Professional. Compassionate. The wow factor for this patient! After solving a dental emergency on my behalf, Dr. Logan took the time to care for each of my dental needs. This included corrective measures given the service of a previous provider. I am exceptionally impressed with her. The Jenkins Road staff is simply a step beyond professional. I look forward to seeing them for each visit. The recommendations worked and I am very, very pleased. Well done!!! View On Google +
