Jill Hughart - Special Projects Project Manager

"Being safe and comfortable is essential for anyone on the jobsite or doing work at home. Utility Pro creates clothing that is durable, functional, and fits a woman’s body."

Jill is a Project Manager who has been in the construction industry for 20 years. She has worked on projects big and small, in fancy offices to jobsite trailers. What drew her to construction was the ‘non-standard’ working environment it provides, being around craftspeople with high work ethics and standards, and the feeling of accomplishment by creating safe and inspiring buildings and environments. She promotes the industry and especially encourages women to enter the field in whatever capacity suits their skills. Empowering women to pick up tools and improve their spaces and their lives is one of her biggest motivations!

Annabelle Cotten - LEED AP | Project Manager

I’m so excited to be part of the Safety Alliance Program and I’m a huge advocate for women in construction! I take every opportunity to tell my construction story and journey throughout my 20+ years in the construction industry. I currently am a Project Manager for Holmberg going on for 4+ years. I’m a mechanical nerd, to say the least, and take every opportunity to be onsite and in the field with my crews. I’m a hands-on PM from start to finish. I’m currently completing a project at JBLM for the USACE (United States Army Corps of Engineers), in the middle of a seismic upgrade for the Navy in Bremerton, and starting a bridge on the Seattle downtown waterfront.

Angela White - Marketing and Public Relations Manager

Angela White - Marketing and Public Relations Manager

I am Holmberg Mechanical’s Marketing and Public Relations Manager. I’ve been with the company since 2012 and one of the highlights of my position is visiting ongoing projects. The sense of accomplishment is swelling when you set foot on a job site. There is an energy in the air of many people working together to create quality work while meeting deadlines and budgets. My sense of safety is heightened because I don’t want to cause an accident while I’m capturing the work on my camera. That’s where Utility Pro Workwear comes in handy. The high-visibility pieces not only look cool, but they fit my body. I don’t feel like I’m swimming in them like other brands. The sleeves hit my wrist at the right length so the material doesn’t interfere with my work. I have a few different options so I’m comfortable year-round in Washington state weather.
