Dr. Riahi is knowledgeable, courteous, polite and always very caring towards his patients. I’ve been seeing him for over a year and have referred him to many friends and family. Everyone who I’ve referred has been so happy with their visits.

He’s an amazing doctor, I really appreciate how he calmed me while I was a little tensed! He explained everything to me and what he was doing to me.
I’ll say I didn’t like how the lady with the hijab treated me, very unprofessional! I spoke with a front desk person (lady) a day before my appointment asked her all necessary information and when I went up there the lady with the hijab treated me like I’m lying or Illiterate which really broke my zeal with my experiences at the office!
Overall Dr. Ryan you’re amazing and know what you’re doing. Thank you

Dr. Riahi has been my doctor for the past two years and he is FANTASTIC!
I just moved to California 6 months ago and while traveling home for the Holidays, I made sure to make an appointment for a follow-up to get my refills.
He is very professional, listens very carefully and his easy to follow regiment has slowed down my skin's aging process tremendously.
I will be back year after year as he is the only doctor I trust!
Thanks Dr. Riahi!!!!!
