I've been going to rheumatologist for 44 years. I've never had a doctor treat me with respect, listen to my concerns, work with me, and genuinely want to help me improve. This is my first time actually feeling like my doctor is on my team, and will guide me in the right direction. I'm very hopeful and excited to have a real rheumatologist.
