To Our Panorama City Patients:

We are so sorry that our office closed suddenly. We wish that we could have given you more notice, however, we were only given one week to leave our beloved dental home. We appreciate all the messages of concern, and would love to continue serving you. If you are willing to make the "paysal" to Diamond Bar, we would love to continue being your dental family.

I've been coming to Horizon dental for years. The Landigs offer a personal and professional experience. The office is always clean and welcoming. I always feel confident I have received the best care possible at the end of my visit.

Professional, friendly, and excellent service. Going to the dentist has never been as awesome as this, especially with the welcoming staff.

I've been going here for more than 5 years and I've been treated really well. I've had cleaning, root cannal, and wisdom tooth removal done here and it has exceeded my expectations.

Thank you Dr. Landig, Dr. Myoli and all the staff who makes this place really awesome!

Kevin C.

I've known the Landig family for years. Clean and friendly environment. Check in was fast and teeth cleaning was painless. I recommend Dr. Myoli and her family for all dental services. Definitely will be coming back!
