Meet Dr. Harrison Siu

My goal is to provide exceptional orthodontic treatment for all my patients, while also ensuring that they have a fun and pleasurable experience. As an orthodontist, I can greatly improve the lives of my patients, and I love seeing the happiness and joy they have when they look into the mirror for the first time at their new smile. My experience with treating complex cases helped me realize that orthodontics is much more than just straightening teeth. It's about getting to know each of my patients and their needs, and holistically improving their tooth, jaw, and facial harmony for improved aesthetics, health, and quality of life.

My appreciation for dentistry began developing when I had braces as a teenager, and I realized the impact orthodontic treatment has on self-esteem and confidence. I find it extremely gratifying to be able to provide for others what my orthodontist gave to me! I continually strive to stay on the cutting edge of techniques and methods in the industry, and I'm proud and honored to provide top-quality orthodontic care and specialized orthodontic treatments, including braces and Invisalign® clear aligners, to people of all ages in Marinette and the surrounding communities in Eastern Wisconsin.

In my free time, I love spending time outdoors and playing basketball, soccer, badminton, mountain biking in the summer, and snowboarding in the winter. My family and I are originally from Toronto, Canada, where I grew up playing the violin. I’ve now started teaching myself how to play the guitar, and it’s been quite the fun challenge! On the weekends, you can usually find me spending time at one of the awesome local coffee shops with even better company.
