Constantine A. Kotsanis, MD, Medical Director

Board Certified Otolaryngologist, Certified in Clinical Nutrition

Dr Kotsanis

I was born in Greece and came to the states as a teenager. My family settled in Chicago, where I attended Austin High School and went to Northern Illinois University (go Huskies!). I then returned to Greece for medical school at the University of Athens. I did my specialty training in otolaryngology, head and neck surgery at Loyola University of Chicago which is when I met and married my wife Beverly.

Life has always been an adventure. Bev and I have two wonderful children, Andrew and Katerina who add spice to an already busy schedule. Both of the kids have participated in the practice over the years, and someday I hope one or both of them can take it over.

Although I began my medical career quite conventionally, at one point some years after beginning medical practice I began to experience health problems. After extensive testing I was told nothing was wrong with me. All I knew was that I was in pain, fatigued and experiencing severe gastrointestinal issues. This experience taught me that sometimes you have to look for answers in less conventional places. This was before Google existed and before the Internet was readily available to most people. I had to find my answers the old fashioned way – books, journal articles and other sick people.

I come from a large family. My father was the eldest of 18 siblings and I am the youngest of seven, three brothers and four sisters. As you can imagine, with a family that large, and with people as mobile as they are these days, we now have family all over the world. So we travel often to visit the many friends and family we have amassed over the years. While traveling we always connect with local medical people and learn what they are doing. We love exchanging ideas. Bev and I are also conference junkies. Being up on trends and new research findings is important, so our travels help us learn while we catch up with people. Additionally, because my patients know that we are open-minded and interested in new technologies, they are constantly bringing us new information.

Although we keep an open mind, a certain degree of skepticism should always exist to balance the enthusiasm that may come with an idea that sounds too good to be true. Because we still ask a lot of questions, we do some original research in house to test and research new ideas before offering these to patients. We have done, and continue to do clinical trials in house under Investigational Review Board (IRB) guidelines. These studies have brought important findings that are then shared with other health professionals. In addition, our contribution to our local community includes various types of interns who spend time learning and doing projects in our Institute. These range from short high school projects to lengthy one-year studies at the post-graduate level.

We always look forward to the next challenge and hope you will decide to become a part of the family of patients and professionals who will help lead us into a healthier and brighter future.

Beverly Kotsanis

Chief Executive Officer

I’m Beverly Kotsanis and I have been Operations Manager since we opened our doors in Texas in 1983. I have a Bachelor of Science degree in psychology from Loyola University of Chicago and have attended postgraduate studies in business at Rosary College, River Forest, IL and at Southern Methodist University in Dallas, TX. I love this place. There is always something new to learn and the patients are fascinating. Our team is awesome and they are really more than just a team. Over the years they have become my family. As a matter of fact we have several family traditions going here. Jana and Lindsay are mother and daughter, and of course I am “married to my job,” having worked with my husband now for over 27 years. I wouldn’t have it any other way. We always celebrate each other’s birthdays, weddings, anniversaries (and sometimes divorces). Everyone on staff who has children has had one or more of them work in our office at some time or another. Who says you can’t pick your family!

Nakos Kotsanis

Micronutrient-Phytochemical Anticancer Researcher

I am here to keep Dr. Kotsanis well informed and scientifically documented thru Pubmed articles concerning integrative medical literature. Due to my scientific interest in Vitamin C and cancer, I have the contacts that I make with great scientists who are experts in Vitamin C research and its usefulness in health and medicine, i.e. Dr. Hickey, Dr. Lawson at Oregon State University, Dr. González-Guzmán, Dr. Levy,  and of course Greek scientists that support us. I also advise and inform with the guidance of Dr. Kotsanis’ people, who with their consent, would like to learn on how to prevent or approach adjuvantly an illness such as cancer through our Actouarios Nutritional Therapy (research and anecdoctal observations).
In addition, I give talks on behalf of the Institute on integrative medical to doctors and scientists and “open to the audience” seminars to make them understand the usefulness of micronutrients and phytochemicals on health and quality of life.  I also continue updating the Actouarios protocol according to recent scientific data – patient’s feedback – personal contacts so as to exchange ideas apart from the literature research that never stops.
I believe in keeping us internationally known and to make the public here in Greece become aware of the effort and dedication that my mentor, Dr. Kotsanis, has been putting into integrative medicine the last 30 years.  For me it is a great honor working beside him.

“Excellence is never an accident. It is always the result of high intention, sincere effort, and intelligent execution; it represents the wise choice of many alternatives – choice, not chance, determines your destiny.”
