After writing this review, I was contacted by a Midwest Dental representative to discuss my experience. Carla was incredibly attentive and helpful -- she gathered information from me and then went to visit Dr. Spiewak's office to discuss the issue with them. After doing so, she promptly called me back and offered to cover half the services now billed. While the experience overall was still frustrating, I really appreciate how quickly someone at Midwest Dental responded to my concerns and willing they (including Dr. Spiewak) were to accommodate me given the circumstances. Hopefully, my experience was an aberrant one, but I really appreciate how professionally and promptly Midwest handled my claim (even if the dental assistant who helped me initially was much less helpful).
