On today, April 28, 2026, I took my mother to the Neurology Group to obtain a copy of her medical records and specifically an MRA and MRI conducted at the behest of a doctor with the Neurology Group. Office personnel, Brittany, refused to provide this information, indicating that the information would be shared with my mother in June 2026. This is a violation of HIPAA, the conduct required for doctors pursuant to the CA Medical Board and her rights as a patient. Despite explaining to Brittany that this information was needed so that it could be shared with my mother's other treating doctors, Brittany refused. The medical doctors with this group (Faisal, Zhang, others) seem to be billing the insurance company without providing patients with necessary test results so that patients can advocate for themselves and their medical needs. Waiting until June to receive test results done in April could be too late and could result in an unnecessary delay in medical treatment. I am going to have to file a complaint with the CA medical board against the medical group and I'd advise any person considering using this group's doctors for medical care to think twice because they are effectively delaying my mother learning about an acute diagnosis (acute frequent strokes) which could result in a negative outcome. I will be finding another neurologist for my mother ASAP. STAY FAR AWAY FROM Dr. Bhupat Desai (agent for service of process), Dr. Qazi Faisal (president of the Neurology Group), and the Neurology Group's doctors. read more

This is the most miserable office I have even been referred to. STAY FAR, FAR AWAY. I was referred over a month ago? Called in and asked to schedule my appointment, they said they needed my referral. Sent the referral and called again only to get asked for an approval which they also should have already had. Called my GP and had them send in the approval to call back again and be hung up on, call again and am told they're experiencing technical issues and to call back 30 minutes later. Called again 45 minutes later and was HUNG UP ON AGAIN. They messaged me and told me to call them again there was an issue with the line and made me wait on hold for another 10 minutes. I have now in the last 72 hours spent 3+ hours on hold and gotten no where. Would give 0 stars if I could. read more

The doctor dismissed my problems 5 minutes into the first visit and was more focused on an ADHD diagnosis. When I said I wasn't interested in medication she fired me and said to see my PCP for my headaches and aphasia. Now I'm getting calls every month or two trying to sell me some fancy new brain health service that isn't covered by my insurance under the guise of "seeing how I am doing". Super classy. One of the worst practices I've been to. read more

I'm deeply concerned about my IPA referrals to an extremely disorganized and dysfunctional medical office. Today, The Neurology Group threatened to cancel my upcoming appointment because they couldn't locate my authorization--despite it being faxed eight days ago. After multiple conversations, I was told I had until 4 PM to provide it, or my much-needed appointment would be canceled. Under pressure, I left work to resolve the issue, only to receive a call an hour later saying they had found the authorization. This mistake cost me time, money, and unnecessary stress. A medical office that misplaces authorizations and threatens to cancel appointments due to their own errors is completely mismanaged. I will never use or recommend this office--RUN! read more

The Neurology Group - I HAVE, AND WILL DIE FROM, AND BECAUSE THE NEUROLOGY GROUP NEVER FOLLOWED UP ON ANY OF THE TEST THAT I HAD OR DIAGNOSED MY PROBLEMS. - Neurologist Near Me - Pomona, California

DO NOT WASTE YOUR TIME!If I could give 0 stars I would. Disorganized office. Called 2 weeks prior to make sure my cat scan was there for the doctor. 1 day before appt. get a call from staff asking about cat scan. I reiterate that someone dropped the ball. they said they would get the CT. Phone call from Dr. Puja Mathur, MD. She is exasperated, sighs throughout whole phone call. Was irritated and combative because her office did not provide her with the CTscan. Asked me to go through everything I do. She asks me again for the same info. Sighs again is irritated and pretty much upset I took her time. Kept interrupting me but wouldn't listen when I explained. Kept arguing with me as far as why I would even think I could be dying without even looking at any records. Finally saw this was a wash and told her I can see why your practice and you get 1 stars. She was unprofessional, un supportive and combative. DO NOT WASTE YOUR TIME. Now I need another referral that will take time, not to mention the time to get into a doctor to see if I am dying. Thanks alot. read more

