About Us


In 2004, Big Valley Properties opened its doors in Hayfork, CA with Broker/Owner, Retta Treanor and her philosophy….
“If you take care of your customers and always put them first, success will follow.”

That is the foundation on which Big Valley Properties was built and continues to do business today. Quickly skyrocketing to the Top Selling Brokerage position after only 2 years in business, Retta Treanor was determined to make a difference with the Big Valley name and that she did.

Opening our Weaverville office in 2006, managed by Top Selling Agent, Shannon Aikins for 18 years and counting; a team of Agents dedicated to a customer driven focus; empowered by a strict code of ethics, we as Realtors® take an oath to adhere to; and the pride we take in our fiduciary duties in which we are bound to; is why today, BIG VALLEY PROPERTIES proudly celebrates over 3,000 clients served and our 20th year anniversary supporting the communities we love through the buying and selling process.
“It has been an extreme honor to be a part of the community I was born and raised, in this capacity. Big Valley Properties is celebrating 20 years because of our clients that have trusted us over the years with such a major life decision; buying or selling a home; and they continue to do so today. We are forever grateful and look forward to many more years of supporting the communities we love, Trinity County.”

-Retta Treanor, Broker/Owner


The Big Valley Family is dedicated to supporting the communities we call home. With trade school scholarship programs to support our youth's education, event sponsorships and monetary contributions throughout Trinity County every year; community is and always will be a top priority of ours.
