Cassi M. Warren, RDH

Dental Hygienist

“Here at Bella Smiles alongside Dr. Rojas and our team since 2014, I’m a happy hygienist, married to my high school sweetheart and best friend. I’m beyond thankful to be the mama of our daughter and son. I strive to meet our patients with sincerity and compassion. My hope is to educate individuals based on personal need during their short time with me and to put their minds at ease. A comfortable and smiling patient at the beginning and end of each appointment is my goal. As a local valley resident having resided in La Quinta, Palm Desert, Rancho Mirage & having been born in Palm Springs, it gives me great pleasure to provide care for my fellow desert dwellers; those full and part-time. Obtaining optimal health, starting with a happy mouth leads to a healthy heart and a happier you!”
