Cristhian Mace
Environmental Group

I have had a lifelong passion for the outdoors—for nature and all its inhabitants. I’m passionate about animals; in fact my first word was “fish.”

Following my passion, I went to Cal State Long Beach and got my Bachelor of Science Degree in marine biology and Masters in behavioral ecology and conservation. During college I volunteered at the San Pedro Marine Mammal Center and the Long Beach Aquarium. At this point my focus changed to birds and now I’m an ornithologist.

I’ve been with Psomas for five years and for most of that time worked on the Tehachapi Renewable Transmission Project, a massive Southern California Edison project to replace hundreds of miles of transmission lines. I got to work every day in the Angeles National Forest conducing nesting bird surveys. I was helicoptered to remotes sites and hiked 10 miles in to survey bird’s nests. I hiked in with only a satellite phone, GPS tracker, walkie talkie, and a backpack with food and water. It was paradise.

In addition to nesting bird surveys, I work on construction monitoring jobs, tree surveys and restoration projects. I’m 100% field oriented — I get the privilege of hiking in the outdoors every single day, rain or shine. For someone like me this is a dream job.

Sean Samsel
Project Manager
Transportation Group

Right after graduating from the University of Arizona with my Bachelors Degree in civil engineering I joined Psomas. That was 12 years ago, time sure does fly by.

My team mainly works on major roadway projects throughout Arizona. We also work in Southern California, with our Orange County and San Diego teams. It’s a great example of our One Psomas philosophy, which promotes collaboration between teams in different offices or disciplines. I appreciate Psomas’ teamwork-based environment because I’m a social person and thrive on the constant exchange of ideas and interaction with others.

At Psomas I don’t feel like I’m just a number in a big corporation. The culture is open, friendly and personal. You get to meet a lot of people and you don’t feel removed from top management. I was able to obtain an MBA while working here thanks to advice and encouragement from the head of our Engineering Group, Matt Clark. This personal touch is conveyed throughout the entire company.

One of the best parts about my job is that my colleagues here in Tucson are a close-knit group. We’ve worked together over 10 years and get together socially outside of work. In fact, a bunch of us recently completed a mountain bike race together.
