Hi, there, and welcome!
Well, Pittsburgh's not exactly a hotbed of great FD vets. I taught a person to hometest who lived over in the area behind that big new-ish mall (whose name I can't recall - not the Waterworks, the other one) off Rt 28 out your way, but her vet definitely didn't qualify.... I can't think of anyone who lives in your area, offhand. I'm in Wexford, but my vet's in Cranberry Twp.) There is a good vet in the Lawrenceville/Bloomfield area, but I don't know if that's too far for you or not.
Impressed that you're already hometesting and have your spreadsheet up!
There are a lot of members in this area. We have an annual get-together at Dian and Wheezer's house in Monroeville/Wall - we'd be delighted to have you come this summer. It's usually in August. Dian posts in the "reunion forum". (Is that still here? It was on the old Board.)
I'll PM you a couple of names and phone numbers....
