Dr K is my friends dad. I recently was traveling and had an eye problem. I couldn't reach my doctor so I called Dr K whom I had met this past summer. I took a picture of my eye and sent it to him. He diagnosed the problem immediately, called in medicine for me and even checked up on me when I got home. I had an office visit with him a few days later. I've never had a doctor call me at home to see how I was doing. I'm so grateful for him and will make him my doctor as well.

I have found that Dr. Katsigiannis (K) is the most caring, concerned and professional doctor I have ever gone to. When I come in distressed he takes what I share seriously and follows up with me to assure what he has prescribed is working and if not he does not hesitate to make changes where needed. His ability to work with my team of doctors is nothing less than professional! I know I am safe with him as my primary doctor. I not only trust him but I trust my families' health care to him.
