The office is a rip-off. They charge you a dollar for a mask! Make sure you bring your own where you can buy 50 of them for only $2.50. The front desk people are so unprofessional!

Great doctor - horrible staff I wish I could send an e-mail to the doctor rather than writing this public review about his staff, but there is no e-mail address listed on the website, and of course the staff in GH office are very irresponsible to help over the phone. We visited the doctor in Canyon Country office on November 30, my 9 yrs old quickly connected with the doctor, and overall, it was a great experience, and we found the doctor to be very knowledgeable and helpful. Our daughter was prescribed an inhaler to use before her physical activities. The following day I pick up a form from her school to be completed and signed by the doctor, so she can self-administer the inhaler at school. The Granada Hills office told me the doctor was not in GH that day, and in the next couple of days they will call me to pick up the completed form. 20 days have passed, and they have not called me yet, I have been calling the office sometimes a few times a day; I am on hold for 12-15 minutes each time, and every time they say the person in charge will be calling me back, but nobody has called me yet. This is very disappointing to see a wonderful doctor has such unprofessional staff. I am not sure if the doctor is aware of his staff’s attitude and their lack of work ethics. This office needs better management, and an e-mail address (listed on their website) directly to the doctor or somebody trustworthy to be contacted in situations like mine.

I would give this place 5 stars but the White, Hispanic looking receptionist is so rude and cocky and does not show any concern for patients. She is always at the front desk and you have no choice to ask her questions and she gives a mean look all the time. I tell her both offices are out of drinking water and her uncaring response is "Oh, okay"
