The doctors here are excellent, but the overall service has become unacceptable. It's nearly impossible to reach anyone directly by phone now , they've eliminated the direct line and force you through a third-party system that's completely ineffective. I've spent over 40 minutes just trying to get through, and it's a waste of time. This office has gone downhill. Scheduling an appointment with a primary care doctor takes two months or more, and while you can see a nurse practitioner sooner, they don't seem to communicate or relay notes back to your primary which defeats the purpose. The practice clearly overbooks its doctors and expects patients to tolerate it. This level of disorganization and inaccessibility is extremely disappointing. read more

The wait times to get an appointment are unreasonable. When I tried to schedule with the first available doctor, the appointment was set for five months out. Additionally, I underwent a bone density test but have yet to receive the results despite multiple calls and messages to both my doctor and the radiology department. It's been three months, and I still haven't gotten any information. Waiting five months for an appointment and enduring delays in test results are simply not acceptable. read more

Horrible horrible service. Do not choose this clinic. Whenever I come in for appointments all they do is load me up one new meds. They never take the time to truly try to understand my condition nor do they desire a follow up. Appointments are in and out 5-7 min long with a PA. I always call for status of my referrals. I understand the process takes time but they never call me for a follow up call like they say. I always have to call for an update. When I do call they sound irritated or annoyed about my inquiries. Will definitely be transferring to a new PCM soon. Don't waste your time, find somewhere else. read more

Terrible customer service sense the merge with Optum - it's gotten so bad most doctors are living and patients are complaining in the waiting area Mom is 83 she has been going to Magan for 22 yrs, I think shortly we are leaving Magan and 6 of other family members no customer service they hold on phone is long and no follow- up with the care. I have been on hold for 2 hours and left 2 messages for Optometry Dep- no calls back that is crazy. read more

Friendly staff but HIDDEN CHARGES AND LOW EFFICIENCY. Long story short, I scheduled preventative care here that is covered by the insurance. The Magan Medical Clinic (currently Optum) still charges me $100+ in a bill. I called the Clinic regarding the bill, and they said they will investigate the issue and reply to me within 7 business days. However, after multiple calls from me to the clinic, they replied 2 MONTHS after with a reason: "Going over the lab result (which I did not ask for at all) will be charged for $100+..." In the end, still paid the amount, or else they will put the bill into a debt collector. Will probably never go there again with such nasty experiences... read more

Dr. Argudo at Diamond Bar office is great as well as the whole staff at Diamond Bar. Highly recommend!

I usually have no trouble with this clinic. I went in for a physical and the doctor had me do a PAPSMEAR even though i told her it wasn't a good time since I was sexually active. Ended up getting my results and it had "abnormal squamous cells" and "metaplasia". These are terrifying results. I have to go get another PAPSMEAR but honestly the trauma of the results has me super angry at both the doctor and clinic. There were a lot of other things about this visit that bothered me but this really traumatized me. I'm still debating action again this clinic. Beware. read more

I won't bother giving any explanations about this medical facility because you will never be able to get an appointment here anyway. I've lived in Diamond Bar all of my 36 years and my insurance has always been linked to this location yet I have NEVER in the last 10 years been able to get an appointment here. You will ALWAYS be directed to the West Covina facility. So just don't even bother. Oh and yeah the front desk are some of the rudest people I've ever met. Shame too because when you're sick and don't feel good it would be nice to speak to someone with some compassion. read more

I have been here a couple of times and I really do not enjoy my visits. The staff is not rude but they are not overly friendly or welcoming. A girl who usually walks me in is actually very sweet and nice. Issues i have had with this office: I coud not turn in a document in to work on time because they would not return it to me. I had to call multiple times on different days and gave them almost 3 weeks to return it to me. They kept telling me they would and never did. When they finally called me back, it was too late and I could not get health related credit through my work. The doctor told me she would be sending my refills on prescription and never did. TWICE. They are disorganized. I've had two separate people follow up with me about the same things. Blood work has to be scheduled on the side, on your own, at a different time, not in the same office. It's actually in a crappier office than this one. read more

The doctor/PA never see you at your appointment time, even when you are the FIRST appointment of the day, which doesn't make any sense. They are always arriving late, strolling in like they don't care that you had to take off work to make an appointment and now even more time because of their blatant disrespect. The front desk people are not kind or welcoming. They often have major attitudes. As far as I know, receptionist are supposed to be the face of the office and are supposed to be kind and welcoming, pretty sure that's a given in a customer service. They don't even smile, wtf. They often mess up blood work orders. They say they send them, but don't. So when you go to the lab for your blow draw appointment, they break the news to you, so then again your left taking MORE time off of work using up your sick time for something that could have been easily avoided. You can never make appointments, even if you've been hospitalized and have been ordered to see your doctor for follow ups. I really wonder what type of patients actually get to see Dr. Lawson. Ok rant over. read more

