    Tony, Elana, and the TAG Real Estate Team sold our home, and we only wish we had hired them from the beginning! From the moment we made the switch, we knew we were in good hands. A marketing machine for our property. From the very start, they proved to be trustworthy and strategic, providing a detailed pricing analysis and a comprehensive review of comparable properties. Their deep connections across the entire SF Bay Area were invaluable. The team is caring, committed, and always working tirelessly for their clients. They consistently went the extra mile. Thoughtful, available, and truly dedicated—thank you, Tony, Elana, and the entire TAG Team!

    Carrie & John – Sold Their Home in Livermore

    Tony and his team were wonderful to work with. We sold and bought a new home with him. His team is very professional, knowledgeable, and trustworthy. They also have lots of connections with other realtors and lenders, which helped us get a house off-market! Highly recommend working with Tony and his team.

    Taylor – Bought a home in Auberry

    My husband and I came to Tony with quite a laundry list of must-haves for our first home; move-in ready, lots of space, tight budget and to be moved in before my vastly approaching due date. Yeah, we were THAT first time home buying couple. He took on the daunting task head-on and worked tirelessly to find us just the right house. He was very communicative throughout the entire searching and purchasing processes and was able to get us into a beautiful home quicker than expected. We couldn't be happier with the house and location and highly recommend The Arsondi Group for their real estate expertise!

    Clifford family- Bought a Home in Mountain House, CA

    I would highly recommend Tony Arsondi (Arsondi Group/Keller Williams) to anybody looking for a realtor! From the moment I contacted Tony with interest in buying a home, he went to work immediately to help my wife and I find the home we wanted. Luckily for us and because of the work Tony assisted us with we were able to close on the home we wanted within one month of starting our search! Tony is very professional and informative on the entire process which allowed us to get the house we wanted. He has spent a lot of time with us on the phone answering our questions, meeting us at the property and communicating with the other realtors/sellers involved to make sure we were informed and comfortable with our decision. Tony made it clear from the beginning that he wanted to make sure that we got the house WE wanted and made sure we didn’t feel any pressure of buying a home we didn’t feel comfortable with. Now we have a gorgeous home that we will be starting our family in! I would refer him to any of my friends and family! THANK YOU TONY!!

    Dan & Michelle – Bought a Home in Brentwood, CA

    Tony made miracles happen for me! I owned a home that was distressed and the sale was complicated, to say the least. Because of his expertise and perseverance I was able to walk away free and clear which was an absolute amazing feat. He’s the best! I wouldn’t hesitate to refer him to anyone in need. Believe me, no one thought it could possibly work out the way it did! I am so grateful for their service and friendship!! Thanks, guys!

    Karen – Sold a Home in Livermore

    "Tony, his team and his partner/wife were exceptional in the marketing, and selling of my investment property. Before selling my property I followed the trends in my community and witnessed first hand his selling techniques through closing. Usually his listings were on the market one week and sold over asking price. When I become serious of listing my property I asked my staging friend whom she recommended. She recommended Tony and his team. She didn’t hesitate. Tony and his wife are knowledgeable with the fluctuations in the market, gave sound advice, are great negotiators and dealt with all issues thrown at them seamlessly. I had a great experience. One thing I wished I had done was met them earlier."

    Henrietta – Sold a Home in Livermore

    "Tony and his team were excellent. He was patient with all of our crazy questions, (we were first time home buyers, so we had lots of questions) he ensured we knew exactly the terms and deadlines that we were expected to meet, all while coaching us along the way. The team is detailed oriented and ensured nothing was missed. He was in constant communication with us during the entire process even on his vacation days and late in the evening. I was amazed by the dedication to ensure our initial deposit was safe, he took every precaution to ensure it was kept safe. We even encountered an communication issue with our lender and title company, and Tony was quick to follow up with them and ensure the issue was dealt with in a timely manner. As he called it he was our "quarterback" which is a perfect description of it.. Thank you for all the hard work and helping us learn along the way. we love our new home"

    Jessica – Bought a Home in Pleasant Hill

    "Tony had great recommendations when I was looking for a Real Estate Agent. When I chose Tony, I felt relieved, happy and excited because he was on time for our first appointment. His knowledge and expertise was amazing. He was not pushy in his assessment and presentation on his views of selling homes. He has a way of putting the client first and relaxing them at the same time.. I would highly recommend Tony to anyone looking for a realtor."
