“We succeed when we clearly and deeply understand our client’s business, far beyond the technical issues we are here to solve. It sounds simple, yes, and often a step skipped. I’ve found that by going slow up front to align ourselves with the bigger picture, we can gain momentum to the finish line and do so with the certainty that we’re running in the right lane. By working collaboratively within the context of a common vision, we focus all of our expertise toward a singular purpose. That’s our promise as trusted advisors to our clients.”

“For the past 19 years, 98% of my projects have been healthcare projects. What keeps me going is the knowledge that every project I’ve worked on, at the end of the day, has an impact on changing and saving peoples’ lives. You’ll never know what is going to end up on that design table, but it will always affect someone’s family and loved ones. My goal is to make sure that Wood Harbinger provides sound design solutions and creates solutions that enrich people’s lives.

I also enjoy working on healthcare projects because of the fast track nature of technology. I stay up to date on the latest and greatest in healthcare technology to connect engineering to life in unexpected, and forward thinking new ways.”

“I’m way into the details–the project, the program, the potential efficiencies, how all of the building systems relate to each other. I get into the nitty gritty because I care about the facilities personnel who will inherit our designs and will do anything in my power to make sure they receive a system that actually works as intended. Becoming a trusted and appreciated client ally, who serves as a core member of their team, is something I take very seriously.”
