Operations Director

Thank you for taking the time to get to know me. My name is Marijane. I started out as a dental assistant and navigated my way through the front office.

I have the opportunity to see beautiful smiles from our patients and I get to lead a dynamic team. In my free time, I love spending time with my close knit & loving family. I also love attending sports games and concerts. "Embrace Obstacles to build the resilience required to live a purpose driven life"
