Tammy has generously given her time to participate in several industry committees for years, including acting as SAE Aerotech Chair for AEH and the FAA trainer for Do-254. She has visited numerous countries and is known worldwide as an authority in digital hardware design and avionics certification.
Finally, I must comment on Tammy as a colleague. There are dozens of engineers like me who have had their careers supported by Tammy. She is a wise counselor, a standard bearer of integrity and civility, and is as highly respected as anyone in her field.
