Dr. Cox was warm and inviting. He greeted my husband and me with a wecoming hand shake, and he did a thorough check on me as his paitent. Furthermore, his detailed explanations and recommendations are clear and concise. This is my first time visiting the office, but I believe Dr. Cox has great rapport with his patients.
