Great dental office. Everyone was incredibly helpful and explained everything so well. I love that the staff and Doctors volunteer to help people who can't afford dental care. The office is clean and I would recommend it to anyone and everyone. It's worth the drive.

I have been seeing Dr. Costes at the Horizon Dental group since I moved into the area. He and his team are fantastic. They made me feel comfortable and at home. They took time to answer my questions and concerns. I would highly recommend the Horizon Dental group if you need a dentist who is friendly and kind.

The staff are always superb from start to finish. From the moment I walk in the door until checkout I'm made to feel welcome and part of the "family". My hygienist Kristi was very professional and expressed great care with all of my concerns. I suggest Horizon Dental to anybody looking for new dental care or new to the area.

Dr. Costes and his team are amazing. They work with you and let you understand what is going on. I do not have dental insurance, but they offered a discount plan called Ambassador, and I now can afford all the dental treatment I need! The staff is very compassionate and personable! I'm not going anywhere else, this will always be my dental office!

Dr. Costes and his staff at Prescott Horizon Dental Group provide kind, caring, professional and affordable dental care. I am very grateful that they have an office in Prescott and that I can experience all they offer when I need dental care.

Not what you would expect from a small town dental office. I drive all the way up from Phoenix to see Dr. Costes. He and the staff are THAT GOOD! Super clean facility and I am always greeted with smiles and friendly faces. With all my choices in the valley, I still choose to make the trek up to Chino Valley!

I recently had some dental work done at Horizon Dental in Chino. The Horizon team removed my stress with their professionalism and compassion. My appointment started on schedule and the after care recommendations from Darla were much appreciated. Thanks Horizon!!!
- Ted Michael
Dr. Costes was great and replaced my bridge and fixed a loose filling. Fast and painless everyone in his office was friendly and I appreciate how attentive they were and hope I don't need to go back for more than a cleaning but I wouldn't go anywhere else if I need to get work done.
