Proudest Moment

“Crossing the Boston Marathon Finish line for the benefit of the St. Jude Children’s Research Hospital in 2015 as a St. Jude Hero.”

“Shutting it down and taking myself offline. Meditation, music and acupuncture are my go-to tools.”

Energy Booster

“High intensity interval training – either in a spinning class or in the boxing ring.”

Super Hero Power

“When I’m not wearing my St. Jude Hero Cape…I help the Ligris team or friends realize their potential and get them outside their comfort zone.”

Favorite Vacation

“Obsessed with Europe… Barcelona, London, Paris, Athens, Mykonos – can’t get enough. Oh…and Montana!”


“Trying to improve my inconsistent golf swing, working out, attending live music events. Skeet shooting or trap, a good massage, dinner and vino with friends.”

Comfort Food

“Anything Greek or Mediterranean… I mean, look at the name!”

On My Playlist

“You name it! Imagine Dragons, Billy Joel, Coldplay, Snow Patrol, Ray LaMontagne, The Notorious B.I.G., Michalis Hatzigiannis – and starting in November… Christmas Music.”

Why Ligris?

“The firm name had a certain appeal to me ;) All kidding aside, I wake up every morning excited to work with a team comprised of some of the best in our business. We are a big family that takes care of each other and our clients and we live for that.”
