Testimonials
★★★★★
"Frank is a very knowledgeable, communicative and personable broker that successfully helped us sell our home in Bernal Heights in only 10 days for 15% over asking price. His marketing approach is excellent, he created a personalized website with beautiful pictures of our property and held open houses not only for potential buyers but also for brokers and neighbors. He held our hand throughout the process and took care of every single detail for us as we didn't live in the same state anymore during the selling process. We would wholeheartedly recommend him to any seller!" - Seller

"Over the past 5+ years, I watched Frank sell the houses on either side of us in Bernal Heights. Both neighbors had nothing but great things to say and they both fetched top dollar for their homes. After 27 years in our house it only made sense to call Frank in when it was time to sell ours. It was the right call! We essentially handed him the key and he did everything, start to finish. Frank got the job done quickly, completely without issues and we got the price we were hoping for. He was clear, organized, positive and responsive. Thank you, Frank!" - Seller

"Frank was amazing! It seems like all San Francisco realtors know Frank well, and that really helped when the time came for us to make offers. Not only Frank's personal relationships with sellers agents helped ease the process, his deep knowledge of the market was crucial in getting us our new home. I highly recommend Frank, and would love to work with him again!"

"Franks extensive experience puts you immediately at ease, and guides you through a very effective decision process, highlighting key value decision points, colors, photos, inspections and ultimately a personalize website just for your unit. We were blown away by Frank and his team's attention to detail and for effectively bringing forward the sale of our top floor condo unit in Russian Hill. I'll recommend Frank to anyone that is serious about selecting an experienced agent with the needed competence and attention to detail to realize the value of your real estate investment. Thank you Frank & Team!" - Buyer
