Jeff is the President and CEO of AEGIS, specializing in high-end, customer centric security, investigation, training and consulting services. Jeff can still be found in the field managing complex investigations and large scale events when he isn’t busy conducting security assessments, conducting training programs, or managing the day-to-day business of his firm.

In his free time, he spends time with his wife, dog, and close circle of friends, enjoys traveling, riding his motorcycle, firearms training, and exploring other business ventures.
