HOUSTON – Transwestern Real Estate Services (TRS) announces it has been named the exclusive leasing agent for 6624 Fannin Tower by Texas Children’s Hospital. The Class A medical office building, located at 6624 Fannin St. in the Texas Medical Center (TMC), offers an ideal location for all medical institutions and businesses desiring to be in the heart of TMC.

Transwestern Senior Vice President Ashley Cassel Byrd and Associate Justin Davis have partnered to deliver best-in-class leasing services for the 445,725-square-foot property on behalf of Texas Children’s Hospital.

“We are proud to expand our long-standing relationship with Texas Children’s Hospital,” said Byrd. “This asset is iconic in the Texas Medical Center and the Houston skyline, and we look forward to working with the world-renowned doctors that are affiliated with it.”

Fannin Tower currently has several attractive vacancies ranging from small office suites to 60,000 square feet of contiguous space that would be ideal for strong credit tenants that have patients who would benefit from proximity to TMC. In addition, the leasing team will target companies that will benefit from proximity to the life science, research and biomanufacturing communities expanding within TMC and along Houston’s Innovation Corridor.

The property features 24/7 security, valet parking, MetroRail route access, a connected parking garage, a Murphy’s Deli and 360 views of TMC. Current tenants include Baylor College of Medicine, CHI St. Luke’s, Kelsey Seybold, Texas Heart Institute and Walgreens.
