Monarch Dental review: Office management / scheduling

I'm a new patient, so I had my original consult and a follow-up appointment for dental work. The short version is this office has no office manager, so appointments, waiting and overall time spent there is absurd.
Ex 1: First visit, I had all paperwork filled out in advance to save time. I still waited in the lobby for 45 minutes before being taken back. After that, the visit ran long and I was late for work. Keep in mind this was for an initial consult, x-rays and teeth cleaning. They were so behind schedule, I opted not to wait another hour for teeth cleaning and left.
Ex 2: I scheduled my follow-up visit and was told 90 minutes. The visit took 5 hours. Apparently they overbooked and are understaffed. They would work on me, leave for 10-15 minutes, do some more, leave me again, etc. I was late to work again and docked pay because they lied about the time and took way too long.

The Pros: Staff is friendly, dentists do a great job.
The Cons: They don't have a local office manager, they're scheduling stinks, they're understaffed and can offer nothing but excuses when they go over their allotted time.

I got a manager (Sandra Contreras) on the phone and received an apology, but they refused to reduce the bill for this screw up. I will not be returning to this dentist office. Just not worth the hassle and wasted time.
