I can't say enough good things about Dr. Madyoon and his entire office. I've been a patient since a heart scare in 2024, and from that very first visit I felt like I was in the best hands. I have to start with the front desk because they truly set the tone. The fabulous Angie is an absolute gem. She's warm, organized, and completely on top of everything. The rest of the front desk staff are just as wonderful. Friendly, efficient, and always helpful. Appointments, follow-ups, insurance questions, it's all handled smoothly and with kindness. Dr. Madyoon is truly the best in the business. He's calm, incredibly knowledgeable, and very thorough. He takes the time to explain everything clearly and never makes you feel rushed or dismissed. When you're dealing with heart issues, that kind of steady, confident care means everything. His PAs are fantastic as well. Attentive, professional, and genuinely caring. I've always felt heard and taken seriously. The whole office runs beautifully while still feeling personal and compassionate. I'm so grateful to have found this team and would recommend them without hesitation. read more

I called to ask a simple question about supplements. I didn't request test results over the phone. If you can't even return my call for simple advice, you're not a caring doctor. read more

I was referred to Dr. Madyoon's office for a heart checkup. With what I imagine is Mayo Clinic level thoroughness his staff did a complete analysis, including echo and nuclear stress test. Excellent staff. They confirmed my appointments the day before too. Location was also convenient. read more

This is ridiculous. EVERY TIME I come here, my appointment is at minimum 30 minutes late with the average being more like 45 mins or an hour. I had to call 4 times & leave messages just to get an update on tests I had done. Finally 5 weeks after my tests, I get a callback to come & do more tests. They will charge you for being a no-show & wasting their time even though they have no qualms about wasting yours. Do not go to this doctor if you value your time. My last appointment was supposed to be at 3:30pm. The dr didn't show til 5pm! Unacceptable. He rushed through the little time he spent & clearly hadn't read up on my chart. This office is a mess. read more

I had a bad experience with Dr Madyoon and his staff The office staff rarely answers their phone and it takes so long to get important reports from them The dr has a very poor bedside manner. He rushes in spending 5 minutes and rushed out I honestly didn't know our meeting was over I had to ask his receptionist When he did my catheter exam he did not make eye contact and mocked me when I made a sound that indicated the needle going into my hand hurt Just choose someone else and save yourself the hardship read more

DO NOT GO HERE: I cannot believe how extremely rude the front desk woman was today for my appointment for my EKG. I had a 1130am EKG and did not get a phone call or confirmation prior. I also was provided the wrong address. I left extra early at 1030 am and am only a few miles away from home. I wanted to be there early to relax and do paper work. When I went the address was an empty lot so I drove all up and down and around looking for 740 S. San Vicente. Google kept telling me it was at the building of 640 next to the empty lot. So I parked and then I tried calling just before the appointment time to ask for help. That's when a women began to argue with me that I had the wrong address however how would I even be there unless I otherwise got the address from their office. Then she right away told me we have to reschedule. I was in shock. I asked why and she said because now you are late. It was 5 minutes from my 1130. I told her no one had called me to confirm. She said yes, she did and that I hung up on her. I told her, ohh that was you yesterday who wouldn't answer every time I said hello a number of times and sat waiting. I never got a call back or an email which a person would usually do if they knew a call was having issues. I could hear her breathing and background sounds but she would not reply. So here we are and now she is arguing with me about the wrong address and being 5 minutes late. 5 minutes I know I would have been sitting there in the lobby anyhow and filling papers or whatever. She could have taken me. Which pisses me off even more after reading the bad reviews of how they complain of a 30-45 minit wait in lobby. Then I remembered how this referral came from the Lesbian and Gay center and it immediately clicked. She was completely out of line and off from the very start from the moment she called to confirm with little effort, to the time I was sitting out front to try and find where and she COULD have taken me. And it was heavy rain as well, I am sure there could have been some consideration even though I was not affected and sitting out front not knowing I was there. Instead she wanted to push back my appointment to a much later date. I told her this is unbelievable and that she was being so rude and that I would reach out to the doctor about this treatment. And she hung up on me!!! Case and point. She is a homophobic rude woman and it was so obvious. I will take my business elsewhere. I was in no condition to get a reading for my EKG during that, but even more the reason to treat people better. This is a heart treatment practice it deters business and medical ethics for this area of work. In fact I am going to file as many complaints as I am able un order to help others who could risk their lives going here, especially after reading the reviews and horrible experiences. read more

