I have only been to the office a couple of times myself, and have been very satisfied with Dr. Alonso's professionalism and skill. As well, Leticia is a terrific office manager and always makes things pleasant, as simple and hassle-free as possible.
This appointment was for a routine cleaning, and I was paired with a hygenist that was nice enough, and started on time. However, the she was either distracted, in a hurry, or simply incompetent because at each stage of the cleaning she did a very poor job, clumsy and incomplete. Very different from my past cleaning at this office.
I would most definitely recommend Dr. Alonso's office, but I will absolutely confirm who my technician will be in advance, and ask to change my date/time to avoid getting her again.
