“My approach to patient care is first and foremost to establish the correct diagnosis, taking the necessary amount of time to obtain a thorough history and exam, and through focused laboratory and medical imaging testing. I then work with the patient and referring physicians to establish the most appropriate management plan. I believe that education of patients on their medical conditions is an important part of this collaborative process, and is key to successful treatment and outcomes.”
