he prayed with us. Yes, a busy physician took time out of his preparation to pray with his patient and her family. To have such a humble and caring doctor was truly a blessing.

Dr. Charlton saved my husband’s life!

Dr. Whitney replaced my left hip joint. I stayed overnight in the hospital and went home the very next day. I started on a walker that day. After two months, I have to say, the experience has been wonderful. Dr. Whitney is skilled, professional, and compassionate. I never imagined I would have recovered this quickly.

I highly recommend Dr. Tuder. He is a very compassionate and highly intelligent physician who spent time answering all of my questions. I did not feel rushed and felt that Dr. Tuder genuinely cared about my problem. I will definitely see him again if I have any orthopaedic problem.
Dr. Charlton is compassionate, competent, and treated me like I was family.

Dr. Tuder fixed my broken wrist two months ago. Last week, I was able to play at my piano recital. Thank you, Dr. Tuder, for giving me my hand back.

Dr. Whitney is probably one of the most caring, engaged doctors I have ever met. He replaced a knee and repaired a broken femur for my mother in law. Seven weeks later, she was up, walking, and pain free. Oh, yeah, and she’s 81 years old. A truly remarkable physician.

A few years ago, my aunt was in a car accident that shattered both of her legs. Dr. Barber performed multiple complex surgeries to help heal her traumatic injuries. He did an awesome job. He made sure the family was always in the loop. He would send nurses to give constant updates while he was performing the surgeries. Many of these procedures were five to eight hours long. Even after that grueling process, Dr. Barber came out with a smile on his face to let us know how well the procedures went. My aunt is now walking in therapy without assistance. Thank you Dr. Barber for your incredible work.

Dr. Charlton was very confident and professional, and is staff is very courteous. He did an excellent job restoring my broken collar bone. I would definitely use him again.

Before I saw Dr. Tuder, I had visited two other hand surgeons who were unable to diagnose my problem. Dr. Tuder, on the other hand, was confident, conservative, and he fixed my hand and wrist issue without difficulty. I highly recommend him.

Dr. Charlton and his staff are experienced, professional and knowledgeable. They put my foot back together after a traumatic injury.

I am not usually one to write a physician review, but Dr. Whitney had a profound impact on me in a way I can’t deny. He didn’t just do an outstanding job on my surgery. He prayed with me. He sat there and prayed with me! It took my breath away. What surgeon has time for that, or even cares enough to think of it? I was so impressed, and am doing so well post-surgery, that I had to share what a remarkable man and physician he is. Thank you Dr. W!
