Leo, a true professional, family man, and great friend. He and I both hail from the City of Brotherly Love, but attended rival high schools. His school's mascot was the Falcon. So:
"With a Smile on the Lips and a Tear in the Eye
We see Leo, like a Falcon, onto Heaven Fly
Then Bow our Heads, and Bid a very sad Goodbye"

Leo was a friend and mentor to me when I came to the Aircraft Maintenance Division in FAA Headquarters. He was a wealth of information that I could rely on and was always willing to "jump right in" and help. More than his knowledge and experience, I appreciated his friendship.
May God have mercy on his soul and bring peace to his grieving family and friends.

As a fellow Docent, I marveled at Leo’s connection with children. He was great at school tours and I enjoyed listening to him and seeing the children’s reaction to what they were hearing. He will be missed.

Leo was a man of few words, a good man, whose living spoke volumes concerning the respect and goodwill he had toward all people. I offer my condolences to his family and friends.

As a fellow Tuesday docent with Leo for ten years, I learned quickly to respect his knowledge especially when it came to engines. More than that, Leo was a truly nice guy and respected by all. I think I will remember Leo best because of his willingness to do "school tours". He really liked taking a group of elementary grade school kids out on a tour. The kids loved him -- sort of like a "granddad".

Leo was one of the first people I met when first joining FAA in summer 1973. Even as a straight-out-of-college kid I INSTANTLY could tell that here was a guy who what he said you could take to the bank. Even (or maybe especially) if it was not what you were hoping to hear.

God bless him & his family now, just as God blessed us who had a chance to know & learn from him. A gentleman & a professional & certainly an example for when I was a new entrant into "the business".

I met Leo 10 years ago at Udvar Hazy Center when I started as a new Docent. As a stranger and new comer, Leo's trademark smile made me feel welcome. He helped me to get up to speed especially with the engines. Regardless of situations, Leo kept his cool and I can still see his smile coming all the way deep inside. I shall miss him very much. Rest in peace Leo.

He's always been Leo the Great to me, for good reason. He and my beloved friend Bernadette are perfect for each other. So grateful to have known and loved Leo. I have no doubt we'll all see him again. Deepest condolences to all who know and love him, and you couldn't know Leo without loving him...
