Andrew Johnston, RDH: I am a Registered Dental Hygiene graduate from the Yakima Valley Community College Dental Hygiene Program in 2009. I hold three degrees including a Bachelors Degree in Business Management and currently working towards my MBA. First and foremost, I am a husband and a father to my wife and three children. When I have time to get away, I regularly lecturer at dental hygiene programs throughout the USA. I also speak at dental hygiene societies and associations. In 2013, I was asked to be a faculty member for DDS - Dental Development Seminars. My role includes mentoring and instructing dental professionals in technique driven delivery of local anesthetic. As the only hygienist on the faculty, I focus on being a liason between the dentists and hygienists to build trust and understanding between the two groups by helping ensure competency, accuracy, and confidence in the hygienist attendees.   I also write, blog, and am a regular contributor on Hygienetown.com. I write articles for a number of publishings including my own blog http://andrewjohnstonrdh.blogspot.com. I am a regular panel member for Mark Frias' roundtable discussions and have been interviewed by Dr. Howard Farran for his Dentaltown podcast. In the future, I hope to be lecturing at regional and national conferences on my local anesthesia review course. My "Charitable Dentistry" lecture is a compilation of many years of mission trips and charity work throughout the world. I have volunteered my time and efforts with local programs such as the Union Gospel Mission's dental office, YVCC sealant days, the Boy Scouts of America, and as a coach for the local parks and rec teams. Nationally, I have consulted for dental teams and offices interested in learning how to participate in charitable ventures. I provide research that is specific to the desires of the team at no charge to them. Internationally, I have been on mission trips in the Philippines, Guatemala, and the Dominican Republic.   Linda Douglas, RDH: Linda M Douglas graduated as a dental hygienist from the Royal Dental Hospital in London, England in 1982.
