Tyler J. Threehouse, Esq.

Owner & Attorney

Tyler is the owner and attorney at Threehouse Law Firm. Growing up in Allegany, New York, he aspired to be an attorney at a young age. Tyler graduated from Daemen College in 2011, Summa Cum Laude, with a Bachelor of Arts degree in Political Science, and a minor in Psychology and Criminal Justice. After college, he attended the State University of New York At Buffalo Law School, where he graduated from with a Juris Doctor degree in 2014.

After being admitted to the New York State Bar in 2015, Tyler practiced law as a personal injury attorney in Buffalo, New York. As a personal injury attorney, Tyler focused on helping clients through difficult situations as they took the steps to regain their life following a traumatic event or injury. In 2016, Tyler joined Reisner Law Group in Olean, New York, where he shifted his focus to several new practice areas: estate planning, asset protection, and elder law. Since that time, Tyler has devoted himself to serving residents of the greater Olean and Western New York area, and strives to support and give back to the community that has supported him and his family over the years.

In January 2018, Tyler started his own firm, Threehouse Law Firm, which took over Reisner Law Group’s Olean office location. Now as an independent law firm, his firm’s practice continues to focus on helping people and serving our community. Through providing assistance, advice, and planning for our community’s residents, Tyler strives to educate and provide peace of mind to his clients by designing and delivering highly customized estate plans for them.

Tyler prides himself on providing excellent customer service, delivering peace of mind to his clients, and providing a fulfilling place for the firm’s team members to work. The firm’s team-oriented approach and passion for helping its clients allows the firm to develop meaningful relationships with its clients, something that is very important to him.

Although Tyler is very passionate about his career, the most important thing to him is family. Tyler spends most of his free time with his wife and three children, and their dog, Teddy. He likes to spend time doing things with his family, hunting, and spending time at his family’s camp. Tyler also enjoys golfing, playing ice hockey, and cheering on the Buffalo Bills, Buffalo Sabres, and New York Yankees.
