I was surprised not to see Emerson on your list. SUNY Purchase has good technical theater as well (or at least they used to).
Also…a huge reach, but Yale has many theater options.
You need to go somewhere where you will be able to get a LOT of training and experiences in the technical theater area. That experience is really the key element (disclaimer, in the 70’s and 80’s my DH was a freelance theater technician in NYC specializing in lights and sound…he had no college degree, but tons of experience, and got all of his work via word of mouth recommendations at the time). It’s the experience you need to look for!
