Update! This place is still a SCAM lol you will not receive a call back. Your provider will ghost you. You will not be able to even obtain your medical records from them.

Let me start by saying that Dr. Cheng is an amazing caregiver, and in reading some of the reviews, I believe the other doctors here are as well.
HOWEVER. Scheduling an appointment is a nightmare. The call center seems to have no idea who they're answering calls for or how their phone systems work. Multiple times I have called and been placed on hold only to be disconnected or the call was not even answered. Now, when I do speak to a human, I'm told the office manager needs to approve scheduling me, due to some sort of flag on my account. I'm almost completely certain this person does not exist

Amazing and attentive doctor. Takes the time to really listen and is so caring and nice. He really helped me feel better. And despite having a completely booked schedule, Dr Suba took the time to personally call and see my little brother who was in a bad state. He is hands down one of the best and most dedicated doctors I've seen in Vegas. I highly recommend him! Thank you Dr. Suba you are a life saver, from Catherine.

I wish I looked at these reviews before making an appointment here. I waited 6 weeks for my first appointment. Called a few days prior as well as the day before my appointment to confirm information. Each time I called, I would be in the middle of speaking and they would just randomly place me on hold or transfer me to a voicemail mid sentence. I knew then it probably wasn’t going to go well, but had some hope and I had been waiting so long for the appointment. It was my appointment time and I waited for the link to come. 10 minutes with no link I called the office. They said my appointment would

Lol I predicted this clinic would be incompetent so I actually scheduled a visit with a different clinic. I didn't need to go here anymore but I was curious how it would turn out. Sure enough, the day before my appointment they had to cancel it but it's all good. I'm just playing with my food

Here's message I sent to management after Trina Singleterry failed me. Mined you they never responded!!

Is there a reason why management has not called me? I came to your practice for help with my severe ADHD. I was laughed at and treated terribly by Trina. Her assistant was great. She even confirmed Trina had all she needed to send in my updated prescription. Then after laughing at me, Trina never contacted me again. I'm going in my third week without my meds and it's turned my life upside down. After finally being diagnosed properly and being on the medicine for about 5 months

Only giving one Star because I have to at least give one in order to write a review. Worst psychiatry office I've ever booked an appointment with. Spent the last hour just trying to get logged onto the patient portal in order to get a link sent to my email in my phone for the telehealth appointment. Called the office four times was put on hold several times and then was told to call them back in 15 minutes. I never did get to speak to the psychiatrist because they said he was running behind.My appointment was then canceled without my request. When I called back to rebook my appointment they

The medical staff is the worst. They have the worst attitudes and it takes over a week to get prescription refills since they never pick up the phone or call back after leaving multiple messages. If they ever pick up the phone, they’re so rude and make you feel like an inconvenience. Find a different place.

Never had an issue my psychiatrist is always easy to reach if I’m having issues with refills or scheduling. Dr.Fallia is really good at his job and recommends the best treatment plan. My mental health issues has been managed and I feel overall my psych issues are maintained. I never encountered an issue thus far with scheduling or speaking to someone when I have issues.

Everytime I have to deal with someone other than my psychiatrist... I feel the need to remove another star or two. Condescending, rude and have no compassion for the people "THEY HELP". I'm constantly being lectured about not getting angry at their ineptitude. Whether scheduling me for the wrong times, sending my prescription to the wrong pharmacy, or not following thru/ up with promises; my recommendation is to avoid this facility at all costs. If your insurance won't cover another group... try and get different insurance. They now have it that they don't even answer my

I could never get Dr Castillo’s staff to give him urgent messages. When you put someone on a med and they call 8 times and tell you it isn’t working and causing issues you need to have a staff that will get you to respond in a timely manner. So ridiculous.

Scheduled a virtual visit for my son . I was told he would be sent a zoom link right before meeting . Day of appointment, we didn't get a link so I went in line to verify I had date / right. We noticed they changed the appoint (without notifying us) for a month later . Next appointment time , again we are waiting for a zoom link . I also called (as directed via text ) to call an pay out co-pay. Left a message that morning of the appointment. Time of appointment comes and goes , no zoom link , and still no call back for co-pay. I call again , answering services takes my info and says they will

My husband recently had issues with his meds that were our fault. My son threw away the pharmacy bag and there went his meds. Dr was awesome totally believed my husband because he rarely even fills on time because he doesn’t abuse his meds and sometimes forgets to take them. Pharmacy was being a pain. So we called his MA to call the pharmacy again etc. she literally told us no, her hands are tied there’s nothing she can do or will do…ummm it’s Friday he’ll have a 3 day lapse in medication. After me rigorously complaining and upset with the office the manager called back and sent it to

Before I start with why I have given this place a 1 star review I want to say that Dr. Castillo is a very kind dr who will listen. Other than a few drs who do care about their patients and treat them like real people this is probably the worst place you could go for your mental health.
This office cancels your appointments without notifying you. Your appointments (if they even show up) are HOURS late from the time that was scheduled. When working with people who are in need of mental health, who have mental health conditions, it is EXTREMELY anxiety ridden and paranoia inducing to be waiting on

I was referred to the office by a friend of mine to this office for John.
I had a lot of apprehension because the status of my son's and my situations were a bit difficult. I can say this was honestly one of the biggest blessings we have found in NV. He has been able to identify and treat problems that were previously misdiagnosed and really helped with our quality of life.
He is so amazing with my family and I can't overstate enough how great he is.
I can honestly say he is literally the only person I fully trust with my family.
He gets the five star rating.

