Kleier is head of the high-end real estate agency Gumley Haft Kleier, one of the most prominent boutique agencies in town.

Pittsburgh native Kleier broke into the business working for longtime broker Phyliss Koch. After spending 17 years working for the boutique brokerage doyenne, Kleier left Koch to start her own firm, Michele Kleier Inc. and eventually purchased real estate brokerage Gumley Haft. At GHK, Kleier specializes in uptown pre-wars, although she'll occasionally take a suitably luxe sub-14th Street listing. Unsurprisingly, Kleier has sold property to a slew of celebs over the past decades.
