RIP Greg Stavish – By Michael Stavish

On October 3, 2022 Greg Stavish passed away at 70 years old. Greg Stavish was at the very first AMMG conference, and also at nearly every one up until his retirement in 2016, when his son Michael took over the family business. Greg Stavish started Insta-Tapes in 1971, and later rebranded to DigiVision in 2006. As a hobbyist and enthusiast audiologist, and a lifelong entrepreneur, Greg invented a way to work with small events to record their sessions, bringing even more benefit to the members that those groups already provide. You probably knew him best as the “Tapes Guy”. When you wanted the conference tapes you went to Greg.

Greg loved his work. He would get excited about advances in technology. The idea of the Internet never occurred to Greg in 1971, but he sure bought in when it came. He was also one of the earliest adopters of video media over audio. But Greg never forgot where we once were. He would fondly reminisce about the old days of tapes and reels, noting that in my short time at the company we’d changed the product five times to keep up, but tapes endured up until 2000. His mind was always churning. He was always looking for ways to improve the product, reduce costs, and add value. He filled notebooks every month with his ideas, and some of them proved the test of time, as they are still implemented at DigiVision today. He never rested. I imagine even his final thoughts were partly what he could still do, for his business and his customers.

He loved his customers even more than his work. So many conference attendees knew him so well. They remembered Greg. They remembered that he would take care of them, but they also remembered his big heart and gregarious attitude. He genuinely liked everybody. Even today, I still get asked, “How’s your dad,” and when I would bring them up later, he’d warmly reflect on them. He loved the purchasers and the conference organizers. He was especially good friends with Rick Merner and Greg Fillmore, having already worked together for nearly a decade before AMMG. He always wanted the best for the group; anything for the success of the group and the conference.

My heart is so heavy, and I miss my dad more than anything, but knowing his life was big and put so much positivity into the world eases the sorrow. I know you will miss him too.
