Read What Some Of Our Happy Patients Are Saying…

“Great customer service! Very friendly staff. Didn’t have to wait in the lobby for more than a couple minutes, very fast and efficient =) The only thing that I would consider doing differently is to schedule an appointment halfway through to discuss the progress on the braces and what the pt would still like changed from a cosmetic standpoint, and what will be done the following weeks until the braces are off. Overall very great care received, would recommend Mergen Orthodontics to others.”

– Melanie V.

“I got Invisalign from Dr.Mergern and wore them for a little less than 1 year. After getting them off I noticed two teeth were not in the position I was hoping for. Dr.Mergen and the staff rescanned my teeth and were able to get the two teeth corrected without any problems. The 2nd correction was done with no additional charge and I am very happy with teeth!”

– Grant L.

“Everyone in the office was very personable, friendly and enthusiastic to make sure the patient’s needs were met. I was referred to Mergen by my dentist and I am happy to be in their care. Every step of my visit was well prepared and thoroughly broken down by Dr. Mergen and the assistants. I look forward to giving them my business.”
