Relationship-driven real estate — rooted in
San Diego, backed by generations of trust.
Real estate isn't just my profession — it's in my family's DNA. As a third-generation San Diegan and third-generation Realtor®, I grew up watching my family build lasting connections through this work, and I've carried that legacy forward with deep pride.

I will be with you every step of the way.
As an Associate Broker backed by ENG Properties, I pair lifelong local knowledge with the resources of a respected brokerage. When I'm not helping clients find or sell homes, you can catch me filming real estate segments for KUSI, cheering on my four kids at their sports, or soaking up everything this beautiful city has to offer.

"I cannot say enough wonderful things about working with Katy Sullivan! I have known Katy since high school, and when it came time to make the biggest purchase and investment of my life, she was the first and only person I called. Her knowledge, professionalism, and genuine care for her clients are unmatched."
"Katy was a pro through and through. Thorough, great communicator, listened and understood what we were looking for, proactive and not afraid to do outreach or ask questions on our behalf. She made a potentially stressful process seamless and enjoyable."
"Katy is absolutely amazing! We were first-time home buyers and she walked us through every step of the way. She answered every nuanced question and would help us negotiate and think strategically. We wouldn't have our dream home without her!"
