About THH Construction

THH Construction was born when the founders saw a niche in the tenant improvement market. They envisioned a construction firm that would provide work of the highest quality while maintaining a high level of personal service and client communication. They founded THH to fulfill that need in 2015. Since then, they have intentionally kept THH as a small firm so that they can personally oversee every detail of every project and provide the level of service and quality to our clients that they deserve.

THH started out with just two partners looking to provide general contracting services that exceeded expectations every time. Now, a few years later, they have brought on some additional key team members: a top-level tenant improvement superintendent and a highly skilled carpenter who share the founders’ values and goals for the company. In the years ahead, THH plans to grow modestly and slowly while never losing sight of its core values and level of personal service.