The receptionist guy that takes the phone calls should be fired immediately he does not speak proper English he makes you spell the first and last name not once not twice but three times he said he's bad at spelling names, he's even bad at getting your address very slow keeps you on hold for a long time. Ask you to wait one minute on hold but then puts you on hold for another additional 10 to 15 to 20 minutes. I have to redirect one of my children to a different neurologist. I'm gonna have to also today redirect my child's Neurologist to a different one again because insurance keeps sending me there. For two different children. This place is horrible. The guy needs to lose his job. He didn't put me in through the manager. He refused to even let me talk with her and saying that she's busy which sounds like a lie he didn't put me on an additional five minute hold only to tell me that the manager is not available and he's gonna send me through her voicemail then put me on another hold for that and then transferred me to a voicemail that was full. The mailbox was full so he knew exactly what he was doing Alice or Elsa whatever your name is you need to be fired read more

The drs don't listen to you and the staff is incompetent. I have tried to find another neurologist but there isn't one within my med group.

It's dr.won Jo is the dr. That couldn't help me and that told me that everything is fine

Update from last week. I left the neurology group today and canceled all to future appointments. When a neurologist explains a medication to you that she feels will be right for you but doesn't fill it...that's a problem. Her assistant told me that the doctor wanted my GP to fill it rather than the neurologist. This is an extremely bad practice. It appears to me that this doctor is afraid of litigation so why bring the medication up to begin with? To make matters worse: in addition to my several phone calls, my doctor answered none of my online inquiries over a two week period. I've never been treated this way by a "professional practitioner" in my life. Avoid the neurology group. read more

Appointment time was a joke. I waited anywhere from 30 minutes to over 60 minutes for the doctor to come in the room. Lunchtime for the doctors and staff takes president over patients. I was being seen for possible neuropathy. The first appointment for the EMG went smoothly. The EMG tech was awesome. The second appointment was a nightmare. The EMG tech was always on time, professional, and personable. I waited for over an hour for the doctor to return to finish EMG. The office is showing limited cleaning and upkeep. My follow up appointment was with the nurse practitioner via a telehealth appointment. I'm still uncertain if I do have neuropathy after that appointment. The follow up was being referred to four or five other health professionals. All in all I can say seeing this neurology office was a great disappointment. read more

WOW WOW WOW I've waited 2 months for this appointment for my daughter. After 2 years of therapy, our entire care team have agreed to my daughter definitely being in need of a neurological examination. I am not even kidding you, we were in the exam room with Dr. James Collen for no more than a 10 minutes. Most of that time was spent asking basic questions; allergies, medical conditions, family history, etc., the other half of the time was him telling us that the main reason my child is the way that she is, is due to screen time, and to cut it out cold turkey and completely 100% and he would see us again in March..... There was no consideration for A) all the reports we have not only from the referring pediatrician, but also all the therapists and regional center on our care team B) evaluate the patient herself as far as Reflexes, Motor Skills, Balance, or simply just watching her how she walks ..... I have to be honest, I read the reviews and I did call my pediatrician to refer me elsewhere before this appointment, but due to the amount of time we waited for this appointment we agreed as a team to give this doctor/office a chance, AND BOY DO I REGRET IT. The moment I walked in, I said "Good morning" loud enough for the entire front staff to hear/acknowledge. They all looked like they hate their job, didn't respond and give you zero sense of comfort with trusting them with yourself let alone your child. Coming from the medical field myself, and more specifically, working in a pediatric specialty, this office and doctor are a complete RED FLAG. read more

Very, very rude and sour office staff. Never even saw the doctor because after dealing with front office didn't even want to see the doctor. read more

Brain health is too important to trust with this doctor- she let's you wait over 2 hours to be seen and then does not even listen to what you share. She then writes in her notes the exact opposite of what you tell her- this is concerning to say the least. And...lots of luck trying to get her to correct her record. read more

Everyone was extremely nice and helpful. The Dr took his time to explain everything and answer all of my questions and concerns. I even received a call back from the office to discuss my medication and schedule my appointment. read more

