When I was living in Maui after college I discovered yoga, meditation , and the healing power of food and the outdoors. I truly saw first hand how this type of lifestyle has the power to create a healthy, vibrant community. I knew I needed to find a way to share this with everyone, because with the right tools and support, people can heal naturally. I investigated different ways of how I could do this in my career and ultimately went to medical school in order to get a basis in the hard science of Western medicine, so I would have the knowledge of everything from pharmaceuticals to therapies to procedures. It’s good to know how to recognize what needs to be addressed from a conventional medicine point of view and be able to work within that framework.
I frequently see people with autoimmune conditions, gastrointestinal disorders, adrenal thyroid , hormone imbalances, trouble losing weight, fatigue , or people who are looking to prevent health issues down the road. I also see a fair number of very nuanced cases – where people have been to many doctors who have found no physiologic reason for their concerns. These are some of the most rewarding cases for me because often the patient has searched for years for a solution and they’re just so grateful to have a doctor that will spend the time with them to find out what’s going on.
I love that Parsley Health is making functional medicine more accessible to people. The year membership model is also an ideal way to work in a functional framework. On the tech side, the transparency and continuity of care was appealing.
So many! Before practicing functional medicine full-time, I taught medical students and residents in a university setting, so you could say I’m a little bit of a science nerd! I’m constantly reading the latest studies on chronic disease and going to conferences where I can expand my skills and learn from other doctors and researchers in the healing fields. I’m particularly fascinated by the interactions between our environment and ourselves – including germ theory, the exposure, and the microbiome and its impact on our health. I’m equally passionate about the current practices and history of women’s health, pregnancy, childbirth, childrearing, and the ever changing practice in cardiology, metabolic medicine, and the physical manifestations of emotional trauma as well as the power of the mind-body connection.
I began in a conventional family medicine model where good intentions are met with barriers at almost every step of the patient’s and the doctor’s experience. It should not be so hard to practice and communicate good medicine and wellness in the community. The complexity of medicine should be in biochemistry, physiology, and the interplay of the psycho-social-biological state, not in trying to get testing and treatment done or meeting patients’ needs.
Close. It’s truly and honor to be able to meet people in this way-to be a guide and support a person trying to live their best life.
Definitely chocolate. Or maybe avocado. Smoked salmon. Macadamia nuts. Pickles. Fresh strawberries. Frozen blueberries. Roasted cauliflower and leeks. Now I’m hungry!
Remember that everything’s gonna be alright.
