Mission Hills, CA My first time to visit here. It is easy to find, plenty of parking but they don't validate though. Upon coming into the office, I was greeted immediately by an employee and gave me the paperwork's that needed to be completed. I didn't wait that long to be called. An MA assisted me, made me comfortable, ask more questions then came the doctor. It was DR. Bonni that I saw, he came to the room with a smiling face and the first time a doctor asked me, "what can I do for you?". I was taken aback and kind of tongue tied but I recovered fast enough to be able to tell him what I was there for. I like him already; he made me at ease. He listened to me then asked pertinent questions and gave me options that I can think about and decide later on to discuss when I come back for my follow up. It was a good visit for my OB-GYN. read more

See all

He delivered one of my baby's expect doctor's . He is a very understanding person and answers all ur questions u need to know

Was in for induction for my precious baby girl in March of 2024. I was supposed to have my delivery done by him (he had visited me and we spoke about what to expect and that he would be checking in on me the next day). Unfortunately, he couldn't make it, but in my postpartum room was able to help me with prescribing medications due to my complications (it was a smooth delivery but had to make sure my blood pressure was okay due to it plummeting to 90 over 20 something after my epidural worked a little too well and then during delivery my placenta was attached to my uterus still). My point being, while he might not have been the doctor to deliver my precious baby girl, he was incredible every second I interacted with him and his incredible team at Holy Cross. Thank you!!! read more

How is this man still practicing !? He gave hysterectomy total and radical. Removed ovaries, cervix, and uterus. The kicker is that it was all unnecessary as there was absolutely nothing wrong and said fibroids were not even an issue. Also close to menopause. This man didn't even provide hormonal therapy treatment after. After the botched surgery had to go in for heavy bleeding and after cries for anesthesia ,he said you can't feel anything. Could feel everything. So traumatized. Please please stay away from this man who preys on the low income Latino community to perform unnecessary procedures knowing not many can self advocate If you have been a victim, please go to the medical board and report read more

DO NOT ALLOW THIS MONSTER NEAR YOU! Especially if you're a twin mom. This man is the reason for the worst trauma of my life and ruining my body to hold future children. My twins died taking me with them a week after I asked him if I needed a specialist seeing as I'm pregnant with twins and already high risk. He laughed and said "it's me, I'm the specialist". Me and my husband both caught off guard and already scared from the previous loss he was no help with. His bedside manners are AWFUL! He's a horrible "doctor". Do not let this man near you or your body or baby. read more

Vv I will never forget what this man did to my poor mother. She came in to consult about a non symptom fibroid and got a full hysterectomy. She was unwilling thrust into early menopause with no after care or education about her situation. Shortly after the surgery she hemorrhages and I at the time 18 years old had to drive her to the hospital where he tore into her while she was writhing in pain he told her to be quiet ! Honestly had I been older and more informed I would have stepped in and slammed this man with a lawsuit. This was over 20 years ago and I will always remember this very traumatic event. Please be careful sisters. read more

I'm already upset My appointment was at 9:45 ..I came 15mins early as I was told and nobody was at the office waiting to 9:45 nobody is still here read more

Sean Kossari, MD, FACOG - Appointment was at 9:45 and nobody is here What a waste of a drive ‍‍‍ - Obstetricians & Gynecologists Near Me - Mission Hills, California

Dr. Kossari is the best, everyone in the office is so nice and helpful. Im a new patient and they make me feel as comfortable as I can be. they answer all the questions I have. As well as giving me tips on my new pregnancy. It can be nerve racking being a new mom but they help as much as they can and make me less nervous. This is the only OBGYN I would go to. Thanks doctor and staff for all you guys do for me. And thanks to my mom and sister for refering me. read more

Dr. Kossari delivered my first born child by C-Section on 5/27/17. It was not a schedule c-section , it was an emergency. I dilated 10cm and my water broke on its own but my baby just wasn't coming out. Causing my body , and my baby's body to go into stress. Dr. Kossari didn't hesitate and decided it was the best thing for me to deliver my baby by c-section. Of course that's not what I wanted nor was it in my birth plan but at the end of the day it was the right / heathy thing to do. Therefore, I am beyond happy, grateful, and thankful for having Dr. Kossari as my OBGYN. He is truly a "PROFESSIONAL" and if I ever have a baby again he will definitely deliver my baby. I can't trust anyone else after going through what I did. Dr. Kossari is very straight forward , and knows exactly what he is doing. Every nurse at the hospital told me he was one the fastest / BEST c-section doctors and he had been doing this for years. Which also made me feel very comfortable and happy I had him as my doctor. Please don't get discourage by the other yelp reviews. If you want someone who is a professional, and will make the right decision for you and your baby; Dr. Kossari is the man to go to! Once again thank you Dr. Kossari, staff members (Vanessa & Tania)! You guys are the BEST ! read more

