A personal note from Dr. Sidney R. Gallegos

July 24, 2023

As of August 1, 2023, I will be turning over the ownership of this practice to a wonderful group of dentists, Happy Kids Dentistry, who share the same practice values of oral health care for pediatric and adolescent patients as I have for the past 43 years. My gratitude to all parents, care takers and patients who have entrusted our practice to be a part of your child's care.

Happy Kids Dentistry will continue to provide top quality children's dental care for all patients. The same ancillary services such as, In-office General Anesthesia, Hospital Care, Special Needs Patients, will be available. It has been my objective to find someone who will continue the same practice philosophy and maintain the standards of excellence that our practice is known for. I'm confident that Happy Kids Dentistry will provide that legacy of quality service for our patients.

I can't express enough how my career has been enriched by all the experiences and learning you have brought me. I have been blessed with your presence. I wish all of you wellness and happiness.

For Better Dental and Oral Health Care and Well Being,


Dr. Sidney R. Gallegos
Diplomate, American Board of Pediatric Dentistry
