Testimonials for Fiona Theseira, REALTOR®

  • catmom32000

    Fiona is ethical, knowledgeable, responsive, funny, patient, and a pleasure to be around. We met her at an open house. Though we were not interested in that house, when we stumble on a house (online) that interested us, we asked her to write the offer. In the end we did not buy that house, nor another house on which we opened escrow. Third time was a charm however. Fiona was a gem throughout our ups and downs. We felt fully supported throughout the process and would recommend her without reservation.

  • joe.pieper

    Fiona was actually referred to me by a close friend. Fiona had worked with my friend with both buying and selling of her properties throughout the years. Fiona was everything that I expected and more. She was patient with me as I searched for the right property that fit my needs. She is extremely professional and ethical. I am very grateful that my friend recommended her to me. I highly recommend Fiona to anyone looking for a realtor. Her professionalism, honesty, and excellent customer service skills has earned her my business for any future real estate transactions I might need. I literally could not have done it without her.

In addition to being a beautiful person inside and out, she can develop and maintain a friendly, positive and professional relationship which is very helpful to first time buyers/sellers like me. THANK YOU FIONA

  • Tanya

    This was my first experience selling a home because I wanted to move closer to work and family. Fiona Theseira made the selling process very quick and simple. My home was listed and sold within approximately 45 days. I would highly recommend using her services to anyone who wishes to buy or sell a home.

  • rampant

    She was a great agent, paid attention to what we were looking for and respected our price range, was never pushy, gave advice when needed, and just a nice and easy person to get along with. A great agent!

  • David & JoJo

    Fiona is very easy to work with and helped us sale my dad's house. We know Fiona because she helped us with my own house 12 years ago. We are very pleased with her skills and support.

  • Amy

    It has been wonderful working with Fiona. She is very knowledgeable and experienced in the real estate market.
    Answered all of our questions, and most important, got a good price selling our house.

  • Linda, San Diego

    Fiona helped me buy a home.
    I had so much fun hunting with her! So easy to contact via email text or phone. So knowledgeable about areas we picked and stayed in them. Can't believe we found our gem and closed in 20 days! Seemed to always be available and willing to look any day

  • Melissa

    I met Fiona through other references and quickly understood that she would be very reliable. While sorting through paper work, details regarding our probate situation, and the history of our home, I felt comfortable discussing options. Fiona is also experienced in dealing with home sales that need to go through probate professionally and personally. If you're not familiar with the probate process it can be bewildering. So finding the right realtor is very important. In the end, we got more than our goal price and the experience was very pleasant. Communication was never an issue, and I felt confident throughout the entire process.
