Professional Summary

Mr. Parsley has been involved in all phases of the commercial real estate industry including design, construction and architectural for more than 26 years. John joined Colliers in 1999 and is a Principal and Director of the firm. He specializes in leasing office and investments including the acquisitions and dispositions of commercial buildings. Throughout his career he has represented a wide range of public and private companies in the office, industrial and investment areas, including many law firms, energy, financial services and technology firms.  

John has consistently been a Colliers’ Top 10 producer and was named a “Heavy Hitter” by the Houston Business Journal. He previously served as the President of HOLBA and in 2003 earned his SIOR designation. The SIOR designation is a professional symbol of the highest level of knowledge, production and ethics. Only 2,800 commercial brokers worldwide have earned this designation and less than 1,000 are office specialists. John lives by the philosophy of providing the highest level of service to clients, which means being involved in all phases including negotiations, analytical and market research while keeping the client fully informed throughout the entire transaction.

“My partners and I simply want to thank you and your team for all of your efforts and hard work with both our recent relocation (and taking of additional space) and our previous lease renewal. Your expertise and advice made the process as painless as it can be. Your knowledge of the Houston market in general and our complex in particular were invaluable to use in securing the best terms possible. While I am certain we could have negotiated the lease extensions on our own (would any lawyer say otherwise), I am equally certain that the final result would not have been as favorable to us as it ultimately was had Colliers not been involved.”
