Testimonials | What Our Clients Say

Robert P. Freeman

Senior Managing Director
Greyfields investors bought Airport Corporate Park through Mercer Oak Realty in 2007. Sab Russo has advised us every step of the way. As an out-of-state owner, we needed a firm that would go beyond the traditional brokerage role and be our advocate. In our seven year relationship, Mercer Oak has more than filled that role. Mercer Oak is our local eyes and ears in the Princeton market. They are a trusted partner in our effort to reposition the property and capture tenants. They are truly invested in the success of Airport Corporate Park.

Jeffery D. Gordon Esq.

Managing Partner
Archer & Greiner has a long history with Mercer Oak Realty. Aubrey Haines has been a trusted advisor and our tenant representative broker since we entered the Princeton market many years ago. Mercer Oak understands our needs, knows this market, and has the relationships that were important for our recent expansion project. We are very pleased with its representation on our new Carnegie Center lease and its continued attention to detail through the planning and construction of the space. We will continue to turn to our friends at Mercer Oak for our real estate brokerage needs.
