The office manager who handles billing is incompetent when it comes to handling claims. She doesn't file them with insurance, she won't return phone calls, and doesn't do her job. So unless you like to pay out of pocket, instead of using your hard earned insurance, don't go to Wigwam Dental.
The billing situation is unfortunate because Madonna is an excellent hygienist; thorough, educated and simply lovely.
Update: My basic cleaning is covered by my insurance, but after numerous calls to the office manager (who I was referred to for billing) she would not submit the claim or return my phone call. The reception staff told me they couldn't help me either. Wigwam Dental does not work for their patients. I now go to Dr. Tiffany Jackson at Windmill Dental, who earn a 5 stars rating from me.