Do not waste your time. I can't understand how they stay in business. It takes at least 5 months to get an appointment and at the last minute they will cancel it with no current availability for a reschedule. And the new call center you cannot understand the person on the other end of the phone. read more

Their performance should be measured on a scale of incompetence to parody! I could write a tomb as to their embarrassing performance but I will let other patient's reviews speak for me. It has got to be a sign that so many people will take time out of their day to share their experience, it's surprising that more satisfied patients aren't moved enough share how they feel. Good luck if you get referred there (or the Upland office). Don't be afraid to be an advocate for yourself, it is more than likely that you are more knowledgeable than the staff (I had an MA/LVN that didn't know how to use a scale!?! A standard scale?!? She said "they didn't train me in that kind."). read more

If I can give this place a zero star i would. Their worker was really unprofessional and rude. They dont have the patience and the passion to work with the patient. Absolutely avoid this place. read more

There is a person by the name of Brenda that is the lead in memorytesting there that is very rude and will cut you off when speaking to someone there. I was in today to get a test done for my elderlymother and since the minute I walked in and speaking with the clerk she stepped in not knowing what was going on and tell me how things where going to get done. She would not let me finish asking a question and wanted to make sure that there is no one other than her that I could talk to. I was told she is a lead. Not a manager, just a lead. When reaching the main line, I was told I would get a call back from a partner there. But it's 11pm and never received a call. This is not a good place to go to. If she represent this group, I will have nothing to do with them. Appointments also take forever to get. They probably over work there employee, that's probably why Brenda acted the way she did. But NO EXCUSE for that behavior. read more

I had an appointment with Dr. Farsani on November 8th, 2023 a representative called me to cancel it because she said that the doctor Farsani resigned from the clinic and that they would call me to give me another date for my appointment. I'm still waiting for the appointment, I've called more than 8 times and left a message with Nancy, but she is a lazy and irresponsible person who doesn't return calls. I sent a message to the email and they didn't respond to me either. I sending text messages and the unique answer was: "I apologize for trying to help you" And I responded: Why doesn't anyone return the calls? I need to make an appointment to see the neurologist Steve Tiu, he is the doctor who has shown interest in my problem. But I think that the customer service staff is not interested in answering the calls, if that is the case, tell me and I will look for another clinic that is interested in having clients. But I no longer received any response. I'm going to have to change clinics because I see that they are not interested in seeing patients. Dr. Farsani, like Dr. Steve Tiu, are good professionals, the problem is with the receptionist named Nancy, she is a jerk who does not answer calls and you are left without medical attention. They should fire her and hire a person who likes to work. read more

Horrible front office, also doctors don't care they just prescribe medication and don't want to find the root of the problem. If you start to question anything they are quick to refer you out. Seems like the doctors don't take the time to fully assess us patients but they bill like they did. I will file complaints to the state boards to look into this practice and offices read more

If I could give this place a zero I would. The doctors have no care for their patients. I've had nerve pain for almost a year they have done nothing about it. Ran some blood test said they found nothing abnormal, they don't want to run any other test. I've been a patient here for almost a year and I've only seen the doctor ONCE. They never answer their phone so goodluck trying to get any of your questions answered or even getting an appointment. I finally had an appointment in person tomorrow at 9am my husband had to take the day off so he can watch our kids. I had missed call from them today at 5pm once they are closed and I heard the voicemail they are canceling my app and I couldn't even call back to ask why cause they are closed. This place is HORRIBLE. read more

This clinic is always messing up my prescriptions, my medication and always rescheduling my appointment or switching them to FaceTime or zoom and I'm tired of this place not taking care of their customers and using them as numbers only. If possible, do not come here trust me you don't want to. You're welcome. read more

They are so disorganized. Had an appointment at 8am for a nerve test. They changed my appointment to 1pm without contacting me about the time change. They said if the person who had the 8:30 am nerve test today did not show up I would be taking in then. At 8:45am I ask about them taking me in and they had to call the technician who performs the nerve tests. Then told the Technician wlis driving in can see me @ 9:45am. They lied! Very dysfunctional office read more

