Matt Billone


Matt is a highly experienced professional who has built his career around providing innovative solutions to a wide range of clients, such as the Department of Homeland Security (DHS), the Department of Defense Office of the Undersecretary of Defense for Research and Engineering (OUSD (R&E)), and the Defense Advanced Research Projects Agency (DARPA).

A key aspect of Matt’s philosophy is developing a close understanding of each client’s unique needs. Matt strongly believes that anyone with the right qualifications can deliver a solution that meets a client’s requirements, but what makes the difference is actually listening to the client, internalizing their mission and needs, and giving them the best support possible to help them achieve success.

Outside of work, most of Matt’s time is spent keeping his two energetic young children emotionally fulfilled and physically alive. At the end of the day you’re likely to find him passed out on the couch with Wikipedia tabs open on a variety of topics such as the Holy Roman Empire, the culinary habits of ancient Romans, the Andromeda galaxy, and others. In other words, he’s a huge dork.

Sophie Hunt


Sophie is an Administrative Professional with 12 years of experience in administrative management, program management, and proposal management. Sophie spent most of her career in the field of International Development supporting programs in Kenya and Haiti, and managing a home office supporting employees working in Ethiopia, Haiti, Kenya, India, and the Philippines. She took a break from the professional world in approximately March 2020 to stay home with her two children, and was excited to step back in as the Office Manager of Catalina Associates in 2022. Her experience ranges from travel logistics to budget monitoring, business development to insurance administration, and beyond. Sophie has earned her reputation of “cool under pressure”, but she hopes she doesn’t need to put it to good use anytime soon.

Sophie lives in the DC suburbs with her husband and two young kids. She rounds out her chaotic household with two large dogs and two entitled cats, and might secretly go out and adopt a kitten if no one is looking. She spends her free time hanging out with her kids, reading upsetting non-fiction books, and, let’s be honest, cleaning.

Relationships are essential. Catalina believes in building long-term relationships with clients, not single visit deals. We strive to become your advisor and partner of choice.
