This place is amazing. The staff is also amazing. Martha Diana Brittany Amy Nurse and Dr . They have been so helpful and accommodating. Never thought I could live without fet. And here I am living without having to use . I have a life where I implement God daily and grow my faith, have a support group to walk thru stuff with, and get to be a good mom and present in my daughters life. And this is just the beginning. They also have a taper down program for when I'll be ready to make that move. For now though, their program has been a life changer. Thanks Aegis. ❤️🦋

This is by far the best methadone clinic you can go to. They open early ( 5 am ) the nurses and girls at the front ( and Adrian ) are amazing kind people that get you in and out of the clinic super fast. I’ve curtesy dosed at multiple other clinics in and out of California and I never realized how good I had it at Ontario Aegis. Other clinics move so sloooowwwww and it takes forever to dose with only a few people in front of you. Good counselors also ( shout out to my girl Linda )

I CAME TO CALIFORNIA IN FEBRUARY OF 2017, AND I WENT TO AEGIS TREATMENT CENTER IN ONTARIO, AS SOON AS I ARRIVED IN CALIFORNIA. I LIVED IN PHILADELPHIA ALL MY LIFE, AND WAS AT A METHADONE CLINIC THERE FOR 11 YEAR'S . I CANNOT SAY ENOUGH ABOUT THE AEGIS TREATMENT CENTER IN ONTARIO AND THE PEOPLE THAT MAKE THIS CLINIC THE BEST TO ME. FROM THE FRONT DESK TO THE COUNSELORS, MANAGEMENT, NURSES AND DOCTOR'S, MAKE ME FEEL CARED ABOUT, IN EVERYWAY. I AM GOING ON MY 13TH YEAR OF SOBRIETY, AND I WOULDN'T BE WHERE I AM WITHOUT THE CLINICS. NO OTHER METHADONE CLINIC HAS COME CLOSE TO AEGIS IN MY 12 YEAR'S OF SOBRIETY, THEY ARE TRULY THERE FOR US TO BETTER OUR LIVES. THANKYOU AEGIS FOR MAKING ME A BETTER PERSON.

My experience with Aegis is outstanding! The people that I have met have talked about sobriety and the people at the front desk do an excellent job especially on days when the computers are down and they have to deal with all the frustrations from the people waiting to get dose but they do there job extremely well and care about the patients there. If not for Aegis I would be either in jail or dead? Aegis help save my life! I really mean that! THANK YOU AEGIS!!!! Also the best methadone clinic I been and the counselor help as well.

This clinic is great. Been here for going on 3 years. If you want to get clean they will help you do it. If you don’t want to get clean then what are you doing here? I started off at a high dose and am now almost off of it. The people who have left negative reviews on here are the problem people that the staff has to deal with. Be polite and courteous like a normal human being and you will never have an issue...

Wonderful staff, clean facility, affordable payment options including full coverage from IEHP insurance. They will work with you based on what you can afford. The hours are the best in the nation from 5am to 630pm no other clinic has been open that long in the history of methadone clinics. THIS PLACE WILL SAVE YOUR LIFE! Please if your struggling with opioid addiction they can help with several different options even if you are not sure about methadone. You can learn more or try other options like Suboxone. They offer counseling and many other support resources. I can't say enough wonderful things about the staff. They are amazing people and will get to know you well and treat you kindly and with respect. They are fun people too. They also cater to the needs of parents with small children by offering a playroom for them and watching over your kids while you dose or attend your counseling sessions. Thank you Aegis for everything you do for all of us, you guys saved my life and my loved ones lives. God bless you all. 😊

Aegis Hesperia is a clean clinic, the staff is friendly, and professional, but it can be difficult to see the doctor when you want to lower your dose.
