Personal Statement

♦ Virtual Visit: Delivering the same level of world-class care, with exceptional convenience. 

It is my priority to treat every patient with a personalized and compassionate approach, while striving to offer state-of-the-art treatment options for complex endocrine and general surgical diseases. Understanding the importance of delivering thorough and timely care, I provide diagnostic services during your initial surgical consultation, including neck ultrasound, fine needle aspiration biopsy, and flexible laryngoscopy. If surgery is necessary, I offer minimally-invasive surgical approaches such as laparoscopic and robotic techniques in order to minimize post-operative pain, scarring, and length of hospitalization. Using a multidisciplinary approach to treat these complex diseases, I work closely with colleagues in endocrinology, oncology, gastroenterology, radiology, and pathology to integrate medical and surgical treatment options, as well as to orchestrate attentive long-term follow-up. Lastly, I deeply value advancing diagnostic and treatment quality for patients, which is why I dedicate time outside of the clinic and operating room to actively lead research investigations in Endocrine Oncology and General Surgery.
