Patients are de-identified for confidentiality and patient privacy.October 29, 2024ORTHOPAEDICS CENTERChalmers was exceptional in explaining possible treatment and making me feel confident in what he was saying. His staff was super helpful & so kind. They truly went above and beyond
October 29, 2024ORTHOPAEDICS CENTERCannot thank Dr. Chalmers enough for getting back to full function after surgery. I was in so much pain before and it's amazing to be able to work out and do the things I enjoy again nearly pain free.
October 29, 2024ORTHOPAEDICS CENTERDr. Chalmers is knowledgeable and kind when working with you. He takes time to explain that is going to happen and answer your questions.
October 29, 2024PRIMARY CHILDREN'S MEDICAL CENTERDidn't love his bedside manner. Made it seem like I didn't have many options and then looked at me as if I was dumb asking more questions.
October 14, 2024ORTHOPAEDICS CENTERDr Chalmers is a great doctor and very compassionate. Came to him after another surgeon wanted to take me to the OR and only take care of part of my problem. Since I play sports, I wanted to make sure I'd be able to play and improve afterwards.
October 13, 2024ORTHOPAEDICS CENTERDr. Chalmers is a fantastic physician. I drive down from the Logan area to slc because I trust Dr. Chamlers. His bedside manner and the way he gives all the information to make a decision as a patient. My husband and my daughter have both been seen by him. I work in rural healthcare and I tell people if they need to get their shoulder looked at to go to Dr. Chalmers.
October 13, 2024ORTHOPAEDICS CENTERHe is a wonderful doctor.
October 12, 2024ORTHOPAEDICS CENTERDr. Chalmers is the best surgeon. I have received excellent care from him and his staff. I'm grateful.
September 30, 2024SOUTH JORDAN HEALTH CENTERI feel like I am with the best doctor that can do this surgery. He is always face to face with you when he talks to you about your health.
