Amy has been in dentistry for over 22 years.  She began her career as a dental assistant in Hawaii and received a great sense of satisfaction giving patients a positive chairside experience.  From the beginning steps as a dental assistant, she transitioned into the practice management area of dentistry.  Amy eventually grew to become a manager of various specialty and general dental practices.
While attending the University of Tampa, she was very eager to become a dentist but decided to take a humanities class in sociology.  It was then that she fell in love with this area of study and switched her degree to Applied Sociology with a concentration in qualitative and quantitative statistical analysis and research.
With her love of sociology and dentistry, Amy expanded her role in dental and accepted a position with a national company as a Technology Advisor for Colorado and Wyoming.  This path eventually led her to realize the impact a coach can make within a practice; thus, became intrigued with this role.
As an coach, Amy values relationships!  She capitalizes on the ability to connect with her clients and teams to attain goals of growing a culture filled with limitless possibilities while assisting with the implantation of strategies to reach the next desirable level of practice growth.
Being active is a core value to Amy; she enjoys snowboarding, traveling, live music and watching her son play college lacrosse.
