I'm a naturopathic doctor, and full-time faculty in the School of Naturopathic Medicine at Maryland University of Integrative Health. Although my family has been in the health professions for four generations, I didn't think it was the choice for me until I found naturopathic medicine. Being a naturopathic doctor (ND) allows me to be a detective, a scientist, a clinician, and a nature-lover all at once, and it gives me diagnostic and treatment tools that I didn't know existed before I did my training.

Early in my career, I discovered and fell in love with a couple of novel treatment modalities - fecal transplant and helminthic therapy - that are incredibly powerful and massively underutilized. I work almost entirely with patients with hyper-inflammatory, autoimmune and gastrointestinal conditions, where these novel treatments I love can be amazingly helpful, so I think and talk about them with more patients than not.

I treat adults and children with inflammatory bowel disease (IBD) and occasionally other digestive conditions at Capital Integrative Health in Bethesda, Maryland. I also establish doctor-patient relationships in Portland, Oregon a few times per year because of the broader scope of practice I have there. I'm licensed in California, and can provide care to California residents (including ordering labs and imaging) without an in-person meeting.

I offer remote educational consults for people who can't travel to see me but who want (typically) one or two consults regarding medical issues that I have clinical expertise in, like fecal microbiota transplantation or helminthic therapy. I'm often working with your local doctor on this one.

There's a lot of low-hanging fruit where traditional world medicines and evidence-informed medicine overlap. This neglected place is where I like to spend my time - with my patients in Maryland & Oregon, with people who book remote educational consults (all over the world), in non-profit & corporate consulting, and in my writing & lecturing.
