Tierney was born and raised in Chicago before moving to the heart of New York City. Tierney began her real estate career at a boutique real estate firm. She immediately fell in love with the energetic and fast-paced real estate culture of New York. Working in New York, her passion for real estate quickly brought her success and recognition as one of Midtown Manhattan's top agents. She developed a refined white-glove customer experience and enjoyed building genuine relationships with her clients. After a successful career in NYC, Tierney and her artist husband brought their talents to Detroit. "I see Detroit as a city on the verge of a dramatic revival. The city is vibrant, with so much culture embedded in each neighborhood. Detroit is primed for a real estate boom and I want to play a key role in making it happen," says Tierney. She enjoys novels with a strong female lead, acting in fringe theatre, and going on long hikes.
