About Kathleen Seibel
Kathleen is a distinguished REALTOR® with four decades of experience, consistently ranking among the top 1% of agents in Petaluma. Her expertise extends throughout Sonoma County, as well as Marin County and the Vacaville area. Over the years, Kathleen's passion for real estate has only intensified, and she finds great fulfillment in her work. Her clients, many of whom return for her guidance across generations, appreciate her steady and reliable support. Known for her approachable demeanor, Kathleen excels in assisting first-time homebuyers, selecting properties she would confidently recommend to her own family. Her dedication to facilitating smooth, low-pressure transactions has fostered strong client loyalty.
Kathleen's affinity for real estate is deeply rooted in her family background. Raised in San Francisco, she was influenced by her father, who served as President of Northern Counties Title Corporation, along with several relatives who also worked in the industry. Before transitioning to real estate, Kathleen spent seven years in inside sales at IBM, ultimately seeking the flexibility and opportunities that a career in real estate could offer. Additionally, her ownership of AA Notary & Signing Service allows her to provide comprehensive support to her clients during and after the closing process.
In 1982, shortly after obtaining her real estate license, Kathleen relocated to Petaluma, a community she cherishes for its affordability and family-friendly environment. While her three sons were in school, she actively participated in local organizations, including the Petaluma Valley Little League and the Casa Grande High School Booster Club, as well as initiatives within the Petaluma and Old Adobe School Districts. Now married for over forty years to Joe, a teamster, Kathleen dedicates her time to the Petaluma Elks Lodge and enjoys spending time with her two young grandchildren. The family also cherishes their annual trips to Scottsdale, Arizona, for spring training.
**Client Testimonials**
"I've worked with many REALTORS®, and it’s the ability to swiftly resolve issues that distinguishes a good agent from an exceptional one. Kathleen Seibel truly exceeded my expectations. When I needed information from a closed bank, she demonstrated remarkable creativity and resourcefulness, quickly locating a vendor's contact and expediting the resolution of what could have been a lengthy problem. Her responsiveness and determination to solve issues immediately left me impressed. All I can say is WOW and thank you!"