TLDR: Incompetent staff, lacking property training on internal procedures and basic due diligence. Called in with referral and spoke with Norma to schedule an appointment. Norma requested that I send in my referral documents via text message per their procedures. I sent the requested documents from an iPhone. Norma replies to my message and photo with "Good morning my name is Norma, I will be calling by the end of the day. Thank you". (Norma never looked at the information sent to her,since according to her, the image never when through)... She proceeds to call back 4hrs later only to say that there was an error, and that they no longer accept my insurance provider. Now that isn't why there is a 1 star rating. Carries change all the time, these things happen. The issue is the time between my initial call/message and when Norma decided to call back and inform me of the situation. If Norma would have done her basic due diligence from the 1st call at 10:50am and looked up my information over the phone when I provided referral number, she would have noticed that they no longer work with my provider and I could have then started the process of obtaining a referral for a different neurologist within my network. Spoke with a supervisor Irene who was no help either, just an attitude. Hands down worst customer service I've had from a medical office. My insurance ended up getting an exception, but declined chose and office who actually looked up my referral on the the 1st phone call. I'll take a drive to Pasadena any day then go through this nightmare. God only knows how there care is face to face. read more

If I could give -5 stars I would. First of all when making an appointment, you will not speak to anyone in the office. You will be speaking to a phone service. That phone service will make the appointment. If you have any specific questions, or any further details to give, or get, there is no way to contact the office directly. I had questions concerning my husband's appointment, and I had to physically go to the office in order to speak with the staff about my concerns. My husband never saw the neurologist in person. Had an initial phone consultation with Dr. Quasi and he did not know anything about my husband's medical history. This was AFTER we were referred by our primary care physician, and filled out a lengthy questionnaire as to why we were looking for a neurological consultation. The doctor thought my husband was coming to him for migraines, and proceeded to prescribe medication for the nonexistent migraines. My husband told him that he does not suffer from migraines, and that is not why we were seeking a consultation with him. We then scheduled an in person consultation. After my husband's in person testing/consultation at the office we still did not see the doctor. We saw the nurse practitioner, which is fine, because I would assume the doctor does not conduct the testing himself. My husband was then referred for an MRI. When the results came back, I would have expected us to have an in person, face-to-face consultation with the doctor. We did not. We had a consultation with him over the phone and that was it. The doctor said the MRI results were negative and there was nothing to be done for my husband and that was it. I had questions for Dr. Quasi and he was dismissive and reiterated that the MRI results were negative and there was nothing "wrong" with my husband. Not surprisingly the office staff is equally rude and dismissive. They make you feel as though you are bothering them or keeping from something important. The eye rolling and heavy sighing was more than I could tolerate. Would not recommend anyone in this neurology group after this horrible experience with this doctor and office staff. The only good thing I can say about this office is that it was clean, and the nurse practitioner was extremely patient, and listened to the concerns my husband and I had during the testing. read more

When an office can not schedule a test from November until today, personally spent over two hours on music on hold to try to confirm appointment. Then when we show up are told that the test was moved to an office 12 miles away. The claim was that they left a message Friday. We have to call BS on that as there was no message Friday from anyone. Small wonder that this group has online ratings across the board on all mediums of 2 or less. read more

This is the worst care, if you want to call it that! Over booked, understaffed. Hard to call in and speak to someone. And good luck getting an appointment any time soon in the near future. I suffer with severe migraines and they don't have any availability to be seen in 6 months! They asked if I wanted a telephone appointment!!! And when you are seen they just want to prescribe several pills instead of finding out what the problem could be! Worst medical office ever! read more

Not sure how this place is in business still. They don't respond to emails or calls. I have been calling for 2 days now straight and have not been able to get through anyone on the phones. From my experience being in the office, they have quite a lot of staff sitting and standing around. I am not sure why they cant answer the phone or do their job right. My daughter has been waiting 4 days for her prescription to be called in to the pharmacy. I will be reaching out to my insurance to change providers. Honestly, this place is a real joke. read more

