    Philosophy of Care

    My goal is to partner with patients to address their unique health care needs. I think it's important to give patients as much information as possible so they feel empowered to make decisions right for them. I really enjoy practicing endocrinology since it allows me to follow my patients over time. I try to keep current with the latest medical findings, so I can offer the most advanced diagnostic and treatment options.
