I have been a patient of Dr. Kaldis for almost 20 years. He has always provided amazing care and advice, and I can't imagine needing to consult with any other orthopedic specialist. I will always follow his advice.

Dr Kaldis helped my wife over 20 years ago and she has never had an issue since. Obviously I was going to see him after doctors said I needed surgery. Luckily, I did go to him, with his recommendation of physical therapy and no surgery. #0 days later and no back problems. Very honest and straight forward man. Absolutely the best doctor to have in your corner when you need him. Highly recommend you at least get his opinion.

If you want a doctor who takes the time to answer your questions, Dr. Kaldis is not the doctor for you. The doctor barely spent five minutes in the room before rushing out. I was interrupted when I asked questions and no information was given about what to do for my back. The care summary for your visit is emailed with no information on it.

Dr. Kaldis is the best. Dr. Kaldis completed a 2 tier neck fusion on me in 2005 and have had no problems for over 20 years. I did just visit Dr. Kaldis, after 20 years, for another issue in my shoulder which was totally self inflictive. He is great doctor and I will not use anyone else. The staff at Southwest are awesome people. Thank you all for all your assistance.

I have nothing but good things to say about Dr. Kaldis as I have been seeing him for about 20 years. He's the best and ever since I first went to him for a second opinion for my back I have never had a need to seek out another orthopedic specialist. The first Doctor suggested back surgery, but Doctor Kaldis told me I didn't need it. He was right. Thank you, Dr. Kaldis.
