Why are you proud to be a dental hygienist?
I’m proud to be a dental hygienist because our profession goes far beyond providing clinical care. We are educators, advocates, researchers, and often the professionals who build long-term relationships with patients and help them understand the connection between oral health and overall health. Dental hygiene gave me the opportunity to combine my background in dentistry with my passion for prevention, education, and patient care, while also opening doors for me to contribute to research and the education of future dental hygienists.
Who or what inspired you to pursue dental hygiene?
My journey into dental hygiene was a little different. I originally earned my Bachelor of Dental Surgery in 2017 before moving to the United States. Starting over in a new country was challenging, but it also gave me the opportunity to discover dental hygiene and see the profession from a completely different perspective. What began as a new pathway in dentistry became a profession I truly fell in love with. I realized that dental hygiene allowed me to stay connected to patient care while also pursuing my interests in education, research, prevention, and advocacy.
What does being a CDHA member mean to you?
Being a CDHA member means being part of a community that gives dental hygienists a collective voice. My involvement with CDHA has allowed me to connect with other professionals, continue learning, serve my local component, and advocate for the advancement of our profession. It has also shown me how important professional involvement is. Our profession becomes stronger when hygienists participate, share their perspectives, mentor one another, and advocate for the future of dental hygiene.
How do you hope to make a difference in the profession or your community?
I hope to make a difference by connecting clinical practice, education, research, and advocacy. As an educator, I want students to feel supported not only academically and clinically, but also as individuals navigating the challenges of professional education. As a researcher, I want to bring attention to issues that may be overlooked but directly affect students’ well-being and success. My recent research on food insecurity and housing instability among dental hygiene students is an example of that goal. Ultimately, I hope my work encourages meaningful conversations and helps create a stronger and more supportive profession for the next generation.
What dental hygiene issue would you like your voice to help change?
One issue I want to continue bringing attention to is the well-being of dental hygiene students and the barriers they may face while completing their education. My research examined food insecurity and housing instability among dental hygiene students, challenges that can remain invisible even while students are expected to meet demanding academic and clinical requirements. I hope to continue using research and advocacy to help our profession recognize these challenges and explore ways to better support students throughout their education.
What advice would you give to a future dental hygienist?
Stay curious, get involved, and never limit yourself to what you think a dental hygienist is “supposed” to do. Clinical practice is only one part of this profession. There are opportunities in education, research, advocacy, leadership, public health, and so much more. Take opportunities even when they feel outside your comfort zone, find mentors, ask questions, and keep learning. Some of the opportunities that shaped my career began simply because I was willing to get involved and try something new.
