My son has worked with Randy a couple of times at the Armory. I can't speak specifically for the new facility of course, but our experiences with Randy (and the rest of his staff) have been very good.
It's just an anecdotal example, but my son first visited Randy after completing several months of rehab for pretty bad elbow tendonitis. After a head to toe evaluation and video analysis Randy suggested some mechanical changes, and sent my son home with a written plan for drills to do for the next 3 weeks.
By the time he was done with the plan, my son had added about 7 mph to his velocity - and was throwing pain free for the first time in about a year. So, we're pretty big fans.
