Sandy Cadiz

Business Manager

Hi my name is Sandy Cadiz AKA"Sandy Beaches" I am the Business Manager at Schaffer Dental Excellence. I have had the privilege of working with Dr. Schaffer and our awesome team for the past three years. My background started in Hotel Management but I have always had a passion for beautiful smiles. I decided to leave the Hotel Management field 26 years ago and I am happy to say it was one of the best decisions in my life! I love working in dentistry! I myself am a bit of a dental coward so I have great empathy for others that share this annoying fear. It gives me great joy to teach others that with the many amazing advances in dentistry there is no reason to have a fearful experience. I also love that our office is very modern with the latest technology and that we are the only dental office in Southern California that is a green dental office caring for our planet! On a personal note I have two grown wonderful sons and a very handsome 10 month old grandson. I got my nickname Sandy Beaches because I am crazy about the beach and spend a lot of vacation time in Hawaii and just recently discovered how awesome Mexico beaches are! I love boogie boarding and being in the sun enjoying the outdoors!
