Ravage Stryczny: Territory Sales Manager

As a twenty-five year experienced Registered Dental Hygienist (RDH) I have had the opportunity to use my skills both in practice and academia. My passion for the dental field has its roots grounded in my early experience as both a student and practicing RDH. Through these experiences, I have been able to develop a keen sense of the patient’s needs and I have developed the ability to communicate effectively as a liaison for patient/dentist/practice relationships. This, in turn, provided for a much better overall experience for all involved during dental procedures and ongoing relationships.

I was able to move from a clinical application to the application of knowledge transfer to faculty, students, lab technicians, and dentists. Professionally, the move from clinical to commerce has increased my overall knowledge of our industry and helped me to better understand the challenges of communication transfer from commerce to education. I know that my commitment to the industry and associated experiences, the customers I serve at the various dental schools, and practices that they support have proven to be lessons learned but not forgotten.

Two years ago I decided to challenge myself; to challenge those I contact and to challenge the industry by advancing my education. I enrolled in the University of Bridgeport’s Masters of Dental Hygiene Program. I wanted to push the betterment of healthcare through education and training, both of myself and those I touch in communities and cities across our great nation. I look forward to continuing my journey of dental advocacy and commitment as I complete my master’s degree and fuse my past with the future to further the role of the dental field in many capacities.

In my spare time I enjoy spending time with my family, boating, gardening, skiing and hiking.