Worst patient care experience. I took my dad for his appointment here with Hooman Madyoon which was at 3 pm and they took us in at 5 pm and after waiting for another 30 min , the MA came in and said . Doctor had to leave you have two choices either r/s or see the PA . Really???? They don't respect their patients and their time. This is our first and last time visiting him. read more

Terrible and irresponsible staff. Angie has no information on doctors covering for Dr. Madyoon when he is on vacation. She promises to call back and NEVER does. Dr Madyoon himself apparently cannot be bothered. Recently my father, a patient of Dr Madyoon, had a heart attack. I called to inform the Dr. He was on a European vacation. Angie didn't know who to call or who the back up cardiologist was. She assured me she would find out and call me back. Never happened. Worse, she said she would "page" the doctor. No response. My father has called from the hospital multiple times. No response. Absolutely unacceptable. We are talking about a cardiologist - acute care by definition. read more

One of the best doctors in LA area! My whole family we are going to Dr. Madyoon for years! Very professional office staff an experience doctor; Thanks Dr for all the hard work and taking care of our health read more

DO NOT GO TO THIS DR!!!! He performed a horrible surgery on me this year, not once but twice!! At this point I'm still in pain as he brushed me off like he's a small god?!?! Please do not go to him he and his PA "Jill" cannot be trusted!! If your wondering why I went twice. My leg's did not go numb until the second surgery .......... And then my legs started swelling w/ pain! And then I started to loose my circulation in both legs ... this Dr and his accomplice do not have any bed side manner whatsoever. Please I'm hoping & praying that you make a better decision in Dr's. This guy thinks he's the best just horrible I wish you the best in finding a better surgeon. read more

Hooman Madyoon, MD - Cardiologists Near Me - Los Angeles, California

Dr Madyoon. saved my life, I mean that literally. I had a heart attack and was taken to another hospital with another doctor. Dr. Lee in fact, I had an appointment with Dr. Madyoon however; my heart attack caused me to see this Dr. Lee. Dr. Lee did surgery and I kept telling him my heart was racing, it didn't feel right, I called Dr. Madyoons office o actually cancel my appointment, I spoke with Angie, she said and I quote " please keep your appointment and just talk to Dr. M. ) so I did, he immediately put a halter on me to measure my racing heart, I went back in 24 hours, he said do not go to Dr. Lee and get a stress test done, you will certainly die. I was sent to the hospital where Dr. M fixed what Dr. Lee did wrong. I am more than grateful to Angie, and Dr. M, . Dr. M has never been short with me, never been cold, never been anything but nice, he explained everything that was going on with me. He always leaves the room with ok see you next time. Very friendly. I just recently found out that my insurance is raising my out of pocket to 3000.00 a month, that's more than my monthly bills. I can't afford that, and am looking at new insurance because my widow maker is blocked. I don't trust other doctors, only Dr. M. I am afraid I am going to lose him as a doctor. Listen I am a real patient, and I am telling you yes I have waited in the waiting room, I have waited to be called back. Still I would recommend this Dr. if you are looking for the perfect doctor that caters to you and your feelings, gets you in on your appointment time, and makes you feel all giddy inside, you will never find that doctor, but this office, and Dr. M care. I personally have never had an issue. Do your research on anything any doctor tells you, I do, I trust Dr. M. It's your responsibility to advocate for yourself. If any doctor rushed me through their office and treated me like I was a dried up dog turd, I would tell them "Hey you work for me, sit down, my insurance had allocated x amount of minuets with me, don't care if we talk about the weather for the next x amount of minutes but since my insurance is paying you have two choices do your job, or I can call my insurance and tell them you refuse to treat me". Thankfully I have never had to do that with Dr. M. I trust him. I follow his orders, If I have questions, I call I ask Angie, she get back to me, maybe not in five minutes sometimes its the next day, just remember, that office gets busy. You are not the only patient, read more

