I began designing and analyzing PMDs under the tutelage of Bob Grove in 1983 at Lockheed Missiles and Space Company, Inc. Bob was the pioneer in the field and I was fortunate to have such a great teacher. When I left LMSC in 1985, Bob already had designed over a dozen different PMDs and had hundreds flying - all analyzed only with a slide rule. After leaving Lockheed, I attended MIT where I received a Master's degree and began provided PMDs independently with Pressure Systems, Inc. For 24 Years, I provided PMDs exclusively with Pressure Systems, Inc. (now ATK Space Systems).
in 2011, PMD Technology became fully independent providing PMD services to all users and manufacturers of PMDs.
In the past 25+ years, I have been fortunate to have had a great number of supporters in the aerospace industry without whom my business would not have done so well. I am sure I will forget somebody important but those whom I am most indebted include Bob Grove, Jim Rollins, Don Kohorst, Mike Hersh, Alex Roberts, Mike Debreceni, Joe Lewis, Tso Ping Yeh, John Ellison, Joe Vas, GP Purohit, Mr. Seki, Mr. Izumisawa, Mr. Yamaguchi, Walter Tam, Gary Kawahara, and Ian Ballinger. Thank you.
