Our Integrative Concierge Healthcare Team in Naples, FL

  • Cathryn Mast, MSN, FNP-C

    Cathryn is a board-certified Family Nurse Practitioner with a passion for optimizing physical health through preventative and functional medicine. She integrates conventional medical training with advanced wellness therapies to help patients achieve sustainable, whole-body health.

    Cathryn began her career in the high-acuity setting of the Neonatal Intensive Care Unit at Cincinnati Children’s Hospital, where she developed a strong foundation in clinical precision and patient-centered care. Over time, her focus shifted toward proactive health strategies aimed at improving energy, mobility, and long-term vitality.

    Her current approach uses data-driven insights from functional lab testing to uncover the root causes of symptoms such as fatigue, inflammation, digestive issues, autoimmune problems, or unexplained symptoms. Using this information, Cathryn designs personalized plans that support the body’s natural ability to heal.

    She empowers her patients to move beyond symptom relief—toward deeper, lasting wellness that enhances strength, resilience, and overall quality of life.

  • Chelsea Small, RN, BSN, APRN, FNP-BC

    I’m a south Florida native born and raised. I’m a nature lover at heart which was the catalyst for discovering and utilizing how powerful nature’s medicine can be. I’m a wife to a wonderful husband and a mother to two amazing girls. We love boating, fishing, and riding around Florida’s natural trails.

    I’m been in nursing since 2015 specializing in cardiology and emergency medicine before focusing all of my professional and personal life in functional and holistic healing.

    I know first hand how frustrating getting no answers from every standard medical practice can be. I’ve devoted my professional career to spreading the word and empowering people to shift their own health paradigm when all others gave them no hope.
