Kristen Jefferies Smith completed her undergraduate degree in Nursing from the University of Florida in 2003. She then went on to complete her masters degree in Nursing (ARNP) from the University of Florida in 2006. Upon completing her ARNP, she relocated to the Tampa Bay area where she started her medical career.
Kristen completed her clinical training in the Tampa Bay area with a large internal medicine and endocrinology practice. In that setting, she cultivated a passion for understanding the inner workings of the different body systems and became intrigued by the roles each body system played in keeping patients healthy. She soon realized that she wanted to care for her patients as a whole, not just certain aspects of their health.
After completing her training, Kristen went on to join a large internal medicine practice in South Tampa that included women’s health. In that setting, she cared for a variety of patients allowing her to expand her knowledge base and scope of practice. She then transitioned to a large multi-specialty group in South Tampa where she continue her internal medicine practice in a setting with multiple medical specialties, exposing her to many different facets of medicine.
Although Kristen valued the experience she gained over the past 10 years , Kristen realized there were areas of traditional, “Western,” medicine that are not always the most effective approach to patient care. This has led her to transition to a practice more focused on integrative medicine.
As a Nurse Practitioner, Kristen comes from a paradigm that emphasizes wellness. She is fascinated by the way integrative medicine is rapidly evolving and advancing to bring the most cutting edge treatment to our patients. She believes this area of medicine bridges the gaps in “western,” medicine and allows for more optimal outcomes. Kristen has found that she is able to blend her extensive Internal Medicine background with integrative Medicine to better care for her patients in their totality. She continues to broadener her knowledge base, particularly in the areas of hormones and nutrition and the role they play in improving health, quality of life, and longevity. She is constantly searching for ways to mitigate risk factor which can lead to chronic multi-faceted conditions such as diabetes and heart disease.

Adam’s journey into contrast therapy began in 2023 when he purchased a cold plunge for his home. As he prepared for a bodybuilding competition that summer, he struggled with sleep and sought a natural way to enhance his recovery. This led him to incorporate heat therapy, and the results were undeniable. His fitness tracker showed a 19% improvement in sleep quality on days he practiced contrast therapy. From that moment on, cold plunging and sauna sessions became a core part of his routine, with Adam dedicating himself to the practice 3-4 times per week.
An Ocala native, Adam discovered his passion for fitness at 13 and quickly immersed himself in weight training. He competed in high school weightlifting, became a certified personal trainer while attending Florida State University, and later transitioned into bodybuilding. However, years of intense training led to injuries, including herniated discs, tendinitis, and a ruptured pectoral muscle. Through these challenges, Adam realized the critical role of recovery—discovering that massage therapy, bodywork, and strategic recovery techniques could prevent injury, accelerate healing, and improve performance.
Following his 2015 bodybuilding competition, Adam expanded his fitness approach to include yoga, Pilates, cycling, and circuit training. These experiences deepened his understanding of biomechanics and reinforced the importance of recovery as a foundation for strength and longevity. With this knowledge, he became a licensed massage therapist and founded The Revival Cave to help others heal and perform at their peak.
Now, as a sauna and cold plunge instructor, Adam combines his expertise in fitness, rehabilitation, and contrast therapy to guide others in harnessing the powerful benefits of heat and cold exposure.
