About Us

John Propp Commercial Group, established in 1997, is a full service Commercial Real Estate Brokerage Company located in Greenwood Village, Colorado. We provide a wide range of services and expertise to Owners, Users and Investors of commercial real estate.

Annually recognized as one of the Top 10 “boutique” commercial brokerage offices in Denver, John Propp Commercial Group has built its reputation and success on providing its clients and customers the utmost in professionalism and respect.

John V. Propp, CCIM, has a long history of extensive experience in assisting Owners and Users of real estate. His clients include individuals and corporations both locally and nationally. John has experience in locating, analyzing, acquiring, managing and marketing properties of all types.

John considers himself a “student of the business,” committed to staying on top of his industry. This is proven by him being awarded the coveted CCIM (Certified Commercial Investment Member) designation in 1998. The CCIM designation curriculum is demanding, rigorous, and ranked as the best and most practitioner-oriented education in the industry; the Ph.D. of commercial investment real estate. CCIMs effectively direct local, national, and international commercial real estate transactions.

John Propp Commercial Group is a Realtor Organization®. Surprisingly, not all commercial real estate agents are Realtors. In fact, most are not. To have the honor of using the Realtor name and logo, an agent must be a member of the National Association of Realtors (NAR), as well as a member of their State and Local Realtor Associations. The National Association of Realtors is one of the most powerful lobbying forces in Washington D.C. Locally, the Colorado Association of Realtors (CAR) constantly monitors and influences legislation that affects the business of real estate. Realtors must adhere to a Code of Ethics and Standard of Practice, and are required to submit to mandatory arbitration in matters of commission disputes, thereby keeping buyers and sellers out of the courts. John Propp Commercial Group has been, and continues to be, heavily involved in the Realtor community. We at John Propp Commercial Group believe that by contributing to the success of the Realtor Associations, we are also contributing to the success of our clients. We hope you agree.

John Propp Commercial Group guarantees:

Honesty – first and last!

Responsiveness – Immediate replies to our clients’ requests and quick response times to our potential customers/tenants/buyers. No one likes waiting for a call back.

Professionalism – From a dress code to our record keeping, our customers and clients will always know that when working with us, they are dealing with a truly professional company that takes them and their business seriously.
“Friendly professionalism” is the term we like to use.

Skills – Tons of experience, continuing education and synergy amongst our individuals, all combine together to create a skill set well suited to handle most any real estate assignment. Our sales and negotiating skills are second to none. From offering a simple opinion to coordinating a complex development project, John Propp Commercial Group can help you. Been there. Done that.

Please take a minute to meet the Team.

John’s skills, fanatical attention to detail, extreme proficiency with numbers, responsiveness, patience, negotiation, compassion, assertiveness, diplomacy, CCIM education, and most importantly, sales ability, are perfectly suited to the real estate management business. John is equally comfortable working with the National Corporate Retailers as he is with the Mom and Pop business owners that make up such a large portion of the retail business. As a matter of fact, John is one of the few who truly enjoy the day to day challenges of managing property and people. As an owner of real estate, John has the perspective needed to make prudent decisions that have a positive long-term effect on the profitability and viability of any project. As a landlord, he understands that the main reason for him being there is to service the needs of the customers, the tenants.
