Dr. Elmassian implanted some crowns for me a few months ago. I do NOT recommend this dentist, as he is unprofessional, incapable, and technically inexperienced. I needed to seek help from other dentists because he did such a bad job. Three other dentists were appalled at how poorly he had attached the crowns in my mouth. He didn't believe me when I said a board-certified dentist had performed the work.
