Our Team

TJ Nelson

In 1965, after ten years internship in various agricultural pursuits which includes a partnership with his best pal Dr. H.J. Kristal, in the formation of Kristal and K & N Farms, TJ liquidated his ranching interests, bought a Stetson, a pair of Tony Lama boots and formed TJ Nelson & Associates Inc., Ranch and Land Brokers. In the ensuing 40 years, TJ built a client list, network, sales history and deep knowledge of the area that truly stands alone.

Since the beginning, TJ’s focus was serving the agricultural community by selling rural properties, rural sub-divisions and production properties such as forest lands, orchards, cattle ranches and recreational lands. In recent years, TJ has expanded the companies focus to include vineyard site selections, industrial tree farms and large estate parcels.

TJ has grown this company by example, guided by a philosophy that his staff should always deliver tangible value through better knowledge. Conversion of once large productive ranches to recreational parcels, creation of legal parcel via certificates of compliance and preservation of lands by conservation easements, are just some examples of the methods to delivering tangible value that TJ understands and has taught all that work under his leadership.

David Katz

Over the past three decades David has been extensively involved in natural resource management as an entrepreneur, consultant, and real estate professional with wide experience in the non-profit and business sectors.

David has had extensive experience in managing complex real estate transactions. He is well versed in regulatory and management issues related to food production and processing, timberland management, wetlands, and conservation easements. He is thoroughly familiar with current land use regulations applying to subdivision, site and road development, water rights, and agricultural development.

As one of the first organic farmers in California, David played a pivotal role in the creation of the organic food movement. He was one of the first sustainable farming visionaries to introduce certified organic products to the California market in the early 1970s. He co-founded California Certified Organic Farmers, the first organic farming organization in the country to establish a formal certification process, and was a founding board member of the Organic Farming Research Foundation in 1992. In this role, he was actively involved in developing a grant-making program that eventually catalyzed many millions of dollars of public and private funding for organic agricultural research.

Earlier in his career he was a co-founder and the first Executive Director of the Farallones Institute; he served as Executive Director of the Sonoma Land Trust, and has served as California Director of Trout Unlimited. Earlier in his career he served as the CEO of Ag Access Corporation, a leading provider of agricultural information services.

Ronald E. Lipori

Most probably the guy who knows more about production land than any of his industry contemporaries. Ron is a tireless and tenacious negotiator with patience and persistence. As a matter of routine, Ron can manage seemingly impossible transactions through escrow. He has been the “go to” professional within our office, for matters related to the building industry, for over 21 years.

Glenda Sales

Also a licensed real estate sales agent, Glenda has managed the office since 1999. More importantly she coordinates and develops all of the information available relative to our property listings including the producing of maps, aerial photos, soils and zoning information and extensive brochures. Glenda has relationships with virtually all oversight agencies, accessing the best information and arranging for qualified experts to accomplish tasks required to evaluate and eliminate risks, establish valuation and determine the spectrum of land use potential. Regardless of task, we all know that when Glenda says, “it’s done” – it’s done and it’s right.

Glenda is a member of the Rotary Club of Windsor, where she was recently named “Rotarian of the Year”. She is currently in charge of the Rotary’s International Youth Exchange Program, and was past President of the Windsor Chamber of Commerce.