I have been real patient with a real horrible experience. I went in for a basic check up and I was told I had venous reflux. I was told to come back the next day for which was called a shot that's going to fix my problem so I went in and after the so-called shot I had my whole venous reflects a vein removed till this day I have pain in my leg. I wish that I was never referred to. This doctor has to be one of the poorest mannered Doctors I have ever dealt with in my life. I have a real patient so please do not take down this review. Other people need to understand do not get the venous veins removed. This is how he makes his money. He tells everybody to do this. I got a second opinion, and the doctor told me to not do the other leg. When I told him about this on a follow up check up, he told me the doctor is an idiot and does not know what he's talking about, the doctor I saw was a lead doctor at Cedar Sinai cardiology with many awards. He would not allow me to go back and said he would not recommend doing the surgery at all. If my statue of limitation of that up, I would sue this doctor. And yelp did not remove this review. It is real you can contact me. I will send you bills from this doctor. I am a real patient. Please do not allow them to do the surgery just to make $15,000 off of your insurance biggest scam doctor ever poor bedside manners after I brought up what my doctor said he literally said he is an idiot got up and left the room. read more

Dr Madyoon has got to be the smartest cardiologist in Los Angeles, he has saved many of my friends and families lives, i just did a complete check up it and gave me some peace of mind for the moment.

I was immediately admitted to Cedars- Sinai Medical Center with chest pain and shortness of breath; I was diagnosed as needing several stents. Apparently, after being notified of my condition, Dr. Madyoon abruptly left a social event and immediately came to the hospital. He woke me up and assured me that he would perform the surgery- he said: "I got you, you're going to be OK". For over 25 years, Dr. Madyoon has dedicated his life to create an exceptional cardiology, coronary and vascular intervention practice. He is a brilliant and skilled physician. He has saved my life and today, I have a life worth waking up for. Together, with his remarkable and compassionate staff, patients are treated like family. Robert F. read more

DO NOT GO TO THIS OFFICE TERRBILE EXPERIENCE The staff are very very very rudeeee and the way they talk is very very AGGRESSIVE. I have never been to an office that the workers are very aggressive and disrespectful. MY EARS HURT FROM ONE OF HIS WORKERS YELLING AT ME JUST ASKING FOR A CONFIRMATION. This is not right at all. My ears still hurt a lot. I am not sure really whats wrong mentally with the staff working there, but they can't talk to a heart patient soooooo aggressivly and rudee. read more

I CANNOT Recommend this shady doctor. I was referred to him for a blood clot. After a thorough physical exam and questionnaire so he knew my diagnosis before he concluded with I needed surgery I felt he was doing the best for me. I was so wrong. He was over 4 hour Late for my surgery , sent no one to notify me except 30 mins prior so I sat in the recovery room 3.5 hours for him. TOTALLY UNPROFESSIONAL! Doctors overbook and try to make a lot of money at the expense of their patient. That's what was done here. 5 minutes into the surgery he was done and they closed me up without doing anything. In his surgery report, and here's where it gets to LYING and lack of INTEGRITY of the doctor. He states that until he went into my leg, he did not know it was a Chronic condition..That's an OUTRIGHT LIE!!!! He spent over 30 minutes with me taking my involved history, verbal from me where I told him EVERYTHING!!! Furthermore, he knew I had " special insurance " that pays 100% so he did it for the money. What A THIEF!!! Did nothing for me surgically, LIED about his IGNORANCE about my chronic condition. Only a moronic idiot could do worse! I called Medicare for Medicare Fraud so we will see what happens. Outrageous doctor, should have his license revoked! read more