IF YOU GET A REFERRAL FOR THIS DOCTOR REQUEST A NEW ONE IMMEDIATELY, DON'T EVEN WASTE YOUR TIME GOING TO THE FIRST APPOINTMENT. This Dr was referred to me by my primary Dr. I would not recommend this doctor to my worst enemy. He was in the room a total of about 5 minutes for an hour visit. He was disrespectful to both myself and my boyfriend. He was unprofessional and and not a caring man. The doctor that you have during your pregnancy should be a kind and caring person, something I do not think this man is capable of. He did not ask me if i had any questions and wasn't even in the room long enough for me to tell him I had questions. He barely spoke to me or my boyfriend and only spoke to my nurse and told my nurse 'Tell her...' This was supposed to be my first ultrasound appointment but he does not have an in-house tech and does not even have the appropriate machines to perform an ultrasound. This was my first OBGYN appointment, this is my first pregnancy and I am 22 years old. Thi s appointment should have been a wonderful experience for my boyfriend and myself but it was not. Dr. Kossari also inserted the speculum without putting any lubrication on it, which inevitably hurt and caused me to flinch, he then pushed it into me further causing me to flinch again. It was extremely painful and very rude. My boyfriend was very upset with how the doctor was to me and the only thing he said to either of us was a sarcastic, smart-ass remark to my boyfriend. I will not be going back to this 'Doctor'. Already contacted my primary to request a new referral for a different OBGYN. I have also reported him to Prospect Medical Group and Blue Cross for malpractice. This is not a fully functioning office, they do not have any appropriate machines to do ultrasounds. DO NOT SEE THIS DOCTOR. read more

This Dr is trash!! He was referred to me by my co-worker. I didn't even get to meet him until my 27th week!!! Meeting him for the first time was the worse experience I've had with any doctor. I showed nothing but kindness, patience and respect (regardless of all of the incorrect blood results, waiting countless hrs and them rescheduling my appointments). I expected at least an introduction from him, but I had to read his name to find out for sure if he was the OB. He wouldn't even look at me when he spoke nor did he answer my questions, all he said was "Figure it out yourself" this is my first pregnancy and I wanted to have a good experience but he ruined it and caused me sooo much stress. Do not go to this man, he is insensitive, rude and full of himself!! read more

this was my OBGYN when i was pregnant and he was the best!! Upon the first meeting, he was always attentive and supportive on all the decisions we made. He checked up daily and made sure he saw me more than once a month. helped me monitor my weight so that i didnt gain too much and that i stayed healthy through out my pregnancy. he didnt disregard anything i said or never not answer my questions. Not only is he a great doctor but also has hired a great team that will always take care of you! no quesion! he also has the state of the art Ultra sound Machine. 4D pictures and all! he was even able to make me a dvd of my sons growth in my stomach and than incorporated pictures from my pregnancy and baby shower also added songs to the dvd. he's a great doc! any woman will love him! read more

An Amazing Dr!! I have been going to Kossari for about 5 years. I have a 4 year old and a 4 month old, he delivered both my girls!! I feel very comfortable with him.. He is very caring and knowledgeable. The girls in the office are very friendly and helpful. I am very pleased here, and couldn't be HAPPIER! read more

I saw Dr Kossari for five years or so and I just found out he is not seeing any insurance patients any longer. There was no call to notify me that I needed to find a new gynecologist. This was very upsetting to me as I was being monitored by him. read more

I got assigned to Dr. Kossari 4 years ago for my son. Best experience ever. He answered any and all questions I had. Took all the precautions with my family history. He was awesome in the labor room. Now fast forward to now. I changed my insurance just to have him. I would not trust any one else to care for me and deliver my baby. People are complaining about wait times and other issues. Sure your going to wait at any good OBGYN ,ever think that he was delivering a baby and that's why he might be late?. I have never sat for long and he has always been great. Thank you Dr. Kossari for being so awesome ! read more

