Accountability

Small and mid-sized businesses are seldom represented by large commercial real estate firms because lower commissions often fail to cover overhead costs. TAG holds ourselves accountable for providing smaller businesses with the same expertise that a larger corporation may afford.
Our goal is to represent your business.

Integrity

We hold to an open book policy when dealing with our clients. Our axiom is that directness and honesty in communication are the factors that build client confidence. We communicate all issues upfront, in a straightforward and timely manner, so that you are fully informed during the entire leasing process.
