Dental and Surgical Assistant – Collegeville

Sandy entered the dental field right out of high school. She started out at the front desk in reception but then developed an interest in the clinical aspects of dentistry. She trained chairside as a dental assistant and obtained her X-ray certification. After many years of working in general dentistry, Sandy had the opportunity to come and work with Dr. DiGiallorenzo at his periodontal office. She worked with him for five years and learned so much about periodontal and implant dentistry. During that time, she also trained to become a certified phlebotomist.

Sandy left Dr. DiGiallorenzo’s practice for a few years to return to general dentistry but realized that periodontal and implant surgery assisting was really her true passion. Sandy recently had the opportunity to return to work with Dr. DiGiallorenzo and his staff. She is so thrilled to be back doing what she loves. As a trained surgical assistant, she has a passion for helping others and is dedicated to the well-being of the patients under her care.

When not at work, Sandy spends time with her husband, three grown children, and friends, and she loves to travel.

“I can’t imagine a better opportunity to learn the dental business than to be completely immersed in all aspects of the practice while covering my co-workers’ maternity leave. I’ve been impressed with the staff’s patience in training me, and I see the special care everyone takes of the patients. From the initial consultation, I’ve watched the staff shepherd patients through their treatment plan decision-making, scheduling, and the treatment process itself with such compassion and attention to detail. I’ve also found the practice’s whole-person approach to treatment refreshing. It’s clear to me that treatment isn’t just about repairing gums and smiles, it’s about whole body and soul wellness. I’m delighted to be part of the team.”
