    A few weeks prior to my visit, my 20 mg twice a day Omeprazole need to be renewed. The Costco pharmacy couldn't get a hold of Optum for a week. I then sent in a request for a refill through mychart. My refill was refilled right away, but for 40 mg twice a day, not 20 mg twice a day. I was taking double the dose for a whole week. I then got a notice for my pharmacy that a new script was ready. This time it was for the proper amount. The Costco pharmacy and my husband and I were VERY concerned that Optum never notified us of the major screw up. When I brought it up to Mary, she knew nothing about it and didn't seem to care.

    I really appreciated how well Mary listened to my concerns and answered my questions. She is very personable and makes her patients feel heard and valued. When I had my first visit in the office, the staff in that department were also extremely professional and Compassionate.

Providers must discuss how patient's lifestyle, culture, and goals contribute to gastric health. It is a privilege to work closely with patients in order to build a succ

    Philosophy of care
