Robert really goes above and beyond!

I couldn’t have asked for a better realtor! From day one, Robert was responsive, knowledgeable, and genuinely cared about helping me. He made what can be a stressful process feel easy and manageable. Roberts guidance, honesty, and attention to detail made all the difference. I always felt supported and well-informed. I would absolutely recommend them to anyone looking for a trustworthy and dedicated Realtor.

Expert guidance and exceptional communication from start to finish!

Expert guidance and exceptional communication from start to finish!

I've known Bob for more than 20 years, and in that time I've seen him help our friends buy and sell numerous homes - so when it finally came time for us to buy our first home, there was no doubt who we were going to get to help us! We didn't really know what to expect during the process - but as soon as we talked with Bob, both my husband and I felt at ease. He does a wonderful job at the start of the process walking you through what to expect, and really does a great job with helping you feel as prepared as you can be. Throughout the entire buying process, Bob was incredibly responsive, super communicative, and always on top of every detail - coordinating with other realtors, our loan officer, and everyone else who was involved. He always took the time to explain all the paperwork, and terms that we weren't familiar with, never rushed through our conversations, and always made sure we were comfortable before moving on. His deep knowledge of the market, and all of his recommendations were so helpful! My husband and I always felt confident that we were making the most informed decisions. What really impressed us most is how hard he fought for us every step of the way. Making sure we got the best price, both on the sale of our mom's home, to the purchase of our forever home. His dedication and advocacy went above and beyond what you would expect from a realtor. Having been friends for so long - I should have expected this, since he has always shown an immense amount of dedication to his clients. Bob was the best realtor, and I hope anyone else who is looking to go through this complicated but exciting process, will give him a call. He genuinely cares, he's incredibly knowledgeable, and will go the extra mile for you every step of the way. We cannot recommend him highly enough!

Robert--I called him Bobby-- was recommended by a friend, and I am SO GRATEFUL. At 77, I realized I didn't need and could not properly care for my big 2 story house in Diamond Bar. I had a tentative offer, but Bobby got me much more, a larger move-out allowance, and an earlier closing date. He recommended a fair appraiser, too. Through the sale process he guided me at every turn with the volume of paperwork for the sale, which has doubled in the 30+ years since our original purchase. He was patient, prompt, and good-humored at all times. I am so grateful for Bobby's help with this complicated and important transaction!! He has my strongest recommendation.

First open house weekend generated 6 offers above listed price! Resulted in the sale of my property!

First open house weekend generated 6 offers above listed price! Resulted in the sale of my property!

Yup, he knows his stuff! Who can sell a property on one open house ? Robert Stephen can! He worked tirelessly on my documents, after hours and weekends. Guiding me through a maze of documents and regulations. Very polite, courteous, friendly, keeping me up to date on various statuses of the process. His valuable suggestions on renovations kept me from going overboard and led to a higher sale price. He's no longer my agent, he is my friend.

Sheri was extremely professional and so helpful. It took us 6 months to find a home, Sheri was probably the main reason we didn’t give up. If you are looking to buy a new place do not hesitate, go with Sheri she will take care of you and your family as if you were part of her fam.

Incredible Patience and Wonderful Execution

Incredible Patience and Wonderful Execution

Robert spent weeks preparing our property before it hit the market, making sure everything was just right as we came in a few months behind the early 2024 rush. He remained in constant contact with us during the nearly dozen open houses held. He reached out to other realtors with similar properties, discussed several action plans with us as the property slowly gained more showings, and presented himself professionally to all potential buyers. When we finally had three offers come in at once, he was diligent in his presentation, providing a clear path to the right choice for us. Robert will be our realtor if we ever decide to move back to Southern California.

Best Agent in the San Gabriel Valley

Best Agent in the San Gabriel Valley

My real estate experience with Kathleen was excellent. Her years of experience made her extremely knowledgeable about how to handle this particular sale. She was very thorough and paid great attention to every detail. I can't imagine using a different agent. Everything went smoothly from the initial listing to the close. Whether you are buying or selling real estate in the San Gabriel Valley, she is definitely the best agent to select!
