Meet Dr. Cassandra Zirbel


Orthodontics is such a rewarding career. It’s an amazing feeling to see the excitement and joy our patients have when they transform their smile into one they are proud to share. For me, that is what orthodontics is all about: making long-lasting, positive changes in the lives of my patients. When I see a patient start to realize that their hard work is paying off, as we show them the progress that they’re making, and their self-esteem begins to increase, I feel fulfilled. I know that having straight teeth and a beautiful smile means the patient is going to have a better, healthier, happier life, and being part of that process is rewarding.

I feel incredibly lucky to have the ability to form long-term relationships with each of my patients and their families. Because my emphasis is on creating smiles based on a patient’s unique needs, I spend time with each person, learning about who they are and their passions and interests. Over the course of treatment, as I see a patient at each visit, I get to hear about their latest adventures, successes in school or in sports, and what’s been happening in their lives. I look forward to their visits as a chance to not only check up on how their treatment is progressing, but to hear how they’re doing.

My Education and Commitment to Continuing Education

After high school I attended the University of Minnesota and majored in physiology and then enrolled at the University of Minnesota School of Dentistry, where I was awarded my Doctorate of Dental Surgery. This was followed by studies at the University of Texas Health Science Center in San Antonio, where I was chief resident in orthodontics. Then it was on to the University of Texas Graduate School of Biomedical Sciences for a Master of Science in cellular and structural biology.

I love being part of a field which requires me to be a lifelong student. I am committed to providing the best care to my patients, and this can only be achieved by continuing to learn and expand my skills, through participation in continuing education courses. I am a member of the American Association of Orthodontists and the American Dental Association, both of which provide me with access to meetings, lectures, and relevant oral healthcare literature.

I was born in St. Paul, grew up in Cottage Grove, and graduated from Park High School. My husband Justin, myself, our son Rylan and daughter Emmerson now call Woodbury our home.  My family is my first priority, and I love spending time with them. Being outdoors is also important to me, whether I am playing a round of golf, fishing, or being on the water. Travel is wonderful, too, as I love to experience new sights, sounds, and cultures.
