About Us

A Family of Smile Designers

Our smile designers love what they do, but creating great smiles isn’t all they do. The Smile Agency team is a group of people that have vision, passion and precision skills. They treat you like family from your first visit to your last. Led by Dr. Karen E. Guinn, a Board Certified Orthodontist who brings thirty years of experience to the table, there isn’t anything the team can’t do!

Meet Dr. Guinn

Doctor Karen E. Guinn is a Board Certified Orthodontist, and has been providing orthodontic care and changing lives one smile at a time for over thirty years. Residents of Pasadena have come to know her as the “Green Street Dentist” since her flagship dental office is right on the iconic Pasadena road, Green St.

She recognizes that each patient has specific needs, and strives to provide the best orthodontic care for every one of her patients at either one of The Smile Agency’s convenient locations in Pasadena and W. Covina. Her goal is to give you a braces lift without a face lift, and to help you live life smiling!

ABO Certification - Why It Matters

Dr. Guinn is a Board Certified Doctor. This means she has achieved the highest level of certification available in the orthodontic profession. It’s a distinction earned by fewer than 30% of all orthodontists.

Being Board Certified is just one more way The Smile Agency goes the extra mile to assure that our patients receive the best care available.
