The current US Ambassador to Georgia is Richard Norland. Though it may have been his wife, Mary Hartnett.

Importantly, this guy has a serious bio, including assignments as Political Officer at the U.S. Embassy, Moscow; International Affairs Advisor/Deputy Commandant at the National War College; U.S. Ambassador to Uzbekistan; Deputy Chief of Mission at the American Embassy in Kabul, Afghanistan; Deputy Chief of Mission in Riga, Latvia; and Director for European Affairs at the National Security Council, etc., including the Middle East and South Africa.
Importantly, he also worked at the huge, $100m intelligence gathering center in northern Afghanistan at Mazar-e-Sharif, (that spies on Iran, Turkmenistan, Uzbekistan, Tajikistan, and China. Spook central.)
The source I sited in the 1st comment called the Deputy Chief of Mission Bridget Brink an "acting ambassador". Probably they made a translation mistake.
