Bill brings over 26 years of experience to every tenant he represents. Tina, Diana, and the rest of the TAG team each lend their own considerable experience and unique perspectives.
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.
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.
Most of our work arrives the same way: a client we looked after well introduces us to someone they know. We invest in those relationships long after a deal closes, which is why past clients, and the attorneys, accountants and advisors around them, keep calling us back. Read our testimonials and you will see how many of them begin with an introduction.
