About Atlas

TWO SPECIALISTS. ONE SHARED COMMITMENT TO EXCEPTIONAL RESULTS.

Atlas Orthodontics and Periodontics is a boutique, dual-specialty practice led by husband-and-wife specialists Dr. Jason Zimmerman and Dr. Fernanda Barona. Together, they provide advanced orthodontic and periodontal care in one comfortable Richmond Hill office.

Because our specialists can collaborate, your treatment can consider more than the appearance of your teeth. Alignment, bite function, gum health, bone support, and long-term stability can all be evaluated as part of one coordinated plan. Here, you are never treated like a number. Your questions are welcomed, your options are explained, and every detail matters.

GETTING STARTED

THREE STEPS TO SPECIALIZED CARE

Whether you are exploring orthodontic treatment, concerned about your gums, or considering dental implants, our team will guide you through every step with clarity and care.

Request Your Consultation

Tell us what brings you to Atlas: orthodontic treatment, gum concerns, missing teeth, or a professional referral. Our team will arrange the right type of first appointment for your needs.

Meet Your Expert Specialist

We will complete any necessary digital records, perform a thorough examination in a private treatment room, and take time to understand your concerns and goals.

Receive Your Personal Plan

Your specialist will clearly explain the diagnosis, recommended options, expected timeline, and treatment fees so you can make an informed decision with confidence.

Complimentary initial orthodontic consultations are available. Certain consultations and periodontal appointments may involve a fee.

Dr. Zimmerman’s process includes digital scans, photographs, digital X-rays, a private examination, treatment recommendations, and a fee estimate.

REAL PATIENTS. REMARKABLE RESULTS.

"WE NEVER FELT RUSHED"

I just finished my journey for braces. It was a long process with the expander first. But I enjoyed this long process and liked every moment (my favourite part was picking a colour every appointment 😝). Dr. Zimmerman Is the best doctor and the nurse is so sweet. Everyone there is really nice and welcoming. I felt very comfortable there and was happy with everything. I love my teeth now there perfect and so straight. Dr. Zimmerman did a really good job on my teeth and spend a lot of time to make sure everything turned out great and also made sure if I liked the way my teeth looked. I’m so happy everything went well and I had such an amazing journey with them and everyone at Atlas Orthodontics and Periodontics!!

"WE NEVER FELT RUSHED"

I had two gum grafts from Dr. Barona and I can only say great things!! From the consultation to the follow-up I have been taken care of. I was really nervous going into my first gum graft but Dr. Barona and the rest of the team made my experience so relaxed and enjoyable so I knew that for my second graft that would be the case as well! The root of my tooth is no longer seeing the light of day and for that I am so grateful!!! I would recommend Dr. Barona to everyone I know, I have never been more comfortable with a dental professional. Also shoutout to Dr. Zimmerman as well, gonna be getting my braces next and so far from the consultation I know that experience will be enjoyable as well! I cannot recommend this place enough! Thank you Dr. Barona and Dr. Zimmerman for being so caring and professional!

I want to give a huge thank you to Dr. Barona and all the staff at Atlas for their support in my gum grafting journey. Dr. Barona is awesome! Dr. Barona has been amazingly supportive throughout this process with fantastic technical abilities, keeping me informed at every step, all while being compassionate and caring.

"WE NEVER FELT RUSHED"

Dr. Zimmerman is outright the greatest orthodontist I have ever been seen by. He is honest, welcoming and such a perfectionist; he looks at every minor detail and I love how involved he’s kept me throughout my braces treatment. He will make sure one loves their teeth/ smile after the braces come off. Me and my husband both got braces form him. Plus, the entire staff at Atlas Orthodontics is so warm and friendly. They make sure the dental visit is comfortable and never hesitate to offer some complimentary drinks !

"WE NEVER FELT RUSHED"

I had an excellent experience with this practice. The entire team is warm, professional, and truly cares about their patients. They take the time to explain everything clearly, make you feel comfortable, and deliver top-quality care from start to finish. The office is clean, modern, and very well-run. I’m grateful for the outstanding service and would highly recommend them to anyone looking for orthodontic or periodontal treatment.

"WE NEVER FELT RUSHED"

Can’t say enough about Dr. Barona.
I have been dealing with her through an implant process over the last 18 months. I always feel welcomed and comfortable. I’m not a big review person and when I do it’s truly becasue I think it’s well deserved. She is extremely thorough, competent and ensures you fully understand what’s happening in real time.
I now have my son seeing both her and Dr. Zimmerman and confident he is in good hands.
