His practice, Peak Performance, uses an honor-fee system (or “the box on the wall”), which allows patients to determine a set weekly payment based upon what they can afford. This concept has been in existence for more that 30 years and was used exclusively when chiropractic work was a cash-only business and, in some places, illegal. Miglierie feels it is the purest form of payment, and allows an entire famiy to come for spinal checkups on a regular basis, no matter what the can afford.
