Seller of 250 Middleton Dr, Boulder Creek
As first-time home buyers in the US, we couldn’t have asked for a better realtor. From day one, he was incredibly emphatic, patient, knowledgeable, and supportive, taking the time to walk us through every single step of the process and making sure we truly understood what to expect. No question was ever too small, and we always felt comfortable reaching out. His customer service and follow-up was exceptional—he kept us informed, checked in regularly, and made sure nothing fell through the cracks. His knowledge of the market and his extensive network of suppliers are impressive and made the entire journey seamless. Most importantly, his honesty and guidance gave us confidence in every decision we made. He truly had our best interests at heart, always acting ethically toward all parties involved. We are so grateful for his continued support and highly recommend him to anyone looking for a reliable, professional, knowledgeable, and dedicated realtor, especially those getting their first property.

From start to finish in both selling our old house, and buying our new home, Mario and his team were helpful, knowledgeable, and accessible the whole way through. He made the process easy, and helped reduce so much of the stress that can be involved in the home buying process.
Seller of 12670 East Street, Boulder Creek
I was referred to Mario by friends. Initially, I didn't think he would be interested in my situation, but after our first meeting, I knew he was the right agent for my unique circumstances. He had a genuine, positive, and determined approach, along with committed action. He assisted with lenders, lawyers, and service calls, and was always available. He used effective marketing and networking to connect us with the right buyer for my unique situation. I am impressed with his team, his knowledge, and his enthusiasm. "To succeed in business it is necessary to make others see things as you see them." - John H. Patterson Mario understood my goal; he saw more and therefore exceeded my expectations. With much respect and appreciation, Cassie

Met Don over 21 years ago when got matched up with him in buying a condo. We have stayed in touch through out the years. He is a dedicated professional and extremely knowledgeable as a realtor. When I randomly found a new place, Don was my first call! While the process is hectic, Don is always there thru every step. When a few projects are done, Don will be my listing agent to sell the condo.

Seller of Apartment C/14656 Big Basin Way, Boulder Creek
Karen is the best realtor I ever work with, professional, knowledgeable, precise, accommodating, and truly supportive of my specific needs and requirements. She understood clearly what my goal in selling and made it all the arrangements even before I asked about it. She is very passionate about her work and it shows, in the south bay Italian community she is our top realtor choice for all the families that are looking to buy or sell.
Buyer of 19013 Clemans Drive, Castro Valley
Karen was more than a real estate agent, she's a real estate fairy godmother. She helped us find our dream home, albeit a fixer upper, but she saw the house's potential before we did. She and her team's market knowledge and strategic guidance helped us purchase our dream home in our dream location, AND renovate it IN OUR TIMELINE. Who knows of a successful renovation that stayed within the projected timeline?! She communicated with her contractors frequently (there were many), and ensured that our expectations were met. If there was any concern, she hopped on the phone to solve it quickly. She truly went above and beyond for us as if we were family. I will literally refer her to anyone thats even remotely interested in buying a home :)
Seller of 41366 Charlita Ct, Fremont
Karen is such a professional realtor that she used her profound expertises to help find our dream house within a short period of time. She also shared with us all her insights on how to kick start our renovation project. Her connections with Finance/GC/Architect etc. made the whole process so smooth.
