About the Author

Dennis Webb

Dennis A. Webb, ASA, MAI, FRICS, is a business valuer, real property appraiser, former syndicator and engineer. He is an award-winning writer and the principal authority on valuing fractional interests in real estate. Mr. Webb has been speaking and writing for more than 20 years about essential but still-mysterious valuation topics that mix real estate and business. His mission has resulted in more than 70 articles and presentations for valuation professionals, lawyers and property owners, a two-day seminar for valuation professionals, and a predecessor work: Valuing Undivided Interests in Real Property: Partnerships and Cotenancies (Appraisal Institute 2004).

Dennis’ passion is bringing understanding, clarity, collaboration and technology to bear on the valuation of hard-to-value asset interests, a niche specialty that has long proved vexing for appraisers, advisors, the courts, and property owners alike. 

His professional dual-field designation is quite rare.  His emphasis has always been on “engineering” valuation methodology by bringing analysis/data crunching together with persuasive storytelling.


​Dennis is the founder of Primus Valuations®, a multidisciplinary valuation firm with a practice emphasis on real property-related business interests and the enterprise value associated with special-use properties. He has been active in real estate appraisal since 1988 and in business valuation since 1994. He is a member of the Appraisal Institute (MAI), an Accredited Senior Appraiser (ASA) in both real property appraisal and business valuation with the American Society of Appraisers, a Fellow of the Royal Institution of Chartered Surveyors (FRICS), and a lifetime member of the Institute of Electrical and Electronics Engineers.

Before specializing in valuation, Dennis was co-owner of an NASD broker/dealer firm that provided real estate investment syndication, analysis, and consulting services. During that time, he held licenses as a registered representative and general securities principal and was responsible for due diligence investigations. He received a Bachelor of Science degree in engineering from the University of California at Los Angeles with a minor in economics and worked for 15 years as a systems and design engineer. A native of Los Angeles, Dennis now lives in Denver, Colorado, and enjoys writing, hiking, traveling and dancing Argentine Tango (not necessarily in that order).
