Friendly staff, very respectful and they do their job. I have had nothing other than five star service here at Medmark Hayward.
Been coming here for a long, long time Through my recovery I have had many counselors some better than others funny how things happen my husband transferred to Medmark from BAART in Oakland crazy we both ended up on… Rich’s case load { R.I.P. RICH another great counselor } so you know we both can’t have the same counselors so of course I got kicked to the curb. Best curb I got kicked to { so to speak. } which is currently Nicole Martinez, the best I’ve ever had , She definitely help me get to where I am now she goes above and beyond helped me in my life so much, I don’t even know what I’m gonna do when we goes our separate ways 😔..I wish I can take her with me. I wish I can give her 20 ⭐️’s but was only given an option of 5 ⭐️. ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾🙌🏾⭐️⭐️⭐️⭐️⭐️⭐️
Hi I'm Luis and I just wanna say my counselor is amazing her name is katt and I could not do it with out her.love u katt
Best n da Bay...
Not a good place. Legal drug dealers. They have financial help too they tell you to sell your stuff like if you're on dope still they say well you spend it on dope so why not spend it on this dope!!! Yes they want to… get you addicted to methadone to keep you on it for years.
I am a Client at this location. I have interacted with gilbert and talked with him about enough personal matters to know that he genuinely cares about his clients and attempts to do what he can to help out his fellow… human beings. I am grateful to be able to call him a counselor and a friend
Gilbert is a fantastic counselor and has helped me immensely. Any issue I have addressed with him he has been able to find a good solution. Since beginning my work with Gilbert my attendance has improved, I haven't… missed a single day. Thanks Gilbert for this and your future support..!
My name is Daniel and Gilbert Roos is my counselor and he has helped me tremendously in stopping my drug use of pills. My family is very happy as iam also with the treatment
My huband has been going here for almost a year now, Gilber Roos is his counselor, and has always been very informative. Gilbert has been a true blessing in our lives.
My counselor Gilbert works with me and goes out of his way to assist me in my maintenance treatment. I recommend him and Alan from experience these two guys are very attentive to your needs
It the mob
Medmark is a great Clinic with a good staff. Nicole is a great counselor that puts her clients needs first. It’s not just a paycheck to this company, many of the employees are sober addicts that have been through… sobriety. Sarina the director is also top notch. If your struggling with opiate addiction this is the clinic you want to choose. Medmark saved my life!!!
MedMark in Hayward is a methadone clinic and has been a life saver for not only myself but my family as well. The program is simple to enter and it's all about getting you stable and getting help. When you enter you're… assigned a counselor, and if you're serious about getting stable, you'll quickly become friends. They've lived what you've been thru, they understand and never judge and can help with a lot of stuff not just addiction related. For a small organization, they're amazing and serve HUNDREDS of patients. Thank you for everything you've done and are doing for us patients and to help stop the opioid crisis here in the Bay Area.
To Whom it May Concern, Legal drug dealers, no compassion for their clients. This place is horribly mismanaged and I have seen some of staff first hand make questionable decisions. I believe they are good people but… this is a medical building right, so I feel like there should be some level of professionalism.There was even a point where they decided to laugh / make jokes about the patients condition when they clearly needed help.. and as someone whos been through it its just not ok to make fun of someone when they are at the lowest point in their life. Let me get into some more details about my experience here: These people seem to have no interest in actually getting anyone off opiates, rather they just want to give you your fix daily and collect that easy 400$ a week from you or your insurance. I've seen the same common traits and complaints from people that have come there for a long time, and sure it does help kick street drugs but the addiction to methadone is no joke either, and it has some very serious new symptom's tied to it. I think the owner and the staff need to be held accountable for poor business and social practices and need to start treating the patients like actual medical patients, not like druggies. Don't push them around and make them jump through hoops just so they can get your drugs because you know they are desperate enough to do it. When I came in for intake I discovered the doctor only works one time a week (if that, sometimes the doctor doesn't show at all or shows up extremely late) They have their intakes come in first thing 5AM and agree to a 2-3 hour intake process , mine took 7 hours, from the time they opened until closing. Overall I think this place(MedMark Hayward ,maybe the other MedMark locations are better?) needs to be reviewed and held to a certain standard in order to ACTUALLY help patients, I would like to see people actually speak out on their experience here because in my short time coming I've seemed to question many of their practices and if this program is actually the solution, or simply just a way to get "dosed" and forget about the problem until the next day.. many of their long time patients have come for yearsssss.. maybe this was their choosing.. but when I signed up I was told you find a good level for you then slowly taper down so that you can get off opiates altogether in 3-6 month maintenance programs, but from what I can see they prefer to keep people coming back forever. And if you inquire about the 21 day detox program, it just so happens that medical doesn't cover that! so you'll be paying 280$ out of pocket if that's the route you want to go. I recommend talking to a doctor or clinic that offers Suboxone(buprenorphine) This clinic MedMark Hayward was supposed to offer suboxen some months ago I was told(It even says they offer it now on a poster in their lobby!), but since the doctor is hardly there / only works once a week he hasn't got around to it. for MONTHS... It just all seems so unprofessional to me, Another concern is privacy. They say they care about anonymity / privacy but they use a flawed number system as well as constantly say your real name and birthday out loud in order to confirm you. Another one that bugged me was writing my social on many pages in the intake process, and computer forms. And then having said pages left sitting around with private information just sitting there for anyone to see that just happens to walk by which includes other patients, not just medmark staff... I really hope this message gets in the right hands and some actions are taken to improve the clinic and the experience overall, Not just for the patients but everyone involved. this opioid crisis is serious and it should be treated as such, it shouldn't just be an seen as easy paycheck and it shouldn't just be a place for patients to forget about the problem that brought them there to begin with. because EVENTUALLY they will still have to face that problem, or stay taking methadone forever at the cost of 380$ a week.. ~A Former patient and a concerned citizen
Wonderful clinic. Went as a courtesy dose very friendly and professional.
Great clinic that really works with and cares about their clients
It's clean it's quiet and the people that work there don't take any crap from anybody they try to work with every individual that comes in there they go out of their way to help them
