My son and I were excitedly greeted by Lori, who provided a facility tour, explaining their culture and ways of practice in a very friendly and... inviting way. She treated us like stakeholders. I felt like I was there to buy a McLaren and she made us feel very knowledgeable and informed throughout the info gathering, and decision making process. Dr. Flanagan was equally as confident and genuine about my sons outlook for his teeth. They made us feel like part of a highly functional, process driven team.read more
