I was a physician for over 22 years and joined the pharmaceutical industry in 2004. So, they call me Doc.  I began playing with rocket toys when I was 10. By the time I was 14, I had been doing black power rockets for a couple of years or so when I found Rocket Manual for Amateurs by Capt Bertrand Brinley. I got immediately into sugar fuel and powdered zinc and sulfur. Back then and for another 3 years I was building rockets with my friends made out of metal airframes and fins. Metal shop, wood shop and electrical shop in high school moved me right along. Things really slowed down in college (BSc, Chemistry), but I always built black powder rockets right through med school. Like so many of my rocketeer friends, we all settled into our professional lives and raising families. And like so many rocketeers, kids grow up and leave home. I was getting itchy back in 2009. My grandson, Gunnar, was 4. He was interested in rockets for some reason, so I bought a couple of Estes kits (Bull Pup and Patriot), and the "torch" was past to a new generation. I was a flight away from a rocket a day. I got on the internet, found high power rocketry, and the rest is history. I built an Initiator from Aerotech and joined the Superstition Spacemodeling Society out of Phoenix, AZ. I brought the rocket to one of the launches one Saturday anxious about my first mid power launch. I bought some little motor for it. I showed it to Dwain Desbien who said I needed something big. He found the biggest 29mm motor he had. "Go big or go home!", he said. I've been living by that motto ever since. Thanks Dwain! Maurice "Moe" Bertrand, whether he knows it or not, has been a mentor from the start, a great friend and photographer for my and many others' launches. This site is filled with his photos. Thanks Moe!  My L3CC Terry O'Brien, former President of the Superstition Spacemodeling Society, and Gerald "Skippy" Meux, Jr have been invaluable moving me to the top of the game. So, the site is dedicated to my grandson Gunnar, my rocket widow Kris, Moe, Dwain, Terry and Skippy.

You have to start somewhere (Aerotech Initiator).
