Office Visit
Thank you for the privilege of providing care for you. We hope that the information on this page will help you understand and prepare for your office visit, as well as assist in giving you a better understanding of your gastrointestinal problems.
An important part of our evaluation is obtaining significant information about you and your medical history. If you are a new patient please see our new patient packet (for Dr. Zachary or Mandi Barnes) and return the New Patient Info Form to our office prior to your appointment. If you have not been seen in our office for more than three years, we also request that you fill out the New Patient Info Form and bring it with you to your appointment.
To prepare for your visit you may want to consider viewing the Clear Communication – Talking To Your Doctor video or webinar by Dr. Drossman on How to Make the Most of Your Doctor Visit.
