Any CBT practitioner recommendations for 11 y/o with anxiety?

Hi BPN-ers,

I would love to get  recommendations from other parents for a cognitive behavioral therapist who specializes in children with anxiety. Our 11 year old son has been developing anxiety in a couple of different areas and needs some professional support, but it seems that many of the therapists from the archives are no longer taking new patients or have closed their practices. Any insights with regards to therapists or other resources would be much appreciated. Thank you!
