Jonathan Ng

Licensed Realtor


Jonathan Ng epitomizes hard work, devotion, and passion in all that he does. Born and raised in the Bay Area, he started in sales at the age of seven selling chocolate. His family and friends would tell you, "that Jonathan is always selling something". Jonathan took that drive to sell and earned a degree in Marketing. His passion for homes came when him and his wife purchased their first home. During the home-buying process, he was able to learn the ins and outs of real estate, but it also made Jonathan realize that there's a lot to soak in for first-time buyers. As your agent, Jonathan wants to be able to ease any worries you may have. Feel free to call or text 707-342-1991 with any questions or concerns.
