Client Testimonials

    Marjie was incredibly helpful throughout our entire home selling process. She consistently stayed on top of everything, ensuring that no detail was overlooked. Marjie even went out of her way to check on our house and make sure everything was in order. Her dedication and commitment truly went above and beyond our expectations. We couldn't have asked for a better realtor!

    Marjie went above and beyond with every detail. I wish I could recommend her to every single person selling a house- because she helps with every anxious question I had, she is so responsive, is so detail oriented, and caring. She truly has the best interest of her clients at heart.

    We chose Marjie to sell our Livermore home for many reasons, particularly her knowledge of the market, of Livermore real estate, and the real estate in our community, Arroyo Crossing. Marjie was great to work with and handled every aspect of our home sale with professionalism and expertise. We highly recommend Marjie for sure!

    Marjie represented us when we sold our home in Livermore. We were moving to Texas, and initiated our transaction only a few days before we had to leave town. The entire week before our house was listed, we were on the road, and Marjie handled staging, cleaning, inspections, photos and overall preparation for listing with zero physical involvement from us. We talked on the phone a few times to sync up on what is going on. Everything was done on time and the house was even listed a day earlier than expected! We would recommend Marjie for representing you as a seller in a heartbeat!

    We have had Marjie as our realtor since we bought our first house. She has helped us through the buying and selling process three times now. She is very knowledgeable of the market and our needs as a buyer. We love how responsive she is when we needed help with anything. She took care of the sale of our last two houses and they both went pending after the first weekend. She is extremely flexible and told us what we really needed to hear. We highly recommend Marjie for your realtor needs.

    Marjie was a blessing to us as the selling agent of our home. She lined out the process and was with us every step of the way. What I particularly appreciated was that she knew the market and almost described exactly who/what type of people would be Interested in purchasing our home. She suggested a selling price based on her knowledge of the neighborhood and we got well over the asking price! She has a good knack for staging and though we used experts to inspect, repair, paint and stage - she checked on and followed up on every detail. We couldn’t be happier.

    This is the second time I've worked with Marjie, and I look forward to working with her in the future. She provided quick, accurate, detailed responses to all of my questions and concerns. Her involvement in every step of the process made it very smooth and minimized my stress and involvement. She also provided many small (and large) services not offered by other agents.

    We had the pleasure of working twice with Marjie, once when when we bought our house in Livermore, and again when we sold it nine years later. Both experiences were very positive for us: she took the time to explain things as needed, and made it such that there were no negative surprises. Over the course of that intervening time, she also connected us with helpful professionals for refinancing, etc. Marjie works very hard, communicates very well, and provided us with many extra services at her cost that really made us feel like VIP clients.

    We have worked with Marjie on two occasions after a friend recommended her to us. She knows in detail the Livermore market. To me she acts more like a partner than just your agent. I have been impressed the way she helped us first when buying and then second when we were sellers.

    Marjie represented me as the seller while also representing the buyers of my house. Normally I would not seek this arrangement, but Marjie had brought the buyers to me, and me to them. Marjie was expert at navigating the line between buyers agent and sellers agent, and is great at thinking outside the box. I would highly recommend her to represent me in the future or anyone else I know who is looking to buy or sell. Big thumbs up!

    Marjie became a friend of my wife and I during frequent visits in the prior 5 years. Her reputation for other listings in our neighborhood was excellent. She coordinated all aspects of our listing and sale in a timely and professional manner. Her firm provided a reduced 4.95% commission. Marjie recommended an increase in asking price just prior to open house and the offers even exceeded that. Immediately after only one open house, we had a cash deal with no contingencies (zero fix-up expense) and a fast closing. This was truly a painless transaction.

    Margie handled the sale of our last home. We found her to be very professional and helpful. She knew the market we were working in and advised us very well. We would use her again and would not hesitate to recommend her to anyone looking for a competent and caring realtor.
