Diana Harton

We loved working with Diana to buy our house in North County San Diego. She was professional and knowledgeable and kept us calm during seriously stressful negotiations. She was always available for showings, extremely responsive, and willing to talk late into the night. We got our home at fair market value thanks to her advocacy. I recommend her wholeheartedly.

A sincere thank-you to Diana and The Oppenheim Group! Our unique, sophisticated home required special attention, and Diana delivered. She handled every open house with professionalism and expertise, elevated our marketing, and addressed issues quickly so we never lost confidence. We sold much sooner than expected. Highly recommend Diana and the team.

This is a note of thanks for Diana’s work on the sale of our home. Our move was complicated—we relocated both home and business out of state. Diana’s grasp of market conditions and buyer analysis let us focus on everything else. She was direct about what to do for maximum price while being empathetic to our time and budget. She sold our home in a few days and didn’t waste our time on anything unnecessary. She exceeded expectations on every level. If you value your time, energy, and sale price, hire Diana.

We spent over three years searching for a home and faced constant discouragement—until we met Diana. Within our first week together, she toured multiple houses with us and got us into escrow. A sudden layoff forced us to back out, and she handled it with empathy and professionalism, taking care of everything. Over a year later, she was just as excited to help us try again—and we closed on our new home. She fought for us and believed in us every step. Honest, trustworthy, faith-filled, and professional—Diana is the real deal.

If you want a realtor who truly cares, I can’t recommend Diana enough. Through the highs and lows, she was there with answers, reassurance, and genuine joy for our wins. She opened doors I don’t think other realtors could have. Always available, incredibly knowledgeable, and a true people person—she changed my mind about how essential a great realtor is.

Diana is nothing short of extraordinary. From the start, she brought unmatched energy, passion, and expertise that made buying a home smooth and even exciting. We were relocating to Carlsbad, and her intimate knowledge of Carlsbad and Encinitas was invaluable. She didn’t just show us homes—she introduced us to neighborhoods that aligned with our lifestyle and long-term goals. Her attention to detail, creative problem-solving, and constant communication kept everything on track. Beyond her professionalism, she truly cared about our family. Thanks to Diana, we’re now in our dream home.

I had the pleasure of working with Diana on a shared transaction, and she was excellent from A–Z! Her professionalism is top-tier. Her knowledge and expertise made the transaction feel effortless. She’s genuine, cares deeply, and is someone I know I can count on. I’m excited to do more deals together!

I was completely satisfied selling my home for the first time using Diana as my listing agent. All the metrics exceeded my expectations: 8 days on market, 21-day escrow, and a list-to-price ratio of 1.15. She recommended the perfect listing price—high enough to attract strong offers without overwhelming us—so we had just the right number to choose from.

Diana is fantastic! She helped my wife and me sell and purchase a new home. Diana and her team worked tirelessly to hold open houses, network with realtors, and answer endless questions. We chose her based on the numerous sales she completed on our street alone! Multiple times we said, “I’m so glad she’s our realtor.” We’re ever grateful—thank you, Diana!

In the 40+ years I’ve been associated with real estate, I have not observed anyone who has done a better job with sales and marketing than Diana Harton. She maintains professionalism while showing genuine compassion for her clients’ needs. Her understanding and willingness to work around special circumstances sold us on Diana from the start. We would recommend her to represent any price point of residential property in Southern California.
