My medical practice philosophy is that you are the central part of a team where we work together to help you succeed in attaining lifelong healthy weight. I will endeavor to help you problem solve the barriers to exercise and healthy eating. I will push you gently (and maybe sometimes with a little extra effort) to make sustainable, realistic changes. Even if it seems you cannot do it all, I believe there is always some positive change I can help you make.

In addition to routine post-bariatric surgery care, I have deep experience in caring for more complex medical issues following surgery, such as hypoglycemia, malnutrition, renal failure, and the consequences of vitamin deficiencies. I see all patients who have had a duodenal switch outside of Kaiser Permanente and I’m also interested in research on the benefits and risks of bariatric surgery.

I joined Kaiser Permanente Fremont in 2002.

I am originally from Cork, Ireland, and later, Dublin, where I went to medical school. I moved to California in 1997 with my husband who is in the high tech industry. We now live in the Bay area with our two children and dog. We are a very active family and I love running, road biking, swimming, and squash. I strive to teach a passion and love of exercise to my patients. When time allows I enjoy building: shelves, cabinets, anything! I love antiques, old books, and maps. In quiet times, I love to play the piano. I speak Gaelic, reasonable French, and am trying to learn Spanish.
