Dr. Mark is trustworthy, kind and professional. He explains the procdedure to you in detal and makes sure you know whats done and why its done. He won't make you get any work done unless you need it. I had this experiece before, and I know the difference. He is a great doctor, makes sure you are comfortable during the procedure. Prices can be negotiated, but after doing research, I know that his is very reasonable to start with. Inna at the front desk is a nice girl, assistant is fine too, but most important person there is Dr Mark. Make sure your appointment is with him and not with an associate, and you will NEVER go to another dentist. BEST DENTSIT IN LOS ANGELES,!
