About Diane Reilly

Diane Reilly has been a dedicated Realtor® since 1996, consistently ranking among the top producers in Alameda and Contra Costa Counties. Her commitment to exceptional service has fostered enduring relationships with a loyal clientele. Diane's approach is characterized by her genuine nature, strong communication abilities, and tailored service.

With a diverse professional background that includes roles as a legal secretary in Australia, an executive secretary in the aerospace sector, and a human resources specialist for a global oil well drilling company, Diane brings a wealth of experience to her real estate practice. She understands the critical importance of precision, attention to detail, and innovative negotiation strategies in today’s dynamic real estate landscape. Her previous career as a flight attendant for a major airline further enriched her interpersonal skills, allowing her to provide clients with a first-class experience.

Diane's passion for real estate began long before she entered the field. Inspired by a mentor, she built her own investment property portfolio, which informs her work with clients. She finds equal joy in guiding first-time homebuyers through their initial purchase as she does in assisting seasoned buyers, sellers, and investors. Her patience and expertise ensure that every transaction is seamless and successful.

Diane holds several prestigious designations, including Certified Residential Specialist (CRS), a title held by fewer than 6% of agents nationwide, as well as Global Relocation Specialist and Senior Residential Specialist (SRES). She particularly enjoys helping clients transition to active 55+ communities, such as Rossmoor in Walnut Creek.

Originally from New Jersey and raised in Southern California, Diane has called Northern California home since 1974. She is a proud mother of three and cherishes her role as "Grandma Di Di" to seven grandchildren. Outside of her professional commitments, Diane actively supports community organizations and enjoys fitness, golf, travel, and dancing.

Diane is a member of several professional organizations, including the National Association of Realtors (NAR), California Association of Realtors (CAR), and Contra Costa Association of Realtors (CCAR).
