“Outstanding, experienced, skilled dentist! Thorough and efficient. Referred to him by my previous dentist who was moving out-of-state and told me this is the dentist he would personally use for his oral care. I’ve been very pleased with the work he has performed. Office staff is welcoming and friendly, as well.”
