It is normal, when unsatisfied customers leave negative feedback and satisfied don't bother leaving feedback. I just want to make sure this site is fair to Marina. I always had great experience and great treatment, much better that in several other dental clinics that I used to go before. That is why I stay with my dentist for many year. Very relaxing atmosphere, familiy-like treatment. Marina is Great. Receptionist is great. They really care about custoners, not about customers money, which is extremely rare. Thank you!
