Scouting here at St. Thomas is a great program, but no one can offer “one size fits all” for kids. We share your desire to find a program which matches your son's interests and needs. A scout troop should be a happy "home away from home" and a fun adventure. Over the years, we've observed some trends in the boys who find us to be a happy home. There have been exceptions, of course, but these trends might help as you are looking at programs.
The big rule is that we tend to be a happy home for kids who come and participate frequently. There is often a great deal of synergy between Troop 8 and school, sports, science projects, college essays, and the like, where the troop introduces boys to a subject they persue in other venues, or we give them a practical outlet for the skills the've developed in a more abstract classroom. For us, climbing systems are an application of trigonometry and vector forces, and it's not unusual for troop scouts to give public comment at council meetings or write op-eds for the paper about things like mountain bike access to parks! Our adult and youth leaders are medically savvy, and are good at helping boys and families work with medical conditions like allergies or chronic conditions.
Our adult leaders are happy to discuss your son's interest, and to work with you on helping him find a happy scouting home, either with Troop 8 or with one of our many brother troops in the area.
