Patient Care Philosophy

The doctor-patient relationship is based on communication and responsibility.  I listen to my patients and do my very best to address their concerns and achieve their goals.  My goal as a physician is to give my patients the right treatment for their disease, regardless of what it takes to accomplish this.