DO NOT USE The Neurology Group. Just try calling to change an appointment, get a prescription or for any reason you will be on hold forerver. We were just on hold for 58 minutes before, what seems to be an answering service picking up. Beleive me even then you won't be done yet. DO NOT USE The Neurology Group. DO NOT USE The Neurology Group. DO NOT USE The Neurology Group. DO NOT USE The Neurology Group. I did see a very few five stars reviews, they must be relatives. Look at the abundant one star reviews. That has got to tell you something. You would be better off going to a veterinarian. read more

My son had his first seizure years ago. We were referred with multiple neurologist within the area and had no answers. We were then scheduled with The Neurology Group and saw Dr Collen. The attentive care and acknowledgement to our concerns made such a difficult situation more comforting. He explained everything in an understandable way. Not only addressing my concerns but my sons too. Dr Collen has gone above and beyond and has helped us in this journey. We are forever thankful. There are a few doctors like him where they make you feel like you matter. Best neurologist. We wouldn't go anywhere else. read more

Last straw. I'm finally switching to a different doctor and different office, hopefully one that cares more about their patients. This office is next level of incompetence. Every time I talk to anyone associated with this office, I'm left in a bad mood. Believe all the horrible reviews for this place. It's not a one-off fluke. People who work in this office are really that bad! If you care anything about your health, do not come here! read more

Absolutely blown away by how bad my experience was and I wish I had seen these reviews before going. If you have any choice at all go elsewhere. - Front Desk Staff: Appallingly rude. As Simple as that. The reviews consistently orient around that fact and my experience was par for the course. - Actual Care: Literal no shows for appointments. Twice. Had to threaten legal action for an actual feedback session to happen by a needed date that when it did happen felt like a series of minimal effort moments. - Pros: They do have some very nice people working in the back office but the ball dropping by the front desk staff is probably why you'll end up speaking with them. read more

Absolutely terrible service and almost impossible to get an appointment scheduled and even more executed. If I could leave zero stars that would even be too much. What a bunch of unmotivated people there, and most doctors are by far not taking anything serious and follow up on anything. What a joke. Tried for over a year to get my issues sorted. And mostly the appointments got cancelled by scheduling or double booked. Doctors never follow up or follow through. Incompetent and should not be in business. Definitely a case for the BBB. read more

We have ZERO complaints about the staff and doctors at The Neurology Group. Our high school athletic son has been seen 3 times for a concussion and first time seizure. We were very anxious regarding the medical issues our son experienced. The staff and doctors at this group made the whole experience easier to deal with and made us feel confident that this matter could be treated. Dr. Collem has been outstanding with our son. He not only speaks directly to him but to us as well. He is patient, thorough in his explanations, provides educational materials regarding the medical issue, speaks plainly, doesn't talk down to us, and conveys genuine care and concern. His medical assistant Vanessa went above and beyond to make sure our authorization was received and tracked it down for us. At the front desk, Cameron was friendly, helpful and made it easy to schedule this appointment and our follow-up appointment. We highly recommend this neurological group! read more

My mother came here by referral from Pomona Valley Hospital. After this office constantly changing her appointments, she finally went in today to her appointment. The receptionist there was extremely rude and disrespectful to her simply because my mother chose to speak to her in Spanish. My mother tells her you know what if you're going to have that type of attitude and can't help me, find someone that will. They had her waiting and all of a sudden say they don't take her insurance? I don't understand how this place is even open with SO many bad reviews? How are these idiots behind the desk not fired? I've worked as a receptionist and I've NEVER treated someone so disrespectful or have been so stupid and unfair to patients no matter how rude they were to me! And the saddest part is there isn't even a number to call to complain about these people. read more

Horrible office. Zero stars if I could. I was a new patient. I saw Dr Farsani He approved a refill for a med and said he wanted to start with an mri. Checking out, I was told they would call in the script and submit authorization for the mri with my insurance. It took 2 weeks and my pharmacist making several calls to get the prescription order. Its been 3 mos and still waiting for them to submit an authorization for an MRI. I called in so many times to get that referral. Each time my call was transferred to the person who "handles" referrals WHO NEVER ONCE ANSWERED THE PHONE. I left so many messages...I give up! I'm looking for a new neurologist now. read more
