Meet Dr. Constantine A. Kotsanis

In his quest for answers, Dr. Kotsanis came across people in other disciplines — such as homeopathy, nutrition, acupuncture, and structural medicine — who opened his eyes to a new world of information and answers. He trained in these other disciplines, and as time went on, he incorporated this new information into treatments for his patients. The best way to describe what we do at Kotsanis Institute is that we blend the relatively new findings of modern conventional medicine with the age-old, time-tested wisdom of older disciplines to craft unique treatments for each person.

"Wonderful experience always. Thank you dr K for taking care of me on Your day off Saturday. Yasmine"



"I noticed the person put in a one star a few years ago. We'll not certain where that came from because Dr Konaisas offers some really top notch care. I have been sick since June 2014 and had seen several doctor's just now starting to see some benefits. Alot a good doctor's out there but no one that will do a complete work up like Dr Konaisas. Very good at understanding the root cause and provides you results. I would highly recommend him to anyone. His staff is professional and friendly. I'm here a few days a week I drive 45 mins from Allen Texas. Honestly I probably drive further for this type of treatment. Alot if options here and you will be amazed. Call them for any of your health issues. Take care."



"Dr Kotsanis, or as many call him, Dr K, is the BEST! He isn't your average doctor. He understands health at its very core. He doesn't treat patients like a number. Each patient is treated as they should be, uniquely, because let's face it, we are all very different, and what might work for one patient might not work for the next. When it comes to health and wellness, Dr K is the BEST! I also have many friends who are patients of his, and all of them have nothing but good things to say as well!"



"My brother, who is a Stage 4 cancer patient, and I visited the Kotsanis Institute to receive a cutting edge treatment. Dr. Kotsanis and his staff are not only friendly, but kind and accommodating. The rooms are especially comfortable with large recliners ( more than one) in the rooms. They offer you water, various teas and even a snack if you want one. It has a family feeling atmosphere, in fact, most everyone who works there has been there a long time. Such a great place, and they offer so many amazing treatments depending on your need. Would most definitely recommend them. Can't find a nicer group of people."



"Tremendously grateful for what this practice has done for me personally as well as my family and friends. I also love knowing that they are helping patients across the country as I've met numerous patients in the waiting room who fly in for treatment from across the U.S. You will not find another facility this proactive or scientifically advanced anywhere in the U.S. Dr. Kotsanis is known around the world by other practitioners and I am grateful that he is in Texas!"
