    My experience with Dr. Sequist was exceptional. He's a very smart guy and he listens to what you have to say, comes up with very reasonable suggestions. [redacted]

    Dr Sequist is an excellent doctor. He is knowledgeable caring and very efficient! Dr Sequist is always available via Gateway and answers all messages in a timely manner. He always follows up after a visit to check if your new medication is tolerated or if BP readings are within normal range. As busy as Dr Sequist is with his other hospital roles I never feel he doesn't have the time to listen to me. Thank you Dr Sequist !
