Success Stories
  • Ann Sullivan is an amazing agent with excellent communication skills and responsiveness AND she has in-depth knowledge of the business. She helped us get our perfect home and ensured it would stay perfect by recommending the appropriate inspectors and experts. We've been in our home for 2 months now and we couldn't be happier. Thank you Ann so much for everything!

    Rebecca and Ceasar
  • Ann Sullivan is an outstanding agent. She is extremely hard working, super knowledgeable of the area and absolutely had our best interests in mind at all times. She was invaluable on walk-throughs and only showed us homes that were on target with our stated desires. We've purchased homes on a couple of prior occasions and I can say, without any hesitation, that Ann is leaps and bounds ahead of the other agents we'd worked with.

  • I am an administrator of an estate trust and I needed an experienced, trustworthy Marin Realtor who knew the San Rafael area well. Ann exceeded all my expectations. She helped us with getting the property cleaned out and staged the home. She worked with the HOA on difficult issues and even got them to change a policy so we could do open houses. The open house was how we got one of our buyers. I was very impressed with the disclosure process and how she advised us and used digital signatures to make it easier for me. When it came to negotiating she was excellent! She marketed the property directly to brokers, potential buyers and even on high-end shopping carts. Ann is an skilled and knowledgeable agent; highly recommended.