I have been trying to go here for the past three years. This last time was the last. I come from HMO (Kaiser) and cannot believe that this place is worse. Here's an example, when you do want to see a doctor, you have to schedule an appointment that is far in advance (even if sick) or you can see any nurse practioner or PA, who is usually worse than you waiting the sickness out. Next, you get blood work or an xray done, and seriously, you wait for weeks and no one sends you a letter or calls you. I called about an xray done 4 weeks ago (several times), I finally got really pissed off and a doc came on phone to tell me results. Really?!!! And it's so bad that they keep saying "Oh you need to call Covina office...call Urgent Care in Covina...call Diamond Bar". Well, I won't be calling them anymore - rather go all the way to Irvine for way better care. read more

Terrible that I can never see my assigned physician when I am sick. Always takes a week to get an appointment. I hate going to urgent care, waiting two hours to see someone (different) every time. I could understand if I had low cost insurance but this is ridiculous. read more

If I could give NO STARS, I would. This clinic is absolutely terrible if you are ill. If you're healthy, you don't have much to worry about and you can chance going here. But trust me, the second you are actually in need of medical attention, you're not going to get it here. I have been so ill since this past summer. I've asked to see a specialist since June. I've yet to get my referral. I am supposed to take additional tests which apparently also need a special referral. I haven't gotten that either. At this point, I can only hope to God that what is wrong with me isn't a condition that could turn out to be life threatening. If that's the case, I have lost valuable time. Thank you so much Magan Medical Clinic. To anyone reading this, for your own good, look for another clinic and NEVER consider this place. They do not operate for their patients best interests. read more

I have been a patient of Dr. Yvonne Lawson for 23 years. She always takes the time to visit with you and ask how things are. You don't feel like she is in a rush to see the next patient. It's great running into your family doctor at local places, and it's even better that she remember you and ask specific questions. The only negative thing about Magan is the wait time in the lobby, but you can usually get caught up on your ABC soaps! read more

I am very disappointed with Magan's Dr. My primary Dr. send me for blood test 9/24/15. I left message to my primary Dr. to call me back on the results. And NO RESPONSE as of now 10/19/15. And as for their patient portal where they upload your test result. It did not display the normal range for each test, so you can at least you know whether your blood count is high/low/normal. Its just so useless. It did not has red flag for any adnormal result so you can truthly bug your Dr. for answer. Very disappointing. read more

Let me start off by saying I have been a patient for over 15 years at this place. I normally go to the Covina office and have enlisted my Husband 3 years ago to also become a patient as I was always pretty happy with the care I received. My husband goes to the Diamond bar location and sees a Dr. Hahn there. He is pretty healthy more then me so he just goes to get his yearly check up and his blood pressure pills. Every year it is the same thing the refills are automatically given and when the time comes that no refills will be given he sees the doctor for the current year and then gets them refilled for the year. These are not narcotics but blood pressure pills to stabilize his blood pressure of a man that is 50 and needs them to be healthy and not have a heart attack. Last week we had not gotten a text from our pharmacy stating the pills were ready to be picked up. So I called the pharmacy and advises that doc did not authorize refill so I figured it was time for him to see the doctor. I called the clinic and left a message reg this and a day later a LVN by the name of Crystal called my husband back stating that he needed to make an apt. Very well I called apt center to find out his doc is out on a medical leave so the soonest they had with another doctor was on 1/20/16. I took the apt and had them send a message that if he could get his refill for dec and jan since they cant see him until then. By Wednesday mind you I had not heard from the doctor or the nurse and he was down to one pill, so I called back to speak to Crystal an LVN that works with another doctor since his doctor was out who works in the Diamond Bar office. Not only was she rude did not listen to me would not let me speak over talked me took what was on my husbands chart since he had been a little flaky in the past not going to his appointments and judged him on it and said to me,"well your just going to have to wait there is nothing I can tell you". His doctor is out and the doctor I work with Dr. Lawson has not had time to review the message. I said to her 3 days later she has not had time, so I guess it isn't of importance to allow my husband refill of bp meds not go through because he has not been in to see his doctor ha? He is already on the books for January since its your earliest so your telling me to have him go without them? Her response well Its his fault for not coming in sooner. I immediately said to her who do you think you are talking to in that manner? Where is your customer service and where do you think you can talk to a patient in that way. She went on an on saying its too bad deal with it and so on. I had gotten her name at the beginning of the conversation but just to make sure I asked again who am I speaking too? What she did next I could not believe, she strait out hung up on me. I never used one profane word she would not let me talk its obvious she does not like her job and Magan allowing this kind of behavior makes me understand now why most of the doctors have left and the caring compassionate LVNs and are no longer there. I immediately called patient relations and advised I want this escalated to the administrator so he can see what type of people he allows to get employed and how they are representing his clinic. Listen I know we are all overworked and underpaid I live it daily i have worked in the medical field for over 30 years and never is there a time to be judgmental or treat another human being as she did. You better believe I am taking this all the way to the administrator and if he does nothing about this I will get this to his boss as well. Everyone has a boss and this nurse needs to be fired for the way she treated me and my husband. I wont let one non caring person take me from where I go see a doctor. Or allow a person like this be given the responsibility to give this kind of mistreatment to other read more
