Liz Walser was the technician that diagnosed my daughter with severe depression. She eventually became my daughter's therapist and I cannot speak highly enough about what an amazing person and therapist Liz is. She's raised sons so don't let her being female dissuade you from reaching out to her. Her expertise is beyond all therapists we had to suffer through to find the right person. My daughter ended up going back to her while at college after seeing another therapist that wasn't helping her the way Liz did. Liz helps my daughter stay the course unlike any other therapist (and there were lots!). https://www.linkedin.com/in/elizabeth-walser-1b2111176

Best of luck to you and your son.
