Lisa Parker - Broker/Owner
Realtor & Mortgage Loan Specialist
Licensed in AZ and CA
CA DRE Lic #01769058
AZ DRE Lic #BR717500000
NMLS Lic #302878
Lisa is the Broker/Owner of Integrity Real Estate & Mortgage Services and a licensed Real Estate Broker and Mortgage Loan Originator in both California and Arizona. With more than 40 years of experience in the real estate and mortgage industries, she brings an exceptional depth of knowledge, experience, and problem-solving ability to every transaction.
Lisa represents buyers, sellers, and investors, combining strong negotiation skills, attention to detail, and a tenacious commitment to protecting her clients’ interests. She understands that successfully buying or selling a home involves much more than simply writing an offer or putting a property on the market. From pricing and negotiating to navigating inspections, appraisals, and the inevitable challenges that can arise along the way, Lisa stays personally involved from beginning to end.
On the mortgage side, Lisa is affectionately known as “The Loan Whisperer” for her ability to find solutions for even the toughest loan scenarios. She prides herself on looking beyond the obvious when a client’s situation requires a little creativity and persistence.
Having extensive experience in both real estate and mortgage lending gives Lisa a unique perspective on the entire transaction.
Born and raised in Southern California and coming from a family of real estate professionals and educators, Lisa has deep roots in the communities she serves. As the proud mom of a United States Marine, she has a special appreciation for those who serve our communities and our country. That appreciation inspired Integrity’s Educator, Military & First Responder Appreciation Program.
Whether you’re buying or selling a home, investing in real estate, refinancing, or trying to solve a financing challenge that someone else has told you can’t be done, Lisa brings the experience, tenacity, and personal attention to help you get from “What if?” to “Closed!”

Celestina Uriarte
Mortgage Loan Originator
Licensed in CA
NMLS Lic #1420042
With more than 20 years of experience in the California real estate and mortgage industries, Celestina brings a wealth of knowledge, creativity, and determination to every client she serves. She understands that no two clients—and no two loan scenarios—are exactly alike. Rather than taking a one-size-fits-all approach, Celestina is known for thinking outside the box and exploring every available option to help her clients find the RIGHT loan program with competitive rates and terms that fit their individual needs.
Attention to detail and ethical integrity are at the heart of the way Celestina does business. She believes her clients deserve more than simply getting a transaction closed—they deserve someone who genuinely cares about their goals and looks out for their best interests. That commitment perfectly reflects Integrity Real Estate & Mortgage Services' philosophy: “We Treat You Like Family.”
A longtime Oceanside resident, Celestina has raised her family in the community and has firsthand knowledge of the Southern California market. Her experience extends throughout San Diego, Riverside, and Orange Counties, giving her valuable insight into the diverse communities and real estate markets she serves.
Whether working with a first-time homebuyer, a repeat buyer, a homeowner looking to refinance, a buyer considering an REO property, or a client navigating a more complicated mortgage transaction, Celestina brings the same combination of experience, persistence, creativity, and personal service to every transaction. Her goal is simple: find the solution that works for her client and make the journey to the closing table as smooth as possible.
