    "As first time home buyers, the prospect of buying a house was quite daunting. Being able to rely on somebody as helpful, engaged and knowledgeable as Marguerita was invaluable and made the process so much smoother. At each step, she went above and beyond to ensure we had everything we needed to be able to make good decisions, without ever being pushy. She is an amazing person and a true asset to have on your side: somebody you can trust so thoroughly that she will put your best interests first."

Chris & Samantha Adams

"We had such a blast working with Marguerita! She was tenacious, looking at every detail and never tiring during our very long "short-sale" process. We knew we were in the driver's seat and she was there to support us. She treated us as if we were her most important clients. We respect Marguerita for her work ethic and all around good attitude. Thanks a million Marguerita!"

Dan and Carrie Pierce

"I was honored to have Marguerita as my agent and loyal friend. She represented me very well in my recent land sale with professional tenacity and her upbeat, reassuring personality. She was consistently thorough, fair and ethical as she worked with many possible buyers and their agents. She was an absolute pleasure to work with throughout the whole process. I will recommend her always without reservation."

Steve Moll

"It has been my pleasure to have worked with Marguerita for the past 5 months in purchasing a home. Her continual communication with me on new listings and properties available was more than I expected. My experience with past realtors was nothing like this. Her positive approach and never ending energy gave me confidence daily that we would find the right place to settle into. Importantly, she listens to what you have concerns about, and doesn't try to sell you on something else. I am forever thankful for the times we spent together, and her kindness in pursuing the right home for me. She's a gem!"

Linda Scinto

Marguerita is very conscientious and thorough. We always felt that the "t's" were crossed and the "i's" were dotted. She answered our questions intelligently and gave us good advice making the process of buying our home go very smoothly. Marguerita lives with her family in Sonoma so she knows the area well. We felt comfortable and confident with her referrals too."

Pattie & Bill O'Connor

"Marguerita is a gem! She stuck with us through three years of searching, multiple offers and many weekends and evenings. We thought we would lose her when we changed our search from Sonoma to Petaluma, but she stayed with us, researching properties and driving over to Petaluma to view homes with us. She always maintained a positive outlook, confident she could find us the perfect home. Marguerita's opinions were insightful and helpful, and I always felt she was looking out for us. We couldn't have found a better partner for our home search!"

Bonne & Peter Posert

"A year ago I embarked on a journey to find the perfect house on a very small budget. Along the way, I worked with several real estate agents because I was researching alot of different territories so I would use local agents for each area. I was so disappointed in the incompetancy of almost all of the agents I worked with. Most would not return calls, missed important emails and wasted alot of my time showing me properties that did not fit my criteria. I was ready to give up when I walked into Marguerita's office one day at CENTURY 21 Wine Country in Sonoma, CA. She welcomed me immediately and brought me back into her office and helped me research properties in the area.  She listened to me and took seriously what I was looking for in a house. She did not try to talk me into looking at properties that did not fit my criteria. Marguerita made herself completely available to me from that day on until we found the perfect house. She was supportive every step of the way and I could not have done it without her. She restored my faith in real esate agents! Having the right agent makes all the difference and I highly recommend Marguerita to anyone who is willing to wait and get exactly what they want."

Rachael Adams

"We feel so lucky to have found Marguerita for our realtor. Our past experience left us very discouraged, but Marguerita brought a positive spark that we needed to proceed. She was quick to show us properties that she felt we would be interested in. When we finally had an accepted offer, she was professional and persistant when it came to working with the sellers and the banks. Marguerita helped us find the perfect house. It was a pleasure to work with her."


Mike and Mary Studer

"Marguerita was referred to us by a friend who had worked with her to purchase a new house and sell an old one. We were so happy that she did as we loved working with Marguerita on the purchase of our new home. She was continuouslycommunicating with us and explained every part of the process as we were going through it. When our closing was full of difficulties due to our bank, she was right there helping to push them to get it closed and get us into our house. Thank you so much Marguerita, you are the best!"

Lisa and Ross Dencklau

"When I decided to purchase a condo in Sonoma, it was with a sense of excitment, but also some anxiety about how the process would proceed. As it turned out, it couldn't have been easier. A realtor friend of mine evaluated the performances of various realtors in Sonoma, and she recommended I talk with Marguerita. From our first meeting it was clear that she was there to find the condo that I wanted, and to make the process as anxiety-free as possible. From keeping me informed of all the options available, responding immediately to any questions or issues, being available at a moment's notice to look at properties, coordinating the entire process, and just basically being a supportive and encouraging advocate, I couldn't have asked for a better person on my side. I now live in a beautiful condo in Sonoma, and am blessed to count Marguerita as a new friend."

Kathleen Randles

Marguerita - I wanted to take time out to say Thank you! You made buying a home in today's market super easy! I appreciated your thoughtfulness, attention to detail and you were always quick to respond to all of my questions. Along the journey, you never changed course and I feel extremely grateful to have found you. Thank you again for your services, expertise and professionalism.

Gia Scinto

Our family had the pleasure of working with Marguerita as both buyers and a sellers. When we first met, we were thinking of moving to a larger home and within 4 months, we were in a fantastic new home and had sold our old home. All of this went very quickly and smoothly. Because we both work and have 2 small children, we assumed buying and selling simultaneously would be nearly impossible. Marguerita made the impossible possible. Already we have recommended her to our other friends and will continue to do so!

Brett & Sarah Pinkin

"Marguerita did a great job with representing us on a purchase of an investment home and on the sale of an investment home in 2012. We had a great working relationship and she always had our best interest in mind! We look forward to working with her more in 2013!"

"We were very pleased with Marguerita. She found just what we wanted at the price we could afford. She stayed on top of everything till the escrow closed. I would use Marguerita again and highly recommend her to anyone looking to buy or sell."