Dr Kossari is the best! He delivered my first and only baby girl about a year and a half ago and I couldn't be any happier to have found him! He is caring, thorough, professional and extremely down to earth. I was so paranoid my entire pregnancy and asked a million questions and not once did he disregard my concerns, he always addressed them fully and gave me extremely detailed answers. As far as my delivery, the best experience! I was scared as it was my first pregnancy, but he made it so easy for my husband and I. He is very pleasant and easy to get along with, but takes his job very seriously and I completely trusted him without a doubt during my delivery which I think is one of the most important qualities in an OB/gyn. I highly recommend Dr. Kossari! read more

He is the best dr ever!!! So comfortable with him!! Recommend him to everyone! Very clean and pleasant place. Everything is great! read more

I saw dr.kossari on November 3rd. I am extremely happy with this provider. I had to get a new obgyn because my insurance changed. I have some Issues going on and dr.kossari made me feel like there was hope and that my issue can be treated. That is such a relief. My last ongyn did anything for me. That staff is very professional and everyone is nice and welcoming. I went on a Saturday and didn't have to pay for parking. read more

Great facility. Doctor is very friendly and gets to the point. The only downside is that they take for ever to see you. They either over book their appointment slots or they're under stsff. (Yet theres only one or two other people in the waiting area). If you don't mind waiting then this is the doctor for you. read more

Best OBGYN I've ever had took very good care of my pregnancy very professional MD and staff. I was high risk and Dr kossori help me alot told me what was best so that my baby would be born healthy and thank God my baby is healthy and strong he also refers you to great prenatal care too keep pregnacy monitored I rate this place 5 star read more

HE IS HORRIBLE NOT A GOOD DOCTOR MY SON WAS A STILLBORN THANKS TO HIM RUN LADIES PLEASE RUN ANY DOCTOR IS BETTER On May 26 2014 i gave birth to my beautiful Jeremiah at 28 weeks he passed away due to a blood clot that could have been prevented if this horrible man would have giving me baby aspirin and the right meds for my blood pressure but since he would only spend 5 mins in the room and didnt place close attention to my pregnancy my son is not with me today when my son was born he said i am just happy it wasnt u and u can try again. I wasnt going to post any thing but if i can help anyone grom going through the hell I have gone through i will.

I am very happy I was able to find this dr. My choices were very limited with my ins. The girls were helpful and very nice on phone and got me in within a week unlike one other dr. I could have gone to. The other drs. office said 3 mo. wait! There is another yelp review on here saying something about don't let the office bldg. scare you? Insane! A nice normal medical office. Some people are so critical and make no sense on here. The entire office staff was very nice and professional. The dr. was very pleasant and helpful answering my questions. He will be doing a polyp removal for me in two wks. I have full confidence in his abilities. I do not understand the negative reviews on here. I feel Dr. Kossari was a great doctor. I highly recommend his office. read more

The only good thing about Dr. Kossari is he gives you an appointment quickly. If you are looking for a caring doctor, then go elsewhere. If expect to have your questions answered, he will do that about 50% of the time or less. When asking for specifics on different treatments he'll tell you to read about it, since the literature is out there. If you insist, his nurse will write the names of the alternative procedures so you educate on your own. I changed Gynecologists right away. You need to remind them to respect HIPAA rules. The clinic itself is also a dissapointment, water marks on the ceiling, bad air conditioning, tiny rooms, and small parking. read more

This was by far the worst physician I have seen. He is so unprofessional! Staff was nice ( angela was the best!), but the doctor was terrible! Don't waste your time here!!! you will be given an apt fairly quick and what not, but the service sucks. Kossari doesn't give a damn about you as a patient. He is really unfriendly and spends about 5min in the room with you and sends you away. Treats you like a number. He will yell at his staff in front of you. Overall just gives you an unpleasant and uncomfortable experience. Not to mention parking is a big B..and you have to pay for that 1 hour and half in his small waiting room to be seen for five minutes in which he doesn't listen to your concerns. Seriously, just go somewhere else. read more

This doctor is one of the best doctors I've been seen him for 14 years and I would refer every single one of my friends to him I don't know what other people are talking about specially when they haven't seen the doctor at all or having been under his care I don't think it's fair to discriminate somebody that you haven't seen before so I don't know what you guys are talking about first go see him then write a review and see if you still at your original opinion about the doctor. It's because of this Dr that I have my second son so don't you dare every single one of you say anything bad about him read more

Horrible!! Both of his offices are pretty bad but the worst was the mission hills office. Waiting room is way too small and the receptionists are not very friendly. I transferred my prenatal care to Kossari and was truly disappointed. I took in my records from my previous doctor and it seems he never even looked at it. I had gestational diabetes and I had to remind him every time I saw him! Every appointment that I got to see him he literally spent less than a minute in the room. Waited for him for 3 hours just to see him for less than a minute! He always seemed to be in a rush. It just seemed as if he didn't care for me as his patient. WILL NOT BE RETURNING TO DR KOSSARI!! read more

