Our aim is to deliver individualized, attentive care to our patients. We also constantly hone our skills so that the services we offer are state-of-the-art. In addition to running a busy office and operating room schedule, and assisting other physicians in their training, we highly value and thoroughly enjoy patient communication and interactions. We take great pride and enjoyment in our many patient relationships, some now several decades old. We will always make time to sit with you and listen to you. 

Some of our patients, especially our younger ones, prefer to be seen by a female professional. For these patients, appointments are available with our certified nurse practitioner, Alyssa Larimore, or our certified physician assistant, Diane Gaspar.
