If you are looking for the best orthodontist office around look no further then COOLSMILES!! This is my second experience with braces, my first time was not as pleasant at all(my first time with braces was as a teenager with a different office. I am now a 27 year old adult, so wear your retainer :) ) Already having braces I was picky about where I went this time! From the second I walked into coolsmiles I knew I would have them doing my invisalign. Both offices are extremely nice, with WIFI and coffee and the staff is very helpful and nice The experience has been amazing and my teeth are perfect! I am so happy!! Both Dr. Leon and Dr. David are friendly and extremely helpful. All of their machines and everything they use are state of the art. When I do have kids I plan on taking them back to coolsmiles because the way they are with the kids is amazing. They have games and contests and really connect with the kids(and adults) which is very cool and rare to find!! I have zero complaints and I love my teeth now!! :) Thanks Dr. Leon and Dr. David!! read more

CoolSmiles Rocks! Thank you Dr.Klempner and Dr. Amram for your outstanding expertise and knowledge in Orthodontics. My three children are patients in your port Jefferson office and l would like to personally thank you for making our experiences, simply wonderful! My son came to your office at a young age and presented with a significant underbite , that could have potentially needed surgery to correct without early intervention. With your expertise, knowledge and effective treatment plan, he now has a perfectly aligned mouth thanks to you. We couldn't be happier with the results. I can honestly say you're a wonderful advocate for your patients and want nothing but the best for them. Your staff is beyond amazing and always so professional. If anyone should ask for an orthodontic referral, we're proud and honored to recommend you without hesitation. When it comes to your profession, your truly one of the BEST! read more

The atmosphere at Coolsmiles is warm, caring and professional. Dr. David and Dr. Justin are outstanding experts in their field and the entire team is amazing. I highly recommend this practice to anyone in need of orthodontic care! read more
