My wife went to Aspen recently (we didn't know better). They told her that she had periodontal disease and needed an expensive procedure. She was shuffled into a "financing" room before even completing her checkup. While waiting, she Googled Aspen and figured out that this happens to oodles of people, declined, and went to another dentist. No problems detected.

In addition to being a scam organization, we got to see the group of people in the waiting rooms at Aspen vs our current dentist. As you can imagine, the folks waiting in the Aspen waiting room are observably less wealthy and are statistically going to be less able to defend themselves against medical scams.

Evil organization.