I am beyond disgusted with this facility. They lie more than they understand the definition of the truth. They have scheduled my son a total of 5 times and then have never sent meeting links yet Bill my insurance for a no call no show but when I call and speak to their phone staff they blame it on the provider, Jon Failla. They say he was running late, or he left early or he couldn't see my son. Whether that is true or not I do not know but how Absolutely unprofessional!! My son (14 years old) has been out of medication for months and now has been hospitalized yet they could care less for anyone

Jon is the absolute best. He cares so much about his patients . From working with my schedule (so I can have an appointment with him specifically) to clearing up issues at the pharmacy so that I can get my meds on time, Jon has always gone above and beyond. He makes me feel like an actual person and not just another client. he even remembers details we talk about without having to look at notes. I have never had any health care provider be so invested in my well being. It's nice to see that there are still providers out there who don't just see us as revenue but as actual people. I don

John is the best for obtaining mental wellness. I shopped around Las Vegas and could not find a fit for my needs. He is the best therapist and I highly recommend him. I like the telehealth since it prevents me from driving in rush hour traffic. I hope they will always keep this service. Sometimes you have to understand that mental health providers are not a fast food service and people have real issues that need to be addressed. If you keep this in mind, it makes the late appointments understandable.

I have been going here for over two years-Trina Singleberry did not show up for one of our appointments via telehealth and will now not return calls or emails. My prescription has been denied and when you try to call you just get a never ending cycle of voicemails where no one ever calls you back. This place is a joke and a scam avoid at all cost.

Alliance is the worst. As I type this review, I am currently on hold - this is my third phone call to them in a week as I try to get a refill on a prescription I take for insomnia. I first called about it 6 days ago and was told (twice) "we'll leave a message for your provider"...still no answer from him, much less a refill. I cannot wait to find a new therapist and I can't warn you enough about this place. Worst excuse for health care I've seen, and in Nevada that's really saying something.

Another recent update. I was close to stable then had a manic incident. My doc decided to abandon my current med and start a new med, which interacted with two other meds I was taking (she didn't tell me or care, one was my heart) the new med made me crazy. I didn't know where I was who I was, forgot where I was going while I was driving! Dangerous, was swerving all over the road! When I told the doc, she didn't seem to care much, rushed me off the phone in two minutes or less, which was not her norm. She knows she did wrong. I'm moving on.

I was recommended to alliance mental health through my insurance. The staff was kind and courteous. They were able to schedule me around my work schedule. I see Dr Paul and there isn’t enough nice things I can say about him as a provider. He is professional. He listened to all my needs and took time to make sure I was getting the care I need. He’s been on time to all my appointments and found a medication regimen that really really works for me. I would recommend Dr Paul to everyone!!

After scheduling an appointment and confirming all information they returned calls saying they didn't have my information, needed me to upload but never sent the link to upload and then the time of my appointment I never received any kind of notification and called multiple times to speak with the scheduling dept to be told I was next in line and never to get a call. The staff was rude on the phone and unhelpful. And told me I was a no call no show and tried to reschedule me. Never make an appointment with their team and find a better provider.

The experience started out great, then it dovetailed into unprofessionalism and silly antics. I admit that times are difficult for providers during the pandemic, and coming up with solutions to still meet customer needs while being safe is critical as well. Yet when you claim to have a system set up in place, this system should work effectively. Alliance's doesn't, at least, not in my case.

GOOD

They were easy to get into, and when the pandemic subsided and they were entertaining office visits, they were just a quarter mile up the road from my home. Early on, the conversations with

I am SO happy to be working with Dr. Suba at Allaince. He was my former inpatient psychiatrist at Montevista hospital (before it died) and I actively sought him out when I moved to Vegas.

His compassionate, yet professional, approach to help me with my Bipolar Disorder's medication needs has made ALL the difference.

He is kind, patient, he listens, he is very interested in feedback about your medications and side effects- to help you get the bed help you need.

I am grateful for Dr. Suba seeing me. He is a wonderful human and a great psychiatrist. I am looking forward to working with him

I'm getting pretty frustrated with this place, as getting my prescription refilled is a struggle every single time it's due for renewal. They say you need to come in for an appointment before they're able to get something renewed, and then can't get you in for another 2-3 weeks. I try to reach out to the medical assistant, and never, ever hear back from them. That's the part that frustrates me the most. I'm now several days off my medication despite my leaving a voice mail last week to request a refill to hold me over to my next appointment, and I still haven&apos
