We love Dr. Daghigh and the staff! Dr. Daghigh has been very helpful with my son who's primary issue is asthma. He listens to all my concerns and comes up with a good plan that works for us. He is also great with my 5 year old son too making him feel comfortable.

Had to wait a month just to get a "tele-appointment". Had to scan and sign a bunch of documents and send them back to them or my appointment was automatically cancelled. All their website has is phone numbers. Why do you not have an email address listed on your website if I have to email you things. Appointment is on monday at 9am when they open. even though I know I need to send them paperwork on the weekend I can't send them anything because their website is useless. Went to another allergist in the area that saw me in person, did allergy tests, and went over the results with me all in one appointment
