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.  A native Houstonian, he returned to Houston in 1992 after spending more than 10 years as Sales Manager in the Midwest, Northeast & Southwest USA for commercial building products divisions of two Fortune 100 companies – Armstrong World Industries and the General Electric Corporation.  After spending nearly three years as a Top 10 producer with the Grubb & Ellis company, 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.  During his sixteen years as a licensed commercial real estate professional, 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 been one of Colliers’ Top 10 producers consistently throughout his career and was named a “Heavy Hitter” by the Houston Business Journal. He previously served as the President of the Houston Office Leasing Brokers Association (HOLBA) and in 2003 earned his SIOR designation from the Society of Industrial and Office Realtors. 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 live 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.”