Dr. Kossari is the BEST, don't listen to the bad reviews. He delivered my first baby a few months ago and made me feel very comfortable, especially during labor. He answered all of my husband and my questions and concerns during our prenatal visits and even visited us before we left the hospital. His staff is very friendly and helpful too. I would definitely recommend him to anyone looking for an OB GYN. read more

Wish I can give him 0 stars worst place ever turn back they have a clinic on Osborne and Woodman worst place you can ever go to they don't care about the patient was going there since I was 2 months pregnant - 5 months pregnant and saw the doctor once and they would do their job wrong switch clinics and the first day I went to the new clinic they found out I was anemic and high risk funny how this clinic never told me anything about that and only promise me to ultrasounds when I was already 5 months my ultrasounds were already up and said I wasn't getting any more when I read the rules Medical offers you for guaranteed ultrasounds this place was the worst they don't know how to do their job and worst customer service and service ever so glad I switched read more

Dr KOSSARI is fast. Fast at everything ; he's a professional in the field. Although he's not friendly, trust me he knows what he's doing. Been with this same doctor for over 10 years and guess what... He knows me well but still treats me like he don't even know me. Yes , his attitude sucks big time but he gets the job done right . I couldn't be any happier with him and wouldn't switch. If you want a friendly talkative doctor then don't come here. I don't have all the time in the world to spend at an OBgYn office anyway so If you want a professional who gets the job done right and who is super quick then you'll be happy with him. read more

I truly love this office Dr. Kossari is very quick and efficient and answers all my questions. His staff is fantastic, Angela has been my stand out girl helping me with everything all the time, I make her do extra work unfortunately lol but she never hesitates to help out every time I call in. All the other MA's r fantastic as well. And all u other patients complaining about the wait, u wait at every doctors office no matter what! So get over it! read more

He is the best OBGYN you can find, he took me in at 23 weeks pregnant and went out of his way to make sure I got the best treatment and all the required tests I had missed. My other Dr treated me like a number, not like a person/patient. With Dr. Kossari I feel like he truly cares about his patients and is very gentle with everything he does during his exams. Everyone in the office will know you by name and they go out of their way to make you feel comfortable. I am happy with how I'm treated by everyone and how well my questions are answered. He does what's best for the patient. I recommend him to everyone! He's by far the best and I'm so thankful I found him. Give him a chance, you won't be disappointed. read more

Dr Kossari and his staff are the best! They treat us like family every time. I think the negative reviews are from people that are just frustrated with their lives. Dr is thorough and answers all my questions, I don't expect him to have to sit with me for 15 minutes, I'm sure he has more complicated patients to deal with. I've been coming here for years and will continue to do so. read more

The receptionists have no idea what they are doing. They pick up the phone as you why you are calling then out you on hold and when they get back on the phone they ask you why you are calling again like it's their first time talking to you. And that's only if you're lucky enough for them to answer the phone. Last week I had to keep calling over and over again and when someone picked up she put me on hold for 14 minutes! Then I hung up and called back and she put me on hold again and when it got to 6 minutes I hung up and decided to go online and do some research on this place. Not to my surprise they have terrible reviews with people warning that the doctor is horrible and vulgar. I found a new doctor who has great reviews and definitely would warn anyone to stay away from this place. Do your research before booking an appointment. read more

I love this doctor! Please don't listen to the bad reviews he is an amazing doctor and the clinic may not look great from the outside but when you go inside its clean and the staff is so nice they really try to get to know you its a little bit of a wait but much faster then other clinics and its worth it great doctor and nurses they are all so patient and kind especially for first time moms ! read more

I can honestly say that Dr. Kossari is an amazing Dr. He was my ob when I was pregnant with my daughter and he has seen 2 of my sister in law and we can all say he's awesome read more

I've been a patient of Doctor Kossari for over 9 years. I deem him as the best OBGYN. He listens to ALL my concerns and firmly answers my questions and considers them with much devotion. Most importantly he makes me feel very comfortable with the care he provides. In my 2 deliveries I have changed my primary hospital so I could make sure he would deliver my babies as I wouldn't trust any other doctor. His office staff provides great service from Lidia in the front office to Angela and Yari in the back office. Thank you Dr. Kossari and your office staff for an outstanding job! read more
