What do you like best about helping clients?
I like being relied upon by my clients to provide the answers to issues when they need help – it's also great to know that they appreciate the help and hard work that our staff put into their projects.

After working here for 17 years, it's comforting to know that the overall values of the company have not changed. That keeps me motivated.
What do you do in your spare time?
I travel as often as I can, and I try to limit my travels to places that I haven't been before - both within the United States and internationally.
What's your favorite season?
My favorite time of the year to travel is Summer time - there are so many more options - but Winter is my favorite time of year to be home.
Do you own any pets?
Yes, I have a dog named Lelu.
What kind of music do you like?
I like nearly all kinds of music; it varies depending on what I'm doing and what sort of mood I'm in.
Favorite movie?
My favorite movie of all time is the Fifth Element. In fact, I named my dog after the main character of the movie.
