Laura Beard, Communications Manager

Laura joined Johann Prosthetics in 2021 as the Communications Manager. She accidentally got into dental about 6  years ago just helping a friend out in her office and found a change of career.  Laura has since been at the front desk of general dentistry, ran an Ortho practice and did marketing for Oral Surgery.  She loves learning all the aspects of these different offices and roles. Laura's favorite part of this new role is building patient relationships and great continued relationships with our referral offices, ensuring that each patient receives the best care possible.  

Laura has lived in every time zone, and grew up on the East Coast but settled here in Colorado 11 years ago with her 3 almost grown kids and 2 dogs. She loves paddleboarding, hiking, camping and jeeping with her kids and friends.

He earned his CDT certification in 1985; however, his education in the field is forever growing to stay up-to-date with growing trends and new technology. Examples of this recent growth would be his expertise in flexible partials along with the latest implant technology along with learning how to print and scan digital models.Mike’s love of the dental field stems from his years losing teeth as a hockey player (now passionate trail runner) and he is honored to be a part of the talented team at Johann Prosthetics.
