She believes there is nothing to compare to the joy of watching a patient take charge of their health, stop smoking, lose excess weight and adopt healthy eating habits. She sees the patient as a whole. If we can help patients with chronic conditions to adopt a healthy lifestyle, it reduces the negative effects of disease on the body. This requires a partnership between patient and practitioner, and she is committed to doing her part by educating and encouraging patients to achieve wellness. Michelle has extensive training and experience in the area of aesthetics. Along with Dr. Spencer, she created About Face & Body Medical Spa in 2005 offering a variety of aesthetic treatments. She believes it is important for a patient to take care of themselves from the inside out. It’s comprehensive body wellness.
