This is how we found our child's therapist:
Go to psychologytoday.com
Enter your insurance company and your zip code
Enter what you are looking for (depression, anxiety, codependency, whatever).
Not sure if you can enter that you are looking for a male therapist.
But, many profiles will pop up, and you can ignore the female ones.
Many will say they are not taking new patients.
Contact several that do Not say they are not taking new patients, and hope one gets back to you with a schedule that will work for your son.
Good luck!
