    Introduction to the
    Owner/User Group A Division of Principle Commercial Advisors

    At Principle Commercial Advisors, the Owner/User Group was created with one clear purpose: to help entrepreneurs build long-term wealth through the ownership of commercial real estate.

    We provide a true concierge-level advisory experience tailored specifically to local business owners who are purchasing, selling, leasing, or operating a commercial property. Unlike many brokerage firms that rely on generalized market reports and broad regional data, our approach is hyper-focused on the nuanced dynamics of individual submarkets.

    We believe that understanding the micro-level details — values, timing, positioning, zoning considerations, and negotiation strategy — is what ultimately makes or breaks a successful transaction.

    Our team specializes in advising business owners who intend to occupy their space, not simply invest in it. That distinction matters. Owner/Users require a different level of analysis, creativity, and strategic planning. We guide our clients through every phase of the process with clarity, discretion, and precision.

    The services we provide are not built for the masses. They are customized, relationship-driven strategies designed to align with the unique goals, risk tolerance, and personality of each entrepreneur we represent.

    We are not seeking thousands of new clients. We are committed to serving a select group of clients exceptionally well — building long-term partnerships grounded in trust, expertise, and results.

    Principle Commercial Advisors
    Guided by Principle. Driven by Integrity.

    What Our Clients Say

    "John can be trusted he does a really good job I highly recommend him"

    Orville E.

    "Thank you, John, for helping us secure an excellent medical office rental. Despite the challenges, you and your team stayed committed, and we truly appreciate your guidance and persistence in making this possible."

    Munib R.

    "John is a professionals professional. Behind the great sales and customer skills there is a keen knowledge of commercial Real Estate. John helped me navigate a $5M deal with lots of hair on it and he made a critical difference in getting the deal done and over all the hurdles."

    Jan V.

    "John and his team are the best hands down. I've worked with so many brokers over the years, and I can't imagine working with anyone else from now on. They follow up, make sure our company is well taken care of, and make sure that we are getting the best deal. They know that they aren't successful unless we are. I only wish I had known them earlier..."

    Naomi T.

    "John is the best in the business. Our company had some unique needs for a commercial location and having such an experienced professional guide us was exactly what we needed. We will use John for all of our commercial real estate needs moving forward."

    Kevin S.

    "We've known John for a handful of years and when we decided it was time to look for a larger space for our Accounting Practice, he was the first person we thought of. It took a lot of months searching for the perfect spot - it didn't help that we kept switching between leasing a property and buying a property. But throughout the entire process, John remained patient and positive. He encouraged us to really think about all of the spaces we viewed before saying yes. He gave us a safe space to be indecisive and picky and also knew exactly what to say when the process was getting to be too much. We appreciate all of the work John and Tiffany did helping us find our new business home and will definitely reach out to them again when we eventually need something bigger!"

    Salina M.

    "John and his assistant Tiffany were fantastic in helping me acquire the building for my gym. They both were very communicative throughout the whole process and put in the extra effort to make sure I got what I was looking for. This was the "next step" in my business which came with a lot of first time experiences for me. John was great in guiding me throughout the process and helping me understand everything that was outside of my normal scope. I very much appreciate the time and efforts both John and Tiffany put in to me and this project. I would absolutely recommend them (and already have) to my colleagues, or anyone in need."

    Chase C.

    "Working with John has been amazing, Highly recommend for anyone looking to sell/buy their commercial property. I've known john over the past 6 years and he has always been available to chat through anything i've had questions on and has been a great resource. Will work again in the future as the next project comes up!"

    Justin N.

    "John and his assistant Tiffany have been marketing an office space in our building. John uses multiple channels to make sure our listing gets as much exposure as possible-MLS, Emails, and many more marketing tools. We receive a weekly update detailing how many people have viewed our listing, how many are unique viewers and a lot of other information. John and Tiffany have also conduced many tours to show the suite. John and Tiffany are very professional, knowledgeable about the market and very friendly. I would highly recommend John and his Team for any of your Commercial Real estate needs."

    Livia DLR.

    "John and his team are great to work with. They are efficient and always offer friendly advice and check ins."
