25 Years LogoCongratulations to the Odyssey Team for 25 Fabulous years!

Mike SweatThe ride hasn’t been without an occasional speed bump, but I’m proud of what the company has become and achieved.

When Mike Prisco and I started Odyssey, we believed that there was a better way to do business. As former Government employees, we had been customers of existing advisory and assistance service (A&AS) companies; that turned out to be an advantage for us.

We committed to three ideas: to provide the best available talent; to be more connected to our clients; and to make it easy for our team partners to do business with us. These things fueled our growth, and these same ideals are relevant and apparent in the company today.

Laptop w/logosWhen we started in 1997, some things were easier. I remember hiring only people we knew personally in the beginning. At the first few holiday parties and summer outings, we knew not only every employee by name, but also their spouses and children. I remember years later meeting someone at an industry event and asking what company he worked for, only to learn he worked for Odyssey. Talk about embarrassing!

I remember doing invoices on Saturday mornings at a secondhand kitchen table in a spare room at our house. Mike Prisco would similarly be doing security or HR work at home on nights and weekends. Our first corporate staff members were Gina Prisco, who did our bookkeeping, and Rita Sweat, who took over HR duties. It made for some interesting managerial challenges, but we made it work.

Fast forward to 2015 when I left the company, it was a far larger and more complex enterprise. One of my happiest moments was being able to sell the company to a team of existing loyal and hard-working key Odyssey personnel who I knew would be able to push the company forward without the inevitable staff reductions that would have accompanied a sale to or merger with another firm. That team has made some key improvements including diversifying the Odyssey portfolio into new, exciting areas.

I have kept up with the company’s progress and take great pride in all you have accomplished. A business of this size will always face challenges. The key is to surround yourself with the best people, treat them right, and operate with integrity. The sky is the limit, and I am confident the next 25 years will be very bright!