Dr. Madyoon and his staff are great!! My dad has been a patient there for many years and we are thankful and grateful for everything they do for us. A big thank you to Angie who continually makes sure we schedule our appointments and tests and follows up and shows genuine concern about my dad's health continually. We are lucky to be in such good hands. God bless!! read more

STAY AWAY , I had a "Horrible" experience with this Doctor and his staff. Before I made my appointment to go see him I did my homework and asked Blue Shield if they will cover my yearly Cardiology checkup and they said yes, the doctor has to bill it as preventative ,So when I went in I asked them to please make sure to bill the visit as preventative so I went in to the see the doctor, His assistant did a quick E.K.G. on me and then after a few minutes he came in and went over the chart and my medical history I asked him if he will be doing a stress test or the Treadmill test or any other necessary tests he replied that My insurance would not cover those tests and he gave me some really high figures which I said I will think about it and will get back to you , so I left and I thought everything was fine and they would bill my insurance for the quick visit. After a few weeks they sent me a bill for $ 340.00 and when I called to discuss it with them they said they will not be billing for preventative since they are considered to be " SPECIALISTS" . I told them that when I came in I asked the staff member to bill it as preventative but they never told me that but they rudely brushed me off. So to make a long story short this went on for a while and after a few conversations with their very rude office manager and this other guy named Irving we never got anywhere and when I left a message to speak the Doctor Madyoon he never returned my call . Later I found out that their office reported the unpaid amount to credit reporting agencies and it went on my credit . !!!!! I should have looked at their reviews and avoided going to this Doctor , I will never go back nor will recommend them to anyone. read more

You don't have time to read long reviews so when it comes to your health you need to go to the best and most knowledgeable person. Dr. Madyoon is a fantastic human being who is a caring expert and simply one of the best in his field. He is a life saver and I may not have been here to write this review if I did not know him and let him bring me back to full health. read more

I can't say enough amazing things about this practice!!! Everyone in the office treats the patients and their family as if they were there own. The care is cutting edge and hands down EXCEPTIONAL! My father has an entirely new lease on life since they took over his care. I am FOREVER grateful!! read more

Dr. Madyoon is an exceptional cardiologist. He has been monitoring my heart health for 20+ years. I recently had several blood clots from the combination of a hormone medication and a long flight and the thoroughness of which he treated the condition and the follow up makes me feel safe in his care. Long ago when I first engaged his medical services, he would return my calls in the middle of the night and I have always felt that his dedication to the patient was well beyond expectation. I also learned (from his staff and other patients) that he has saved many people's lives who did not have health care insurance (at no charge to them) and he is also one of the first stent doctors in the world. He also treats vascular problems and once saved a limb for a patient who was about to have amputation. I am amazed at this doctor and his talents and dedication. I highly recommend his services. read more

Waited an hour, never saw him... walked out... Might want to reconsider your referral Dr

I have been a patient of Dr Madyoon for over 15 yrs, and during that time, he and his assistant Angie have done a stellar job of looking after me. Doctor Madyoon is a highly competent, experienced, open minded, kind and caring cardiologist . He is not afraid to think outside the box in order to come up with the best treatment for his patients. Angie is very responsive and highly professional. I strongly recommend Dr Madyoon and his team. read more

Hooman Madyoon is a wonderful doctor and everybody on his staff is warm, kind, very accommodating, and efficient.

