    David Peterson, APRN, ND
    Family Nurse Practitioner located in Boynton Beach, Palm Beach Island, & Port Saint Lucie, FL

    David Peterson, APRN, ND, is a family nurse practitioner at premier wellness center PharmXhealthOne, with locations in Boynton Beach, on Worth Avenue on the island of Palm Beach, and in Port Saint Lucie, Florida. David has over 20 years of experience in diagnosing and prescribing treatment plans for infants, teens, adults, and geriatrics with a wide range of conditions.

    Graduating as a registered nurse in 1992 from Florida International University, it only took three years of work inside South Florida's hospitals to convince David it was time to become a nurse practitioner and take (some) control of prescription healthcare. He got his master's degree from Florida Atlantic University as a member of the Nursing Honors Society in 1997.

    Since 1996, David has specialized in Age Management and Integrative Medicine. Finding his niche in interventional endocrinology, David believes a big key to health is bioidentical hormone replacement therapy (HRT). This is a prescription dose of growth hormone, testosterone, estrogen, and progesterone, as well as thyroid, adrenals, and other hormones.

    David was trained in longevity therapies by the American Academy of Anti-Aging Medicine; in immunology by Russell Jaffee, Ph.D.; functional medicine by Jeffrey Bland, MD; as well IV nutrition by Drs. Wright and Gaby. With his extensive experience, David understands the scope of treatment involved in building a regiment that incorporates multiple elements of advanced, prevention-based health care. He has also prepared multiple instruction documents addressing specific patient concerns in this area of medical care.

    David believes the best strategy to promote personal health is to instill a sense of responsibility for people’s own health. The United States Public Health Service promotes the Healthy People 2010 program with an emphasis on prevention, rather than just treatment, of health problems.

    This is “health-care focus”, not “illness-focused care” – the time for health care to move beyond merely saving lives.

    Family Nurse Practitioner located in Boynton Beach, Palm Beach Island, & Port Saint Lucie, FL

    Sandra Mannon, APRN is a family nurse practitioner. Sandra has almost 30 years of nursing practice with an array of experience. Sandra has experience in the nursing field working with infants through older adults. She has practiced in acute and chronic care and now enjoys her focus on preventative care, identifying and managing health issues using a holistic integrative approach.

    Sandra graduated from Nursing School in 1992 and began practicing in a level I trauma center in the Intensive Care Unit. Her focus was critical care medicine for 20 years. She was the diabetic educator in the intensive care unit. She was a preceptor for new nurses and educated the staff teaching Basic and Advanced Cardiac Life Support and Trauma Nursing Core Courses. Sandra returned to school to achieve her bachelor’s in science-Nursing from the University of Phoenix and her master’s in science-Nursing from Concordia University, Mequon, WI. Ten years later she returned to school to complete her doctorate in nursing practice-Leadership graduating from the University of Wisconsin-Milwaukee. Sandra believes strongly in education. She is a professor at Nova University teaching in their master’s in science-Nursing Program.

    In 2018, Sandra decided to focus on educating her patients to learn about themselves and to get into the right mindset to begin living the life one desires. A life of wellness instead of illness. For those with chronic disease, the focus is working together to identify the aliment and learn techniques to regenerate and rejuvenate to a healthy life. Her focus has been on helping others with their weight loss journey as she has been on that journey herself. She has helped many patients achieve and maintain their weight loss goals teaching them the importance of diet and exercise. Sandra is a certified Yoga Instructor and teaches Yoga classes with many of her students being her patients.

    “I want to be a part of my patient's life, build a relationship of trust and understanding so that together we can set goals that will achieve a long-lasting life of great health and happiness.” I lost my father to diabetes at age 56 so I am very passionate about educating individuals on how to prevent diabetes or if you have diabetes how to manage the disease or overcome the disease. Many people believe that once you are diagnosed with diabetes that is a lifetime diagnosis, but it does not need to be. With education, an individual can learn how to manage the disease through diet, exercise, behavior modification, and medications if needed.
