I got my retainers from the office. It was my second retainers since the removal of braces. My retainers were pretty such cooked. I decided to book an appointment with Kleinrock Orthodontic. They worked with me and my schedule and were very understanding and flexible. When I got there. They scanned my teeth to create a mold. They were so gentle, the office is luxurious and cozy. Everyone was welcoming. My retainers were ready the same day and when I came to get them. They went over the rules and watched me try them on and made sure I was safe and good. If you’re hesitant, let this be your sign.. book the appointment now

I was introduced to Dr. Kleinrock and his office staff over ten years ago for Invisalign and it was the best experience! I got the smile I wanted right before my wedding and ten years later I went back to purchase a replacement retainer and the amazing treatment was still there! I wish I was a patient of theirs when I was growing up!

I was very nervous at first. I’ve had bad dental and orthodontic experiences in the past, but Dr Kleinrock made me feel so comfortable. He explained everything and it worked out even better than I had hoped. He’s very kind and caring. The office staff is wonderful also. Very helpful and kind. I highly recommend.
