The Reliable Source reported this morning that Mark Ein, 47, and Sally Stiebel, 27, are engaged...and have been for a few weeks. The pair dated for three years before he popped the question in the Hamptons.
Mark is the CEO and founder of Venturehouse Group, and Sally is a policy analyst at lobbying firm Mehlman Vogel Castagnetti. They are staples on the Washington social circuit, and Mark donates "serious bucks to local charities," as Reliable Source put it.
The news comes hot on the heels of the Kastles second perfect season, which was founded and is owned by Mark. This means his tennis team has not lost a game since 2010.
Perhaps lady luck is on his side.
