More about Diana Williamson

Business Philosophy

Customer service oriented – attention to detail – a stellar reputation for meeting deadlines in a timely and efficient manner – are only exceeded by Diana’s ability and commitment to delivering uncompromising results to her clientele.

“Diana always displayed a high degree of integrity, responsibility and ambition.  I’ve worked with her in several different settings from the most conservative with strict guidelines to a start-up environment that required everything to be established from ground zero.  In both cases, Diana was able to quickly prove there was no task too small or issue too large for her to handle and resolve efficiently and effectively.”  Corrie Zaldivar (Director of Finance, The Irvine Company).

Experience & Education

Diana, who received her B.A. in Business Administration from Cal State Fullerton, has held consulting and management positions for leading Orange County firms such as The Irvine Company, First American Title, Coldwell Banker Relocation, Grubb & Ellis, American Healthcare Investors, and Ameriquest Mortgage, where in addition to working as part of the management team, she worked closely with the property management and leasing departments. 

Her ability to learn quickly and adapt easily to different situations and challenges has proven to be paramount to Diana’s success.  She enjoys working with people from all walks of life, with a strong commitment to ensuring that each of her client’s goals and expectations are highly satisfied.


As an Orange County native, Diana has lived, worked, played and raised her children in Irvine for the past 30 years.   Diana and her family have long been actively engaged in every aspect of life in the community.  She has a wealth of first-hand knowledge of the area, from schools and neighborhoods to the most current trends in the housing market, all of which serves her clients well.  Diana currently sits as a Board member with Woodside Homeowner's Association (Irvine).

Backed by the tremendous resources and support available through Coldwell Banker, Diana looks forward to assisting you with all of your real estate needs.
