Very knowledgeable and also very caring I felt so comfortable when talking to her about anything and she listens very well to you and explains everything until you understand
February 25, 2021Danny D.Verified patient
Dr. Chaglassian is pleasant, professional and thorough. She answered my questions, and seemed willing to go above and beyond for her patients. I will be retuning to see her as I think she is a strong advocate for her patients.
However as a practice, I found it very weird how they kept says Dr. Aziz’s name. He must be her partner - but even when calling to confirm my appointment that I made w Dr. C they phrased it as “to confirm your appointment with Dr. Michael Asia and associates” which was very confusing because I picked Dr. C based on good reviews. Also as a medical doctor with years of experience she deserves her name being said. The office also has a lot of cosmetic offerings like weight loss plans and things I am not interested in.
Despite what must be Dr. Aziz’s large ego or insecurity that needs his name said every 5 seconds, I will be returning because Dr. Chaglassian was a great doctor.

Gentle and answered all my questions
January 4, 2019Erica D.Verified patient
I attended for an annual physical- usually just questions, blood pressure, and blood work. She was a very friendly and efficient physician, quickly spoke through my medical history and took my blood pressure. I let her know prior to the blood work that I have difficult veins and a tendency to faint at the sight of blood/needles (bad combination). She was very reassuring but once the needle was out, all bets were off. She poked around for a while (with my veins, that's expected) but once it was "dripping" into the tube she had me hold the needle in my own arm. When I began to faint I had to continue holding the needle as I sat back. I am not sure if she was short staffed with the holiday, but I would recommend not having a fainthearted patient hold her own needle.

Another great experience like I am always with her: very knowledgeable, integrity, accurate diagnosis. The only PCP I would recommend.

Mary Chaglassian was very quick and professional. She seemed to care about me, as a patient. She was so fast, it was almost too quick.

Had a good correspondence over the phone with the receptionist who booked me, and the doctor and nurse were cordial and professional. Appointment went by quickly with little waiting time.
Only issues I had with the office were with a rather curt and rude front desk assistant, as well as the posters on the wall of various celebrities who were deemed too overweight (with the food network ironically playing on the TV).