I recently visited Dr. Madyoon due to issues I was having with my heart. Being only 26 and experiencing these issues with my heart was worrisome and insanely stressful. Dr. Madyoon listened to all my concerns, he truly cared about my health and well being. They took my blood and tested it for everything you could imagine and ordered all the necessary tests to make sure all my concerns were addressed. His team including his P.A Jill and his assistant Angie were all very wonderful and they made this experience not so scary. read more

Dr. Madyoon is the best cardiologist. He listened to my concern when I saw him for the first time last week. It's hard to find a doctor who is patient and knowledgeable with his practice. Not only that Dr. Madyoon is very humble which is a breath of fresh air. His office staff are very nice. Miss Angie Charm, administrative assistant for Dr. Madyoon is very kind, courteous, and accommodating. I appreciate her kind attitude and being helpful. I highly recommend Dr. Madyoon. I am glad I found him. Ellie Kaucher read more

Dr Madyoon is a rare case where his stellar reputation is matched by his humanity and you feel cared for as if he was part of your family. His vast knowledge is so impressive, you know you're in the presence of one of the greatest doctors you could possibly encounter. His Team is also stellar, particularly his PA Jill Tanner, who is spectacular! She is committed to delivering the best care one could dream of having, while being so caring and also extremely knowledgeable. I feel so fortunate for having been referred to them by a close friend.

Had to go to another doctor or facility because of poor staff attitude and long waits

We had a terrible experience here. Long wait and lack of genuine care. The explanations were short and the instructions given were not very clear. I felt we got the runaround. read more

Dr. Madyoon is the best thing that ever happened to me. My pain level from 1 - 10 was a 10. I went to Dr. Madyoon's office and he immediately diagnosed why I had such pain in my legs. He advised me that I needed surgery and it would reduce my pain. So I took his advise and the issue was resolved. I would advise anyone having an issue to make an appointment to his office. His office and staff are very caring and friendly to everyone. Comments from Pessie S. read more

Dr. Maydoon and his staff were negligent with my mother and I don't take writing this awful review for a doctor lightly. This Dr. Madyoon was my mother's heart specialist for a couple of years. She was not that impressed with the doctor citing that he was always in a hurry to go to next patient and she felt rushed and misunderstood but my mom unfortunately didn't take the time to look for another doctor who was better suited. She ended up having to do an outpatient procedure in his office and that's when it went really horrible. It was a simple procedure where they sedated her. They unfortunately released my mom when she was not yet quite alert. My mom even complained that she couldn't yet drive and she didn't feel like she should be released, but the doctor told her that she's okay to drive and made her feel wrong to not feel up to driving. My mom ended up in an accident and feel asleep behind the wheels. Thank goodness she's okay and so was the other car. Me and rest of family felt horrible because all it would have take is for her to give us a call and we would have all be more than happy to drive her home, but she felt inadequate to do this at the time because the doctor made her feel unreasonable for feeling sleepy and not up to driving. So she basically got in the car, started driving not knowing that she really isn't well. It was wrong of my mom to not trust her own instinct and drive and we also got upset at her for doing this, but she said her judgement was quite impaired at the time. This was by far most horrible experience my family has endured with a doctor who is supposed to be caring and looking after the heath of your loved one. We could have sued and were told by a lawyer that we had a solid case but my father decided in the end not to pursue this to put an end to the whole matter and move on. My mohter now has e new cardiologist and she has now realized how neglectful and awful the doctor was because of how much better she sees this new doctor is taking care of her overall and all the measures he takes to look after her health. My mother has also cut her medication in half since she is seeing the new doctor. In the end this really helped save my mom from Dr. Madyoon because he is really so interested in making money that he's sacrificing the values of being even a semi-decent doctor. read more

stay away from this dr if you don't want to get disease..!!! the dr. is so rude,and his staff is not clean at all...!!! they don't even use the new stuff for you...!!!! everything is used..!!! read more

Dr. Madyoon is an exceptionally bright and talented physician who has been treating my grandmother for the past seven years and has literally saved her life twice. My family is eternally grateful to him for all that he has done to keep her with us. He is no frills in his approach and straight forward which is exactly what we needed in order to understand her condition and get her the care that she needs. Thank you again and again, Dr. Madyoon! read more

Amazing practice. Everyone is very friendly and helpful. The PA is extremely knowledgeable and takes time to explain everything that is going on with you and what you can and need to do. What a breath of fresh air. I would refer anyone in need of these services and will be back as medically necessary. read more
