I believes strongly in our body’s innate capacity to heal, and as a naturopathic physician and midwife, I feel that it is my role to guide this process with minimal intervention. I utilize therapies that support the body’s capacity to heal, including nutrition, botanical medicines, lifestyle changes and homeopathy. I also realizes there are situations when greater intervention is needed and use pharmaceutical drug therapies when necessary. I am comfortable managing patients on multiple medications. I believe that as individuals, we each have the greatest control over our own health and wellbeing, and I see myself not only as a physician but also a coach, motivating and empowering my patients to prioritize healthy choices.
A strong background in biology, chemistry and research, balanced by a firm belief in the innate wisdom of the natural world, guide my practice of pediatrics, women’s health and reproductive health, including fertility treatments, preconception health and care through pregnancy and childbirth. I also specialize in primary care for children with behavioral disorders including ADHD, working with a network of local specialist providers to find solutions that allow balance and success for these children.
I am currently accepting new primary care patients (adult and pediatric), birth and prenatal clients, and adults with ADHD.
