The staff here is always friendly and welcoming. I saw Dr Holt and I could not be happier with the result. KOC has been extremely helpful and professional.

Report
Where to begin; very cattle like feel to the whole experience. similar to Aspen Dental, Value Vision, and other companies that try to funnel people through a system to get as many people through the gates as possible; little to thoughtfulness or respect for the patients' time of concerns even when problems still persist. -Every problem with KOC is resolved with surgery. -Every appointment is a minimum 1.5 hr wait to see someone who is more interested in getting out of the room and saying that it requires surgery. -Then they want as many return trips as they can squeeze out of the patients. -The scheduling doesn't know which location they are scheduling so every appointment is a 50\50 opportunity that the scheduling is right on their end even though their automated system tells you a certain location. I tend to believe that all this is to allow them to double book appointments and to bump people when more "important" customers need a to seen.

I just want to say how much I enjoyed working with Dante and Brent. They were so professional and friendly. I had to take my 21 month old daughter to a walk-in appointment because her foot was injured. Coming to a large clinic like KOC, I thought we would be ushered in and out like cattle. This was not the case. Dante and Brent treated us like we were real people. They took the time to sit with my daughter and me. You have two very special people on your staff! Thanks for the great treatment.

The staff and physicians are extremely professional and polite. Dr. Calhoun and Dr. Crawford are my two favorite doctors at KOC! Dr. Calhoun has done both my hand surgeries for worker's compensation and I trust him completely. I first met Dr. Calhoun when he repaired my son's shattered finger from a high school football game. Dr. Crawford has been treating my granddaughter's foot since birth and has been taking a conservative approach to her treatment rather than just jumping into surgery.

Dr. Mathien has repaired both my knees. I like how he takes time to answer all my questions & concerns. His bedside manner is great! He tells it like it is so you know what is going on to help his patients make well informed decisions on their medical treatments. I dread my knee replacement, but I know when it happens, I'm in good hands with Dr. Mathien as my surgeon.

I had a scaphoid fusion. I would recommend Dr. Ivy to anyone that has wrist or any other joint pain. He is excellent. I had been dealing with pain and numbness from my wrist for a couple of years and now it's almost completely gone. I still have good movement of my hand and wrist. Scarring is minimal. Thank you so much for helping me get my life back Dr. Ivy!
