Dr. Mongelos is an excellent dentist! I trust him wholeheartedly with all my dental procedures. He is very precise, meticulous, and has a friendly and calm demeanor. He is always prepared for my procedures; I can tell he takes time to plan beforehand. I would 100% recommend him to my friends and family. His assistant and office staff are also top-tier. Note that they are all bilingual English-Spanish speakers too!

I had a great experience with Dr. Mongelos. He was very accurate in evaluating and identifying the root cause of the dental issue I had been dealing with for a while. He provided a clear explanation of the problem and referred me to the right specialist. I really appreciated his professionalism and thorough approach.
