2,990 real estate agents in Contra Costa County

Last May 2025, when my husband and I first contacted Mareijke Weidemann about helping us find a new home in the East Bay, we didn't imagine the process of selling our home in Windsor (Sonoma County) and buying a new home would consume a whole year. But it did, due to an unexpected downturn in residential real estate sales, and we're so grateful Mareijke did't flinch during this protracted period. Mareijke came highly recommended to us by our real estate broker, David Hargreaves, himself a stellar broker in the Windsor-Healdsburg area of Sonoma County. Over the ensuring months, we came to appreciate Mareijke's many outstanding qualities that proved helpful to us in finding a suitable new home in the highly competitive buyer environment of the East Bay Area. Mareijke's extensive knowledge about housing availability and pricing in a wide variety of neighborhoods; ability to determine a neighborhood fit for us; her financial background as a CPA; and most importantly, her attention to our personal desires and needs proved invaluable to steering us to the "perfect" home. During this entire process, Mareijke has answered all our questions about the transaction itself and about getting settled into our new neighborhood. Even after the completion of the home purchase, Mareijke has continued to express interest and support of our transition into our new home. As a result, we have come to regard her as a true friend and professional advisor. In addition to being super smart and engaging, Mareijke is charming, delightful, and fun-loving. You won't find a better combination!

Mareijka was absolutely amazing from start to finish. She was extremely knowledgeable, helpful with everything, and always made us feel supported through the entire process. She was responsive, professional, and genuinely cared about helping us find the right home. We 100% trust her and will absolutely be using her again in the future for all of our real estate needs. We truly enjoyed looking at houses with her and are honestly going to miss it. We are so grateful for all of her help and would highly recommend her to anyone looking for a great agent.

Mareijke, I wanted to take a moment to share how much I appreciated the opportunity to work with you on our recent transaction. Your level of knowledge and professionalism truly stood out throughout the entire process. From the very beginning, your understanding of the market, attention to detail, and ability to guide your clients with confidence made a significant difference. Communication was always clear, timely, and proactive, which helped ensure everything moved smoothly from start to finish. It’s always a pleasure collaborating with someone who is so dedicated to their clients and committed to excellence. I look forward to working together again in the future. Thank you again for your partnership and outstanding work. Best regards,

Inmar was absolutely amazing! From the start we had him doing so much work and not once did I get a bad vibe. As our search for a house continued, we completely changed the area we were looking but that wasn’t a problem for Inmar. He adapted quick while still meeting all of our needs, gave us much needed advice, and helped us score a really good deal. You could tell his experience just through the light conversation on walkthroughs, and when you finally have a moment to sit down he can teach you about anything you want to know regarding real estate. Probably the most important part of my experience with Inmar is that he does not give you any BS. Everything is straight up and if he doesn’t like or think something a good idea, he will express his concern in a super respectful manner. If you need a realtor that will not only listen, educate, and execute but go above and beyond, Inmar is your answer.

This was our second home Inmar has been our agent. He stays on top of every aspect of the sale, including updates, time lines. Highly recommend him!

Inmar has sold me two homes so far. I have enjoyed working with him and appreciate his expertise in the market sometimes as homeowners we have to refer to the professionals and in this case he truly is a professional.

We had an outstanding experience working with Veronica. From start to finish, she was organized, proactive, and truly went above and beyond our expectations. She managed every detail of getting our home ready for market—including coordinating all the necessary improvements—with professionalism and efficiency. Her deep market knowledge and strategic approach delivered a sales result that exceeded what we had hoped for. She was always responsive, kept us informed at every step, and made the entire process seamless. We can’t recommend Veronica highly enough to anyone looking to sell their home.

I reside in another state, I contacted my personal local agent as she knows me well, asking for recommendations. My local agent interviewed several agents in the local area. She chose Veronica for me as she felt that she would be the best fit for me. Veronica was a perfect fit for me and provided sound advice. She really knows the current market conditions and trends. She facilitated a basic home renovation in my absence while I was able to provide input from states away. She really goes way above and beyond and puts the clients' best interests first. Excellent communication every step of the way really kept me at peace. I could not have asked for a better person to help me through the selling process under difficult/unfortunate circumstances. I would rate 10 stars if I could.

Well, I never thought that I would be singing the praises of a realtor! I do not even know where to begin to do justice to the service we received from Veronica!!! I was having difficulty with this whole sale because it had been my childhood home for almost 70 years, but Veronica helped us through the process, by taking baby steps and offering us options to ensure that we had choices. She really has a handle on the market, on what order to do things in and on what buyers are looking for. This helped us figure out where to focus our energies and money. Veronica wears so many hats! Interior decorator, project manager, counselor, psychologist, handy-woman (she has her own tools!) - all that and knowing the real estate laws, etc. She was calm even when we were worried about the market - she was careful not to overwhelm us, and she was always ethical, professional, funny, positive, encouraging, and always prompt about getting back to us for all of our questions (over several months)!!! I cannot say enough good things about Veronica and about her staff!!! She has surrounded herself with incredibly competent people, who are also very prompt about answering any questions or dealing with anything that comes up. Her team of workers are exemplary in every definition of that word - professional, experts, timely, reasonably priced, and prompt. We will be contacting them if we have any future projects!! I wish we had another house to sell - she made it that pleasant of an experience!! If you need a realtor and you are reading this review - look no further - you have found "the one".
