    • Sharon L. Caravetta, BSN, MSN, FNP-C


      Sharon Caravetta is a Family Nurse Practitioner with a passion for whole-person care. She earned Bachelor’s Degrees in both Psychology and Nursing and a Master’s Degree in Nursing from Northern Arizona University.When Sharon met with Laura, they quickly realized they were kindred spirits. Their first conversation went on for hours about all of the options and possibilities that exist for patients when providers and patients open up their minds to welcome a holistic approach to care that recognizes the amazing healing power of the human body and views health and wellness as a delicate balance of mind, body, and spirit.To fully appreciate and honor one’s health, the patient must be viewed as an individual with her/his own unique needs.

      This is why she is happy to be at Fusion Medical Care, where she can take the time to understand these needs and incorporate a truly integrative approach to health and wellness, balancing both naturopathic and allopathic care.Sharon enjoys providing primary care services for her patients and particularly enjoys working with patients in the areas of Hormone Balance, Weight Loss, Sexual/Reproductive  Wellness, and Aesthetics.Being so in awe of the human body and the delicate balance required to maintain health is why she is so drawn to hormone balance.

      The endocrine system is one of the most complicated aspects of the human body, and the profound impact that she can have on a patient when she helps them reach a balanced state. This is one of the most rewarding feelings she can imagine that drives her to continue to learn more and work harder.As a person who has struggled with her own issues with weight loss, Sharon is very passionate about helping patients set and reach their goals. It is the plan that must fit the individual, not the individual that must fit all that is unique about them into a generic plan. She has helped many patients reach their weight loss outcomes with a variety of methods designed to meet the patient’s preferences and goals.Sharon feels that one of the most special aspects of being a human is our bond and connection to the ones we love.

      However, many things can hinder one’s balance in this area and be a source of sexual dysfunction, such as painful intercourse, erectile dysfunction, lack of sensation, mismatched libidos, and psychological blocks to intimacy. Her patients feel very comfortable talking to her about their concerns and know that she can provide help in this area, free from judgment and with a sex-positive mentality.Ms. Caravetta has been an aesthetic injector for the past 7 years, and she loves this aspect of her career, as it allows for a beautiful combination of her artistic passion as well as being able to have a profound impact on the lives of others. She strives to achieve natural results for her patients and to feel and look as beautiful on the outside as they are on the inside.Having a background in psychology, she can fully appreciate the profound impact that can be found when one is able to feel better about themselves when an issue in appearance that is bothering them can be improved.She loves spending time with her three sons and one granddaughter. She also enjoys gardening, clay target shooting, yoga, playing cards, board, and video games. Sharon is grateful to be part of the Fusion family and truly believes the best way to create a healthier path is an integrative approach with an open heart and open mind!
