Dr. Kristin Brothers
DDS
As a mom herself, Dr. Brothers knows how important convenience and efficiency are and delivers exactly that at Beach Cities Orthodontics. She grew up in the South Bay and loves to serve her local community through tailored treatments that fit your lifestyle, goals, and budget.
Dr. Brothers has extensive experience with complex, surgical orthodontic treatment and clear aligner therapy. She also likes to make treatment fun so appointments seem less like a chore and more like a fun visit with friends! Whether you’re a kid or an adult — we’ve got a solution for you and guarantee you will love your smile.
Dr. Brothers comes from a dental family, including both her parents who practiced general dentistry in Torrance for over 35 years (now retired), and her husband who is an Oral and Maxillofacial Surgeon. When she’s not in the office, she loves to ski, hike, travel, and dabble in creative projects including painting and video making. You’ll often find her out and about in the South Bay with her husband, two kids, and two dogs — please say hi!
