Janzen & Chwa Orthodontics

Janzen & Chwa Orthodontics is a family-owned orthodontic practice in Northbrook, IL, with over 60 years of history serving the North Shore community. Founded by Dr. Ernst Janzen, the practice was carried forward by his daughter, Dr. Marita Janzen, alongside her partner, Dr. Kyint Chwa. Today, Dr. Kyint Chwa continues that legacy alongside his son, Dr. Evan Chwa, bringing three generations of ownership together to blend decades of trusted, personalized care with a renewed focus on modern systems and technology.

We provide comprehensive orthodontic treatment for children, teens, and adults, including traditional braces, clear aligner therapy, phase 1 (early) treatment, and growth monitoring/observation programs for our younger patients. Using digital scanning, 3D imaging, and 3D printing, we deliver precise, efficient treatment planning tailored to each patient.

As we look ahead, we're investing in the systems, technology, and team development needed to grow thoughtfully, expanding access to care in our community while staying true to the trusted, family-first values this practice was built on.
