Independent Electrical Contractors – Rocky Mountain (IECRM)

Tanner and Jeff were a joy to work with during our selection process. They helped our organization maneuver the decision making between lease vs. purchase and collaboratively and effectively worked with us, listening and responding to our needs all along the way. We are excited to be in our new office location and are pleased Benchmark Commercial was part of the process.

Marilyn Akers Stansbury, CEO - Independent Electrical Contractors – Rocky Mountain (IECRM)


K2 was expanding and opening a regional office in Denver. We had a specific need for a central location, open and configurable space, showers and a vibe that promoted a spirit of creativity. Jeff identified several properties that could work and we narrowed the selection to our top 3 to start negotiations. When the negotiations regarding the lease fell apart for our first choice we decided to look at the market again. This time we found even a better space to fit our company. Throughout the process, Jeff kept us on track while working with our team in Denver and our executives in Bellevue (Seattle). I’m pleased to recommend Jeff and will definitely work with him again.


McCarthy Building Companies, Inc.

Jason was great to work with on finding office space in the Denver Metro area. Not only did he listen and stick to what our criteria was for our office space he was able to provide guidance throughout the whole process. I always felt Jason was looking out for our best interest. Very knowledgeable on locations and availability. Not only was the process smooth it was also fun! I will definitely call when we relocate offices in the future. Great attitude and ability to work with his clients, as well as professional and friendly.

Colorado Enterprise Fund

We have used Tanner for a number of transactions, and he makes each transaction a simple process. We came away from each deal feeling that with Tanner’s help, we had thoroughly explored our options and we understood how to leverage various aspects of our deal to improve our outcome. Tanner is great to work with. I have recommended him to others dealing with the challenge of commercial real estate and will continue to recommend him and Benchmark.

Q Software

Tanner did an excellent job in finding our new office. He took the brief well, produced a short list in a couple of days, and then drove me around on the tour. Since I was new to the office market in Denver, his knowledge and understanding were invaluable. His advice on the final negotiations was invaluable. I enjoyed working with him, and the result was excellent.

Mike Ward, CEO - Q Software Global Limited


We have worked with Tanner for 8 years through several leases and each experience has been outstanding! Tanner is a true professional with high integrity. Our business prides itself on selecting talented advisors and Tanner has always delivered. Tanner is highly communicative and provides explanations in layman’s terms for every detail. We always feel we are being represented in the best possible way. I would highly recommend Tanner and his team.

Chris Smaldone, CEO - Spotlight

Jeff and Tanner did a great job (as always!) helping us go through the process of finding our new space in Golden.

Jason from Benchmark patiently helped us get into our first office space. As tough as it is getting a quality office space in Denver in this market, Jason knows the lay of the land and fitted Denver Institute for Faith & Work’s needs with what was on the market. I’m grateful to God for providing Jason at just the right time.

Integrity Electrical Solutions

Everyone is so excited [to] take possession of our new space… I want to thank you for all of your help in finding the perfect space and negotiating our lease for us. You saved me an incredible amount of time and brain damage not to mention the fact that you negotiated a much better price than I ever could have myself. All at no cost to me. Amazing! I have and will continue to recommend you to everyone I know that is looking to relocate.

Chris Cumpton, President - Integrity Electrical Solutions

Bradley Consulting Group

We are extremely pleased with Tanner and Benchmark’s assistance with securing our new space. We are experiencing growth, needed flexibility with regards to our space, and wanted a great environment for our people. Tanner is a great listener, is solution-oriented, and a strategic thinker. When you consider that he is exclusively tenant/buy side representation, it became logical—do business with people you trust and people you like. I whole heartedly recommend Tanner.

Brian L. Wagner, CPA, MBA, CGMA - Bradley Consulting Group

Burnham Law

I have worked with Jason on several leases, often in expedited timeframes, and he was utterly relentless in both advocating for the best lease/term in each scenario. He was tireless and always available. I now have 4 offices throughout COLORADO and Jason is the only person I trust to get the job done.

