Professional Summary

In early 2019, I transitioned from a career in politics and government in Washington D.C. to a career in real estate.  Known for being a straight-shooter, my goal is to provide clients with both creative vision and also the realities that come with doing business in Connecticut. My approach involves extensive market research, industry research, and most importantly asking clients pointed questions.

While a student at The George Washington University I worked on multiple campaigns, interned for Paralyzed Veterans of America in their communications department, and interned in press offices in both the United States House of Representatives and the United States Senate. I graduated from GW with a double major in economics and political science.

My career in politics continued after college – I worked as an analyst on a presidential campaign during the 2016 election cycle. While in Washington, I worked as a research analyst for two government affairs firms and the U.S. Chamber of Commerce – all three serviced Fortune 500 Companies across a wide variety of industries. During Connecticut’s 2018 election I served as Deputy Communications and Policy Director on a gubernatorial campaign.

Over the past 3 years of working in the real estate industry I have discovered that real estate “sales” is more than selling – it involves consensus building with state and municipal stakeholders, assembling a team of industry experts, knowledge of state and municipal regulations, proper attention to optics, and most importantly – asking questions that drive the client to a decision that best suits their needs.

Out of the office you can find me fly-fishing in Connecticut’s rivers and streams. Licensed In Connecticut.
