18 Years of Experience

I joined Beacon FS Ltd. in 2003 and began working on the Retirement Plan side of the business under my mentor Dan Barbiero. For nearly 17 years, my primary focus has been on the ever-changing landscape of Employer Sponsored Retirement Plans as well other employer sponsored benefits. In October of 2021, the founders of Beacon FS Ltd, Dan Barbiero and Tom Eschmann retired, and I partnered with Michael, James and Craig of ICG next, a next generation wealth management firm, to establish Beacon ICG LLC.

I enjoy spending time with my wife (Winn), children (Owen, Theo & Maeve) and extended family of brothers, sisters, nieces, and nephews. I love to travel and enjoy fishing, kayaking, skiing, cooking and a good craft beer.
I am an active member of St. John’s Church in Cold Spring Harbor, where I serve as the Sr. Warden for both the church and our historic Memorial Cemetery. I’m also active with our local youth sports leagues as a supporter and coach.