Todd Burnham - Burnham Law

Polar Field Services

We are set to move into our new space this weekend. The build out turned out even nicer than I imagined it would. I would like to thank you for all of the help you provided to me to obtain this new space. I appreciated how easy you made it for me by finding numerous spaces for me to look at initially. And even more than that I appreciated your guidance and expertise in working with the landlord once we decided on a space to negotiate on my behalf. That part of the process is awkward, and it was a real relief for me to not have those discussions directly. You did a wonderful job of negotiating on my behalf and representing my interests, and in the end we got a great deal and a really nice space. If/when we are in a position to move again I will certainly contact you, and I would not hesitate to recommend your services to anyone.

Jeff Mason at Benchmark Commercial was instrumental in finding the perfect new office for Aspenware. Before we met Jeff we had been searching for several years to find the right place that reflected our personality and company values. In our initial discussions Jeff made sure we knew he would work hard on our behalf, and we absolutely saw this play out. He listened carefully to our wish list and the limited geography we were interested in pursuing, and he found several options. He helped us develop the vision of what our new property could be and was persistent, professional and diligent in his negotiations with our new landlord to make sure we got exactly what we needed. He also worked with our old landlord to ensure that the transition out of our old space was smooth. We are tremendously happy in our new building and new neighborhood, and our clients constantly comment what a beautiful, inspiring space we have. We’d absolutely recommend Jeff and the services of Benchmark Commerical.

Janet McIllece, Vice President, Consulting - Aspenware

I cannot begin to thank Tanner and his team for all their outstanding efforts. They worked so diligently and did everything in their power to expedite the entire process. The team was always there for me and, in baseball terms, “stepped to the plate” to hit a grand slam for me!! My lasting impression of them is one of ultimate professionalism, teamwork and dedication to its customers. I will always keep you mind for future business and referrals.

Allan Roy Morton, Jr. CIC CRM, Morton Insurance & Risk Management

Benchmark took us through the labyrinth of things we needed to know so that we didn’t get blindsided during our search for new office space. Professional, knowledgeable, and available. We are months past our move and no buyers remorse. We were advised well and Tanner helped us negotiate great terms. I’d highly recommend them.

Lynda Reifman & Jim Williamson, Co-owners of Colorado Property Management Group

Our continuing business relationship with Tanner began more than 10 years ago. During this time, Tanner has worked diligently on our behalf to secure favorable lease agreements for our company. He also shows admirable patience in taking us to view many office spaces and providing options to our current location. Tanner is personable and has consistently demonstrated his commitment to our requirements for CPMG.

Lynda Reifman & Jim Williamson - Co-owners of Colorado Property Management Group

Dennis M. Pade, Co-Owner ExTex.

Over the years we had grown into adjacent space, although not very efficiently. Less than 3 months before our lease was about to expire we talked to Jeff about our options. He learned about our goals and quickly identified a handful of office spaces for us to tour. One of the options had always been to rework the space we were in. We sent proposals out for two properties plus our current space and started negotiations. In the end, Jeff was able to negotiate a substantially lower lease rate with our existing landlord which included all the improvements we wanted for our space. We estimate that we will save at least $100,000 over the next 5 years. We will be happy to use Jeff again and are very comfortable recommending him to anyone else.

Dennis M. Pade - Co-Owner ExTex.

GWD Design

[Tanner’s] knowledge of the commercial real estate market and responsiveness to the unique requirements of our growing company created real value for us. Tanner strategically negotiated on our behalf and achieved significant savings for GWD in both lease and expansion costs. I would highly recommend him as a trusted real estate adviser for tenant services.

Ari Kaufman, CEO, Location Insight

Securing a space that would capture our culture’s creativity, innovation and urgency was our most important goal. We have east-coast-based capital partners and a real estate team that needed to be satisfied with the engagement. Tanner and his team navigated the Denver marketplace very smoothly while working closely with all parties involved. Taking our needs, interpreting our feedback and leveraging his depth of experience brought us to a most unique and perfect location. I highly recommend Benchmark and their real estate results.
