Why Choose an "Orthodontic Specialist"?

SHN Orthodontics offers you Orthodontists, not simply general dentists. An Orthodontist is a dentist who has not only completed a graduate program in dentistry to receive their DDS or DMD (Doctor of Dental Surgery or Doctor of Dental Medicine), but has also gone through a competitive residency at a CODA-accredited Orthodontic program for an additional 2-3 years to be trained specifically in Orthodontics and Dentofacial Orthopedics.

We love Dr. Nissen’s office! I was looking for a second consult for my daughter and we were referred by a friend who had a great experience here. At our first visit, Dr. Nissen was so kind, communicable, and recommended a much less intrusive treatment plan. All of the staff are warm, welcoming, and great at what they do. It is very easy scheduling/rescheduling appointments via phone or even text. The office is clean and organized with a large, very comfortable lobby/waiting area. I definitely recommend Dr. Nissen to anybody looking for an orthodontist!

My daughter absolutely loves Dr. Nissen and the staff. They are all amazing. They are incredibly kind and patient and make you feel welcome. I would highly recommend them to anyone I know. They are the best orthodontist office I have ever been in. Honestly it’s an honor to have my daughter be their patient.

We called Dr. Nissen’s office with an orthodontic emergency as a new patient and Dr. Nissen got us in right away. Her staff and office were very friendly and welcoming. Dr. Nissan is the absolute best, she was so helpful, professional, and kind. She helped us beyond what we even could have imagined. Thank you Dr. Nissen so much from the bottom of our hearts for being so so so helpful and kind to us during such a stressful emergency. Highly recommend Dr. Nissen to anyone looking for an absolutely wonderful Orthodontist.

Our Story

A Family of Mission Viejo Orthodontists

Over 40 years ago Dr. Nissen's father, Dr. James Hilgers, established his Orthodontic practice at our current location. Dr. Nissen is a proud third-generation Orthodontist who enjoys the pleasure of delivering orthodontic treatment in her own unique way! Her hallmarks are great orthodontic vision, attention to detail, and a kind and communicative approach to practice. Dr. Nissen is a local product of St. Margaret's in San Juan Capistrano and after her education in The Bay Area and Boston, she returned to receive her Master's Degree in Orthodontics from Loma Linda University. We look forward to our journey with you!  

What Makes Us Different?

We love our patients and giving them superb care.

To say that we are patient-centric is an understatement. We exist to help you and take great pride in providing you with kind, gentle, thoughtful, and professional orthodontic care. Creating a smile that you are proud of is an honor for us and we enjoy every step of this journey with you!

We pride ourselves on communicating effectively with our patients.

We go the extra mile to ensure a transparent, honest, and well communicated orthodontic treatment. In practicality, this means that we have a "open operatory" policy. We want want you to see our work, understand our method, and to ask as many questions as you can so that you feel comfortable with your patient care. Parents-- we really encourage you to be chair-side with us asking questions and learning all you can about your child's treatment.

Office facility: relaxing, positive, friendly.

Our modern office is meant to be an oasis of relaxation during your visit. Leave your stress and worries at the door, enjoy a fresh coffee, a water, a magazine, or even a Mrs. Field's cookie hot from the oven (don't worry-- it will be our little secret!).

Rich 40+ year history in orthodontics.

Our family has been practicing orthodontics in this very office since the early 1970's. Imagine Dr. Nissen as a little girl watching her father, Dr. James Hilgers, proudly practice his trade. And then see Dr. Nissen as a teenager mixing orthodontic cement for self-ligating. The Hilgers Family and Mission Viejo Orthodontics have been a tradition for over 40 years and we are honored to carry the baton!

Friendly and helpful staff.

Our staff makes this practice what it is. They are talented, kind, friendly, and fun. They will treat you and your children with great respect and care and they just love what they do. And it shows in their work!

Cutting-edge, modern orthodontic technology that we use to treat you.

Great Orthodontics resides at the intersection of training, vision, and technology. We employ the best technology on the market from Invisalign, to the Damon System, to low radiation dental imaging. We invest in technology and your result and experience will directly be impacted by our commitment to that investment.
