About Infinity Medical Institute Tampa Florida

Pioneers in Integrative Medicine, Infinity Medical Institute is a company dedicated to bench marking health in concert with breakthroughs in education through science. Understanding where individuals are in their “Life Cycle” as opposed to treating symptoms that are often an expression of a greater challenge they are experiencing with their bodies at the cellular level. A new approach in health and wellness based on recently made available research, allowing us to understand the differences in Biological Age as compared to Chronological Age.

Most of us fail to realize that our personal health is the result of the “aging process” complimented and/or penalized by the manner in which we take care of and/or misuse ourselves. Our consumption patterns combined with normal aging and physical activities directly affect our quality of life.

Our approach to wellness is based on meeting people where they are in their personal life and developing an individualized plan of action in and around nutrition, supplementation, and lifestyle.



“Quality of Life” is the essence of everything we do at IMI. With life expectancies extending longer and longer we hold the key to helping individuals prolong their quality of life indefinitely.

Living, not just existing, is what IMI offers to each and every individual. Life is about experiencing the people, activities and pleasures that mean the most to us. Our life passions are what drive us and give our lives meaning and as we age we should be able to engage and enjoy these passions without limitations.

At IMI we do not take a one size fits all approach with our patients. We identify each individual’s needs and desires and medically customize our therapies to assist the individual in obtaining the quality of life they seek. Not only are we interested in adding years to you life but “adding life to your years…”

“Prior to working with Infinity Medical Institute, I began my journey as a Patient Advocate for HRC Centers in 2011. Little did I know that this role would help me grow in so many ways. I have had the pleasure of meeting so many wonderful people and met lifetime friends. These relationships have helped me grow professionally, spiritually and emotionally.

“Prior to working with Infinity Medical Institute, I began my journey as a Patient Advocate for HRC Centers in 2011. Little did I know that this role would help me grow in so many ways. I have had the pleasure of meeting so many wonderful people and met lifetime friends. These relationships have helped me grow professionally, spiritually and emotionally.

After leaving HRC, I developed the role of a Patient Advocate Coordinator for New Day Vitality (NDV) in which I monitored each patients care and treatment plan. In this position I was the liaison between our medical team, administrative team and patients. I educated each patient as they came into NDV on the importance of having their hormones balanced. As part of growing
both companies, I did a lot of external marketing and educational presentations for medical teams in the benefits short and long term for bioidentical hormone therapy.

It has been such a joyful experience to see the difference in people’s lives as they receive bioidentical hormone therapy. Many patients have been able to reduce or stop their anti-depressants and other medications after they have had their hormones balanced.

I cross-trained in an administrative role in the ICU, CCU, Out-patient surgery and ER for North Arundel Hospital. This position began my interest and passion for treating patients both medically and naturally.

I received my degree in Business Management from Anne Arundel Community College. I have recently moved to Florida and am looking forward to growing my role with Infinity Medical Institute while getting to know the area and meet new friends.”
