Best experience by far. Thank you Dr. Seini!!!! I literally prolonged taking out my wisdom teeth because I was uneducated about the effects of not taking it out that I caught a severe infection that caused me to be in extreme muscle pain in my neck, ear, jaw. Dr. Seini was THE first to reach out to me & was able to schedule me in the next morning AND on a Saturday! I was so relieved. She was thorough & was very transparent about my situation and helped me right away! She helped me pull out 4 of my wisdom teeth & after a week of recovery, I feel SO much better. I'm really glad Dr. Seini was able to contact me as soon as she could & my whole experience with her has been so good. I've avoided the dentist (clearly) because I'm scared of them, but Dr. Seini is so patient, caring, and most importantly transparent with dental care. I have felt so comfortable with her throughout this process & her staff is amazing as well! I cannot thank her enough for helping me!

Nothing but great reviews for Dr. Seini and her team. I first called for an emergency crown replacement (on a plane during my way back home from a work conference). It was after hours so I didn't leave a message when there Was no answer. But, Dr. Seini called me back! I've never had anyone done that. I told her that my crown got loose and she was able to schedule me in for the next day! She fixed my crown and also caught me up on all my Dentistry needs since I have not been to the dentist in awhile due to COVID. She did amazing work on my teeth and I have a much brighter smile :) Dr. Seini and her team are also very warm and welcoming. I definitely recommend!!!

I recently had an implant, and a new crown replacement done by Dr.Samira. The process took 5-6 months since the implant needed to heal. I have to say the final results was over exceeded my expectations. I'm very pleased and happy to say that, I can smile normally again. I also had some other minor treatments done like deep cleaning, whiting, and that I'm very pleased with the results. I highly recommend their services.
