The "operations" manager, Katie from the Lansdale office is rude. I have used the Hanover office since my son was 7 & never so much as raised my voice despite having to wait 2 hours past our appointment several times for Dr. Mullen. I didnt complain when they called cell phone & cancelled our appointment as I was pulling into the parking lot with my son & had taken half a day off work due to an emergency for Dr Mullen. Then 1 day I had an issue with a bill for orthodontics. I had to send a fax to get someone to call me. Recently I had to cancel my son's appointment but I have tried 2x now to reschedule & got the answering service & left messages. Katie didnt seem to care. Apparently I wasnt calling at the right time and that they cant possibly follow up on all the patients because they have thousands of them. So now my son is 1 of thousands but when they wanted to stick braces on him he was special. Nice. Katie told me she knows who I am &remembers my fax. So I guess the story here is dont make waves, sit like a good girl and dont make Katie mad. she tiold me I can call Hanover to make an appointment-oh cant. Why? Katie said their phone lines are down. Wow. Thanks Katie. Unfortunatley wont be back after this ortho treatment.
