  • "I originally had an appointment at another dentist office this morning, but due to snow and traffic they cancelled my appointment so called around to different offices for a Saturday appointment. Initially I was told that I could only have a ortho consult for Invisalign done today but somehow the amazing team here was able to fit me in for a cleaning, x-rays and take care of all of my dental needs and questions in the same day at the last minute. Thanks for taking great care of me today!"
