I had a very bad experience with this dentist. Dr. Martinez-Vargas first of all showed up late, and then he treated me with a lack of respect. During my exam he complained that I did not open my mouth wide enough and instead of just asking me in a polite fashion to do so, he accused me of "having something wrong" with me, and help up a mirror repeatedly to show me? His perception of my open jaw was not only inaccurate, but his tone and behavior toward a very little thing was inappropriate. After my exam I had some questions and he was not very informative with his answers, and was dismissive. Overall I felt very uncomfortable going back there and will transferring to another dentist.
