Our Team


Mari Sawtelle | Founder & President

In 1983, Mari started her orthodontic career as a lab tech and orthodontic assistant. After several years and at the urging of her doctor, she entered the orthodontic sales arena. Her first sales position was with Johnson & Johnson / A Company, and over the course of the next decade, she was promoted through the ranks to the top level of sales as a company trainer. She continued with Ormco for several years after a merger.


Mari was offered an opportunity to be part of the founding team at Align Technology, handling the entire state of Texas and managing Align’s lead market for advertising in Austin, as well as acting as the company trainer. She then became a rep for GAC / Dentsply, where she set a company sales record her first year. 


As a sales representative for four of the largest orthodontic manufacturers, Mari saved time and money for the offices she called on by teaching them how to inventory, maintain appropriate stock levels, and put together ordering systems. She worked with ordering assistants and doctors, recommending products that balanced quality and value.


After more than 25 years in the field, mastering the orthodontic industry from the vendor side in support of her doctors, Mari was recruited to join a 12 doctor multi-practice company as Director of Business Development and Purchasing. Here she developed an expertise in the practice side of the business, creating the inventory formulary, negotiating pricing, establishing the inventory system and infrastructure, and building the new office template for a multi-million dollar ortho enterprise. During her tenure, she was responsible for three office openings and saved the company millions in overhead.


In 2012, Mari founded Sawtelle Consulting, and over the next two years analyzed 45 orthodontic practices, gathering valuable information, which lead to the creation of Mari’s List®. The buying group started out with six companies and over the last seven years has grown to more than 130+ companies and 2100+ members.


Mari lives in the beautiful Texas hill country with her husband, Matthew, and their pack of dogs. She makes a mean pot roast, enjoys good wine, and loves what she does.

Cory Garrison | Trainer

Cory’s ortho career began in 2005 when he joined Sun Orthodontix, a multi-practice company with offices in Texas and New Mexico. Starting from the ground up, Cory worked as an Orthodontic Assistant in order to learn the instruments, products, and lingo through a hands-on approach. Under Mari’s guidance, he quickly moved up the ladder into the inventory and purchasing department.


He learned competitive pricing, negotiating skills and how to select high-quality, high-value, state-of-the-art products. As Mari’s Inventory Control Manager, Cory maintained a $1 million+ orthodontic inventory for seven practices. As Sun Orthodontix expanded, he and Mari opened several new offices together, handling the purchasing of nearly every aspect of the new office, from operatory chairs to equipment. Cory is a master of how to shop effectively!


Cory has the best sense of humor and keeps our team laughing. He lives in Gulfport, Mississippi, and is a super proud dad with two sons who were recently awarded college baseball scholarships.
