Overview

I joined this General Surgery practice as a new-graduate in 2019, and it has been an honor to care for our patients who present with a wide array of both elective and urgent/emergent surgical needs. My goal is to not only provide exceptional surgical care, but to treat each individual with the compassion and respect that he or she deserves.

My clinical interests include endocrine surgery (thyroid, parathyroid, and adrenal glands), breast surgery, advanced laparoscopy, colon cancer, and gastrointestinal surgery. I am committed to providing the highest quality of care to each of my patients. I believe in pairing my clinical experience and skills with the patients own beliefs and preferences, in order to give guidance for important decisions and formulate a personalized care plan. My patients can be assured that they will receive excellent care, with emphasis on minimally invasive approaches for the fastest possible return to work and family life. I believe that attention to the best cosmetic result after surgery is also very important for patient satisfaction. I strive to treat each patient with compassion and respect, making sure they understand the rationale and expectations for their surgical experience. The multidisciplinary approach for cancer treatment is an important aspect of my practice. Dr. Eden is rated as an Experienced provider by MediFind in the treatment of Colitis.
