Sales Associate

Get to Know Me

Mariko, originally from Japan and raised on the Big Island of Hawaii, moved to California in 2001 to attend college. She graduated from Sonoma State University with degrees in Kinesiology and Business Administration. During her senior year, Mariko started riding and racing road bikes, which led her to work at a local bike shop while studying for the MCAT to pursue sports medicine. However, fate intervened and she met her future husband, with whom she opened a bike shop in 2008. Small business ownership has taught her valuable lessons about the dynamics of exchanging goods, services, time, and money. 
Over 20 years of living and cycling in Sonoma County has developed a deep knowledge of all the area has to offer, in both recreation and housing. During the process of searching, touring, bidding, and working with their REALTOR® on their first home purchase, Mariko realized that real estate suited her entrepreneurial nature and gave her the opportunity to exercise her resourcefulness, empathy, and attention to detail. 
Mariko's passion for real estate makes her an excellent agent for anyone looking for a personalized and positive experience.

Mariko and Heather were absolutely amazing. They sold my mom’s home when she was transferred to a residential care facility and was forced to liquidate to pay for her care expenses. It was a very challenging time for our family. These professional women went above and beyond for us. They weren’t afraid to roll up their sleeves and attend to the unpleasant details that we were unable to manage. I am So incredibly grateful that we had them in our corner. They were very knowledgeable and efficient and sold the home in record time. We will be referring everyone we know to their services.
Working with Mariko was amazing! Very clearly was able to communicate and was available when needed. Definitely recommend Mariko for a high quality services!
Long review short — Mariko is the best in Sonoma County to work with! Being new to the area in Santa Rosa we couldn’t have found a better agent than Mariko. She understood our wants, needs, and hopes better than we did ourselves. She helped us find the neighborhood that fit us like a glove and made us feel right at home. As first-time homebuyers a process that could have been very scary (and was from time to time) felt easy and comfortable. When we raised a concern she worked with us to address it. She advocated for us throughout the buying process and helped us stay comfortably within our budget. Mariko went above and beyond coordinating with contractors to help us set up our inspection and even went as far as helping us get the immediate work done before we moved in. I would recommend Mariko to anyone in need of a realtor. She is the best of the best and there is no one we’d rather work with now or in the future. Thank you for everything, Mariko!
Mariko is absolutely amazing to work with. I felt very comfortable with her immediately. I had never navigated selling a house before, and she took all the fear out of it. She explained everything to me in depth, answered all my questions, and was always available if I reached out. I highly recommend her, and will be working with her in the future for all my realty needs!
Mariko is a great realtor! She brought us a great offer and was very diligent in making sure the transaction closed. Bravo!
In the fall of 2025, Mariko handled the sale of a home for me in Petaluma. “Handled” doesn’t even begin to capture the extraordinary service she provided at every step of the journey. As an estate sale managed from out of state, the process had the potential to be arduous and complicated—but it wasn’t, at all, and that is largely thanks to Mariko. In addition to expertly managing all aspects of a typical real estate transaction, Mariko essentially acted as our general contractor, coordinating everything needed to prepare the house for sale. This included managing vendors for cleaning, painting, landscaping, inspections, minor updates and repairs, hauling, and more. She also made sure that whenever possible, items were donated or sold rather than discarded. Throughout the entire process, Mariko was proactive, timely, and transparent in her communications, exceptionally well organized, and consistently ensured that whatever needed to happen actually happened. I would happily work with Mariko again and wholeheartedly recommend her without any reservations whatsoever.
We absolutely love working with Mariko at Corcoran Icon Properties. As a local painting contractor, we truly value partners who are responsive, organized, and easy to collaborate with, and Mariko consistently delivers on all fronts. She is always quick to respond to questions, communicates clearly, and stays actively involved throughout every stage of the process. We’ve had the pleasure of working with her on over four projects, and each one has been smooth, efficient, and well-coordinated. Her attention to detail and hands-on approach help keep projects on track and ensure great results for her clients. Beyond her professionalism, Mariko is genuinely a pleasure to work with, and we highly recommend her to anyone looking for a knowledgeable, reliable realtor who works seamlessly with local professionals.
I've had the opportunity to photograph and film several of Mariko Leilani Buchholz's listings, and each experience has been outstanding. Mariko is incredibly organized, professional, and attentive to detail. What always stands out to me is how well-prepared her properties are before a photo or video shoot, allowing each home to truly shine and make a great first impression. Her dedication to presenting her listings at the highest level is evident in every property she represents. If you're looking for a knowledgeable, hardworking realtor who genuinely cares about her clients and their homes, I highly recommend Mariko.
I am so glad that I was referred to Mariko. Her listening skills are top notch. She was able to succinctly summarize my home essentials from our initial conversation. The process was clear and painless due to Mariko's organizational and communication skills. She set up and accompanied me to an appointment with an official to gather more information about the property. Most importantly, she handled many meetings with contractors while I was at work. I am grateful to her dedication in providing a positive home buying experience. I love my house!
Mariko is a superb realtor. She is reliable, available and a great communicator. We never felt pressured or rushed to make decisions, yet she moved things forward very quickly as soon as we were ready to make an offer. She has a great deal of knowledge about resources in the community and has countless connections to reliable service providers in the area. She also seems to have the best interest of her clients at heart vs just trying to make a sale. She is honest and transparent and really wonderful to work with!
