Therapist for young teen

My 15 year old son is struggling. The isolation and loneliness of the pandemic was bad enough, but then he suffered an injury a couple of months ago that is greatly limiting his activities until this fall. His 2 closest friends have gradually stopped spending time with him and are just hanging out together. He is heartbroken and incredibly lonely. He is usually a happy and upbeat person, very high energy and social. But months of pandemic, lack of sports and friends, being excluded because he physically can’t do many activities right now - is really causing significant emotional pain. I am truly concerned about the next few months - none of these background issues are going to disappear quickly. I think he most needs a chance with new friends, but how can I make that happen? I have tried to reconnect him with his old friends but very unfortunately this is barely working. There are other background stresses too. He acts sad all the time now, or angry and irritable. I know he’s 15 but I’m worried. I’ll take any advice, but I’d most like recommendations for a therapist who works with teens and is within maybe 30 mins from the Rockridge area if possible. Thank you.
