Nicole Mariniello, BS, RDH


As a Colorado native, I enjoy all things outdoors! I was granted a bachelor’s degree in Biology from Metropolitan State University and have since earned my license to practice dental hygiene. I take pride in my patient’s experience, oral health and individuality. I actively seek knowledge and opportunities to educate others. My goal at Littleton Family Dental is to establish a relationship with you and your family while promoting optimal, comprehensive care!
