Personal trainer for someone with Rheumatoid Arthritis

I am looking for a personal trainer that has experience working with someone who has Rheumatoid Arthritis and can understand the limitations and knows which workouts to do or avoid. I'm concerned just any trainer might not understand RA limitations and be able to tailor a plan to me.

I'm 37M, live near the Heights and work near City Center so someone in that area would be ideal. I currently go to Planet Fitness so I'll likely need a gym to go to as well.
