Dr Barnett is extremely professional. I appreciated how he gave me options to consider. He also took into account a variety of factors in the treatment plan. I never felt like I wasn't a part of the process. He seems to care about his patients as opposed to patients concerns being a burden. I'm happy he's part of my team.
