Jeff Angehrn

Senior Construction Engineer

Jeff’s building career began in 1995 and he’s simply one of the best when it comes to complex structures; it’s been said that he’s memorized every detail of every sheet of every project he’s worked on. Plus, he’s repeatedly recognized by his teammates as an exceptional mentor. He holds a BS in Construction Management from Central Washington University. Off the jobsite, Jeff’s an adventurous spirit who enjoys time with family and friends, traveling, boating, snowmobiling, off roading, fishing, and hunting in the remote wilderness.

Janine Messina

Marketing Manager

CPSM

Janine feels at home in the world of marketing since it combines her passion for art, writing and graphic design with her natural ability to organize, strategize, and analyze. While she enjoys her day-to-day responsibilities, facing new challenges, and the many opportunities to apply her creativity, her favorite part about her job isn’t even marketing-related; she loves working with people and getting to know everyone in the company top-down—from estimating to IT to the hundreds of hard-working craftspeople out in the field.

Amy Bergman

Project Executive

With GLY since 1999, Amy has managed projects in all sectors and of all sizes. This versatility is what helps her guide teams in keeping the end goal in mind while addressing day-to-day challenges and complex problem-solving. She is an alumnus of the University of Washington with a BS in Construction Management and Minor in Architecture, has served on the board of her local YMCA, and is active in NAIOP and CREW. After work, Amy chases two very active children and the lifelong task of home remodeling.

Cassie Withrow

Executive Administrator+Administrative Services Manager

Excellent customer service comes naturally to Cassie, who approaches every task with a can-do attitude. As Executive Administrator, she enjoys working with people that encourage her and test her limits but allow her to have fun along the way. She manages her time—and many others’—with extraordinary ease and keeps things running like a well-oiled machine. Outside the office, you’ll find Cassie hiking, exploring the city, and when the sun comes out, boating on Lake Washington—all with her husband and pups by her side.

Annika Gaffney

Human Resources Director

With over 20 years of experience spanning construction, retail, and hospitality, Annika has mastered the art of building and maintaining a positive, inclusive work culture that fosters employee well-being and engagement. Holding a BS in Business Administration with an emphasis on Marketing, Management, and Entertainment from the University of Montana, Annika brings a blend of creative problem-solving and innovative strategies to her role at GLY. When not at work, she can be found enjoying the outdoors, attending concerts, or cheering at sporting events. Growing up playing softball and spending five years managing, assisting, and playing on the company coed softball team, Annika knows how to bring people together — both on and off the field. As the youngest of six, her experience with juggling multiple personalities is put to good use in HR! Annika is also a proud supporter of Sawhorse Revolution, the AGC Education Foundation, and JDRF Beat the Bridge.

Jon Friedrichsen

Project Executive

HCC

Jon attributes his appreciation of craft and hard work to working as a carpenter for a Spokane-based general contractor while earning a BS in Construction Management from Washington State University. Since joining GLY in 1999, he’s honed his expertise as a healthcare and high-tech office project manager and team builder. When he’s not piecing together complex logistics plans, you’ll find Jon cheering on the Seattle Sounders or casting a line. If he could talk his wife into selling everything and living in a trailer down by the river, he’d be there already.
