Giancarlo Leone, P.E.

Chief Executive Officer, Principal Engineer

Giancarlo “GC” Leone holds a Bachelor of Science in Engineering Physics, Master of Science in Electrical Engineering (Power Emphasis), and Master of Science in Engineering and Technology Management, all from the Colorado School of Mines. He has been involved in power system engineering since 2004, and his technical curiosity has afforded him opportunities to work in many areas of the industry.
Giancarlo’s vision is “Engineering, rooted in excellence, for the greater good.” He is a champion for the personal, professional, and technical development of SR3 employees; the redefinition of the client-consultant experience; and the stewardship of our abilities for the advancement of the industry.

Much of his free time is devoted to several professional organizations, including IEEE Standards Association, IEEE Denver PES/IAS chapter, CDEGS Users’ Group, and NACE. The rest is spent camping, traveling, and anything else involving family and friends.

Dennis is actively involved in the CDEGS Users’ Group and has served in several roles on its executive committee. He came to the United States back in 2006 with his wife Mila and settled in Denver, Colorado.  Dennis enjoys camping trips with his family and friends, plays a mean game of pickleball, and considers art of photography as a means of communication with the world.

 Nicole Crowe, P.E._

Lead Electrical Engineer

Nicole holds a Bachelor of Science in Engineering with Electrical Specialty, and her Master of Science in Electrical Engineering (Power Emphasis,) both from the Colorado School of Mines. Nicole has experience with detailed substation protection & control design, detailed substation physical design, grounding studies, shielding studies, arc flash studies, distribution coordination (sectionalizing) studies, transmission coordination studies, and AC induction studies.

Nicole grew up in Evergreen, spending lots of time in the mountains of Colorado. Her favorite spot is a little town called Grand Lake where her family spent most of the weekends waterskiing and snowboarding. She is an avid volleyball player and is pretty much ready for a game at all times!

 Andrea Helmig, P.E.

Lead Electrical Engineer

Andrea attended University of Missouri-Columbia, where she earned her Bachelor of Science in Electrical Engineering in 2014. Since then she has been involved in various aspects of the power industry, but she particularly enjoys power system protection, grounding studies, arc flash analyses, coordination studies, short-circuit analyses, and AC interference studies (AC induction).

After spending the first twenty-two years of her life in the Midwest, Andrea left Missouri to be closer to the Rockies she so loves. In her free time, she enjoys all the activities the mountains have to offer.
