Licensed in DC, MD & VA

Tricia began her professional career as a producer of affiliate relations with CNN. At that time, CNN was a fledgling news organization, so it took considerable negotiating skills to convince stations to cooperate with the network in the daily newsgathering process. Over the next ten years, Tricia’s successful negotiations helped build one of the news industry’s strongest affiliate networks.

After moving to Washington, DC, Tricia refocused her communications talents while representing one of the world’s finest companies: Four Seasons Hotel. As Director of Communications and Public Relations for more than a decade, Tricia established several charitable and community outreach programs that continue to this day and benefit a broad scope of people.

While working in the private sector, Tricia dabbled as a real estate investor and finally turned that avocation into a vocation in 2005. Working with the esteemed McFadden Group, one of the nation’s top real estate teams, Tricia has put her well-honed negotiating skills and attention to detail to work representing buyers and sellers in numerous successful transactions.
