Your full-service,
in-house development team that’s not in-house.

We handle every aspect of bringing your vision to life for you. Starting from the ground up. This includes everything from identifying the ideal location for your project, vetting the right partners for the job—including architect, GC, subs, and more—handling permitting, funding construction draws, financing, material sourcing, surveying, sustainability strategy, community relations, leasing, and more.

When you need the space, we make it happen.

  • What sets us apart is our unique ability to deliver effectively on your vision thanks to the thousands of critical relationships we’ve built over the years with every player in the market.

  • We act as a conduit of information between every part of every project, offering fluid transparency that ensures everyone is always on the same page. No surprises.

  • We ensure whatever space you’re building can grow with your needs, designed to maximize your return on investment for the long run.

  • Thanks to our reputation and connections, the phone doesn’t ring for too long when we call.

  • With age and experience comes unmatched knowledge, negotiation skills, and the ability to plan with your goals in mind.

Take it from our partners

“Working with Travis on our project was unlike any other real estate company we’ve worked with to date. He heard our strategic goals first, and then focused on finding properties that fit that value proposition perfectly. The Sullivan Group is one of the top real estate companies in the city, but flies under the radar, the perfect IYKYK brokerage.”
