Mark McKenna

Performance Health Coach - Cenegenics Alaska

My name is Mark McKenna and I’ve been with Cenegenics since 2013, initially working out of our Boston, MA location. My role involved advising a diverse group of executive-level clients on nutrition, exercise, supplementation, and hormone optimization. I conducted on-site diagnostic testing, including DEXA, Vo2 Max, and Resting Metabolic Rate Testing.

In 2020, I transitioned to our remote team, supporting centers in Alaska, Tulsa, Connecticut, and Washington DC, as well as providing on-site assistance as needed. In recognition of my contributions, I was promoted to Remote Team Lead in 2021.

I hold a Bachelor’s degree in Exercise and Health Science from the University of Massachusetts Boston, graduating Magna Cum Laude. I’m a Certified Strength and Conditioning Specialist (CSCS), accredited by the National Strength and Conditioning Association. Additionally, I’m certified by Precision Nutrition and as a Level 1 Certified Golf Fitness Instructor by the Titleist Performance Institute.

With over 10 years of experience as a personal trainer, my clients have included busy C-suite executives and elite athletes aiming for peak physical condition. I’m here to help you take your health and fitness to the next level.

Everything about my Cenegenics experience to date has been superb. First, I am more than happy to be part of this team and hopefully will be with them for many years. The phone support with the administrative and other counseling points of contact was professional and personable. The first personal contact I had with a member of the team was with my phlebotomist who came to my home to draw blood and urine samples, which was very convenient. The next step was taking a battery of tests (cognitive, dexterity, etc.) performed online in the comfort of my home. I was also able to fill out my present health questionnaire on my PC. The next phase was a lengthy consultation with Dr. Robert Ledda via Skype. Dr. Ledda and I talked for quite a while about my lab results enabling him to analyze where I was health-wise. We agreed on a plan of attack to get me to my personal goals of better overall health and enjoying my longest span of life possible. I’ve been on the program with testosterone shots, supplements, and lifestyle changes and already feel more energetic. Cenegenics is taking care of their area of expertise, and I am taking responsibility for areas that are my concern. I am expecting good things from this partnership and with the help of Cenegenics will make the most of this opportunity.

Marc B. Cenegenics, Alaska

Now a little more than four years after becoming your patient, I have experienced a positive and complete turnaround! I have improved in all areas. First of all, my weight is down 55 lbs. I went from 33% to 15% body fat. I would like to emphasize, not only have I lost weight but based on blood work and testing results, I have improved in all measurable areas as well. No longer tired throughout the day, and when I go to bed, I go into a sound sleep and awake rested and ready/excited to start the day. My thoughts are clear and focused, This is not just my opinion, as others have noticed this as well. My mood and relationship with others have all improved. I now have an understanding of what and when to eat, how to exercise, and why. I could go on and on listing the areas of improvement since I started on the Cenegenics program, but I just wanted to thank you for the effort that I have received.

Scott L. Cenegenics, Alaska

I enjoyed the professionalism of the Soldotna Cenegentics staff. A thorough physical was something I was looking for and appreciate the doctor digging deeper into my health and listening to my concerns and needs to help me address my health issues. Currently involved with more tests and working with me to help me feel better. I will pass this opportunity on to my friends and co-workers. Thank you Dr. Bob Ledda!!
