About me
I grew up in Fort Lauderdale, Florida, subsequently lived in Texas for ten years, then Chicago, San Francisco, and now Seattle. I consider both San Francisco, and now Seattle, home. I am happily partnered to a wonderful man. We met serendipitously in Chicago, while I was completing a fellowship in child psychiatry. Although we both love pets, we don't have any of our own yet.
About my practice
As long as I can remember, I've been fascinated with the human body and mind, how they work in tandem, and the complexities of biology. I had originally wanted to pursue medical research, but realized early on that what drew me to medicine was patient interaction. Integrated health care delivery is the way of the future, which is why I joined Kaiser Permanente. I believe that medicine is both an art and a science. Getting to know your patients is an art. Applying medical knowledge to deliver care is where the science comes in. My areas of interest are teen mental health and LGBTQ care. I have also participated in demographic research pertaining to bipolar disorder symptoms in children and teens. I love being part of a profession that has ethical and academic standards. Medicine is not only a profession, but a fellowship of caring, intelligent, and creative people who strive to make the world a healthier and more compassionate place.
How I thrive
I love exploring the islands in the Pacific Northwest and taking road trips throughout scenic Washington. My hobbies include tai chi, science fiction movies, current events, and anthropology.

How we choose our network providers and hospitals
Kaiser Permanente uses the same quality, member experience, or cost-related measures to select practitioners and facilities in Marketplace Silver-tier plans as it does for all other Kaiser Foundation Health Plan (KFHP) products and lines of business, and uses the same geographic distribution consideration to select hospitals in Marketplace plans as it does for all other Kaiser Foundation Health Plan (KFHP) products and lines of business. The measures may include, but are not limited to, HEDIS/CAHPS performance, member/patient complaints, patient safety scores, hospital quality measures, and geographic need. Members enrolled in KFHP Marketplace plans have access to all professional, institutional and ancillary health care providers who participate in KFHP plans' contracted provider network, in accordance with the terms of the members' KFHP plan of coverage. All Kaiser Permanente Medical Group physicians and network physicians are subject to the same quality review processes and certifications.
A narrow network is defined as a tailored, tiered, or high-performance network that has 80 percent or less overlap with a health plan’s broadest network offered to a member in any type of plan offered by that health plan. Kaiser Permanente does not have a narrow network with respect to its Marketplace plans. Members enrolled in Kaiser Foundation Health Plan (KFHP) Marketplace plans have access to the same provider networks as members enrolled in all other KFHP plans.
