Mary Halls, AE & Aesthetic Clinical Director

Mary’s main passion is giving back to what has been so good to her…life. Working on such an intimate level with patients is such an irreplaceable experience. She acknowledges what a privilege it is to be able to touch and heal in so many ways. It is such an honor for her to assist someone in transforming their skin. Mary has trained in the medical esthetics industry since 1996 and still retains her passion for skin care. When setting up the clinic, her main intention was to create an environment that was both nurturing and sophisticated; a place that would be a true reflection of all of us who have chosen to make this their work environment; a place where the true love and compassion we all feel for our patients washes over you the moment you walk through the door; and most importantly a place where you can transform your skin and celebrate your journey.
