5/5
Dr. Shirman is respectful, attentive, knowledgeable, thorough, ready & willing to work with you to get you the care you need. I have extensive and complicated medical issues. He listens, takes your input seriously, and together we've been working on getting me better, not just stable. I have zero complaints about this doctor! Staff could be better, but that's not under his control. He's a 5 Star!!
