Customer Testimonial

Shari Lorenz

Seller Rating:

Shari Lorenz is an excellent choice for a real estate agent. She not only is very knowledgeable about every aspect of her job, she is professional and very accommodating. She has this amazing ability of making me feel at ease even when I was feeling anxious or unsettled with any decision during the process of the sale. If there was a question that she didn't know the answer to in the moment, she made every effort to find the answer as timely as possible. Even though my sale went very quick and extra smooth, I still needed her expertise and experience to support me and she was on point at every turn. Being a single Mom and small business owner, I am so am so very grateful that Shari was there to support me with the biggest decision I've made in my life to this day! Thanks Shari for all you do! - Laura Ramirez August 2017

We've dealt with Amy for two home purchases and the sale of our first home. I wouldn't even consider using another agent.

We used George and Anna Steffensen in a previous transaction. Both times we've worked with them they were very professional and used their skill and knowledge of the market to make the selling/buying process run smoothly. Usually buying and selling a home from a clients stand point can be very stressful but with the help of great agents like George and Anna it was very easy and stress free. I would definitely recommend George and Anna to any one of my friends or family and will definitely use them again in the future. Thank you for helping us buy our dream home. - Arturo Hernandez, Rohner July 2017

I went through a horrific divorce that forced me and my children to move out of the house because he refused to leave. Julie helped me list my house as well as hold my hand during the entire process. The escrow process took much longer than expected due to the buyers lender, but Julie followed up daily and kept me informed of any and all updates. I couldn't have gone through this whole process without her. I would highly recommend her as an agent to anyone buying or selling. You will be in good hands! - Kate Stefan, Santa Rosa June 2017

I cannot think of a better buying experience. Jeffrey did an amazing job at understanding all of my needs, caring enough to Lear the "need behind the need" and then find me properties that was exactly what I was looking for. Every home we visited felt like a perfect fit. Although I only purchased one I could definitely see myself living in each home visited. I will definitely be recommending Jeffery to all of my friends and family. - Robert Erdmann Rohnert P June 2017

As a first time home buyer, I could not be happier with my new home and with my selection in Miriam Pengel from Century 21! Miriam explained every step of the process and was always there to answer all of my questions and concerns, no matter the day of week or time of day. With her knowledge and expertise, she turned the stress of home buying into a very positive experience. I cannot imagine having gone through this with anyone other than Miriam. I highly recommend her to anyone who is interested in buying or selling their home. She is not only my forever realtor now, but she is my friend. Thank you for going above and beyond for me during this process Miriam. Century 21 is lucky to have such a friendly, knowledgeable and hard-working Realtor on their team and I can't wait to purchase my next home with Miriam's help again!

Thomas Jones

Seller Rating:

I found Tom Jones when I was doing research to find a broker to sell my mothers home. Out of the three that I interviewed, Tom was the only who made me feel like selling my mothers home was his only priority. Tom was on top of everything and kept me informed of what we needed to do to get the house ready and once it was, he kept me informed on the status & process of selling the home. Words cannot express how much of a joy it was to work with him.

He was a joy to work with.

Although I rarely dealt with any of the staff, when I did, they were very warm and welcoming.

Everything from start to finish ran perfectly thanks to Tom. - Debra Guyer, Cotati Ca December 2016

Janis Ralph

Seller Rating:

Janis Ralph was the most impressive when she came to see my place and speak to me,she made me feel safe, I felt she understood what my needs were and she felt my property was worth more than anyone else mentioned and she came through with that because I sold my property for more than anyone else thought I would and it's because of her I couldn't have done it without her, she held my hand through the whole process she was terrific.

I had two offers that looked fabulous and they both back out I was discouraged and Janice was not,she had me take the house off the market for two weeks to give it a fresh start and as soon as we put it back on the market we had an offer and it was a great full price no contingencies It was a beautiful thing and I owe it all to her.

She was more than excellent she became a friend,she help me through this emotionally and physically I can't say enough good things about Janis, I would highly recommend her to anyone selling or buying a home. - Marie Seger Rohnert Park December 2016
