"I've used Granite Orthodontic Labs for the past 10 Years and am very satisfied with the appliances provided.  They always fit with little to no adjustments saving me time at the chair.  Jeff is always on time and communicates effectively with my staff on a regular basis."

Spectrum Dental Group, Dr. Wayne Wu D.D.S.

Granite Laboratory Is the most efficient orthodontic lab we have dealt with.  We always received consistent quality workmanship since we began doing business with them.  We have been very pleased with the attention to detail in every aspect of the removable appliance process.  We always receive our appliances back on time and we wouldn't hesitate to recommend Granite Lab to other practices.  Than you for giving this office this opportunity to express our appreciation.
