ABSOLUTELY find another option than doing surgical procedures from MISSION SURGICAL CORONA. They did a procedure with mesh and it was not placed correctly and my hernia popped out below the incision. After it was brought to their attention they said " We only have one day to see the doctor" to show him the mistake. I have had 2 surgeons who deal in sports injuries tell me this hernia ducked under the mess because it was too shallow or not long enough. This issue has caused pain, discomfort and disfigured my stomach almost 8 weeks now. After having a discussion with the front staff about making an appointment I was told only Wednesdays are available. NOTHING ELSE. You would figure as a doctor you would be available to your patients more than one day a week. Especially, when you make a mistake. After having an argument with the staff member I was told to take it or leave it. I DEFINITELY am seeking another surgeon to correct this and to an attorney. No one should have to go Through this. read more

I wish that I could give this clinic a better rating because of the first experience that my sister and I had with them. However, I am APPALLED at the treatment and service that my sister has been given. My sister needed a lump in her breast removed, the doctor told us we could probably get in by June to get it out, and this was in MAY. They did not ever call my sister to schedule something. She had to call over and over until someone FINALLY answered her. Finally, she was scheduled for August. The surgery came and she had an appointment to have her biopsy read and check her scarring. They called the day before to cancel her appt. My sister had to call several times to reschedule. So now, three weeks after her initial surgery, she went to the corona office and the door was locked. She called and called and they kept putting her on hold. My dad had to call before they told him that they MOVED offices and never told my sister. They never notified her and didn't call her when she didn't show up to her appointment. We just wanted to know if any part of her lump was cancerous, even though we did get it biopsied before she got it removed. She asked to be referred to her regular doctor because she was disappointed in the service. They said they would send her doctor the results and had an appt today. She went and THEY DIDN'T SEND HER RESULTS. We are now on a MONTH of not having her scar checked or knowing if she has breast cancer. It is ridiculous, and disappointing that if something was wrong, there would be a time where we didn't know and it could get worse. I am truly disgusted, and quite frankly nervous to put my sister'ss health in their hands. read more

Very in organized clinic had appt at 330 was made to wait to 530 just horrible dr.shin was my doctor looks like he's to busy

Edit: A woman by the name of Irene stepped in and got everything settled for my surgery and even got me an appointment this week. I am pleased with the outcome; as she apologized for the inconvenience several times and from the sounds of it she really tries to keep this place running smoothly. Irene is not only a star in how helpful she is but she bridges the communication between everyone and gets all parties on a perfect page and makes things happen! This place is awful; the worst part of is that they know they are awful and continue to operate poorly. This isn't a taco stand, this is a medical facility and they need to treat it as such. I have a painful breast mass. It's already been painful over two months with the process of me seeing a few doctors, getting this referral and then waiting for them to schedule me 3 weeks out. Now it's been 2 weeks and 3 days and I still haven't heard back about my surgery; which will also end up being scheduled several weeks out. It's ridiculous. read more

I'm giving this place 1 star because they are incredibly difficult to reach and rarely ever return calls. I tried for weeks to get ahold of the surgery scheduler, calling multiple times a day. I was never able to get a call back. Finally the receptionist left a note for her and she called me back weeks of waiting. After my surgery I scheduled a follow up, which was canceled days before. I made a new appointment, then when the day came I went to the office and the door was locked. I knocked and waited with no answer (my appt was at 10:30am) . I tried calling the office for hours, either with no answer or being on hold for a long time. Finally they answered and let me know they had moved offices! No one had attempted to reach out prior to my appointment to inform me of the move. Additionally, the old address, the one I went to, is still listed as their address in google AND their website!!! They are impossible to work with or to even speak with. It's been three weeks since my surgery, my follow up was supposed to be a week after... This place is incredibly disappointing, especially since the doctor was very nice and professional. They just don't know how to run an office. read more

Dr. Michael Tran is phenomenal! He was actually my second opinion surgeon and he made me feel so much more comfortable about my procedure. He was very patient, explained the surgery, and all around a caring and professional surgeon. I am so glad that I chose to go with him and his course of action on my surgery. I would highly recommend him to my friends and family. The office staff was very kind and helpful and the entire experience was very pleasant (well as good as it gets when having to have a surgery at least!). 5-stars, two thumbs up, great job Mission Surgical Clinic!! read more

Dr. Tran is an excellent surgeon whom has taken great care of my stepdad during his journey with esophageal cancer and is now cancer free. His staff provides great customer service.Our family would highly recommend this office and Dr. Tran. read more

Thank you from the bottom of my heart to Dr. Tom Lin (my surgeon) and his wonderful staff, especially Ms. Jasmine Macias for your support and your help during my lumpectomy surgery. Dr. Lin was excellent and very kind. And for that I am very grateful! read more

It seems that caring for patients is low on their priority list here! I had been to their Riverside location back in early 2020 and the staff was great and extremely helpful. I found myself in need of surgery yet again early this year and was happy when my insurance referral came in as Mission Surgical in Corona (this was back in April). They were booked out over 3 weeks for appointments, which when you are in pain feels like an eternity. I saw Dr Christina Lien and she was very nice, I was in a hurry but she was thorough and respected my time. It has now been 3 weeks since my visit and I can't get anyone to call me back. I had to call my insurance company because mission surgical said my authorization for surgery was still pending in the system after 2 weeks. Called insurance and my auth was declined due to a technical error, luckily they were able to approve my surgery right there with me on the phone. I called back and gave the authorization # and asked to speak with the scheduler, Maria. I have yet to hear back after a week and despite multiple attempts to reach her/messages left with the receptionist and on her voicemail. I understand that people are busy but when a call cannot be returned in a weeks time it feels like they do not care about you at all. While the Surgeons might be great, I would not recommend this place to anyone unless you are not in a hurry or not in any pain and don't mind waiting. read more

This is for Roberta, she schedules the surgeries. Although all of Dr. Chin's staff is awesome, Roberta is a rock star. Roberta went above and beyond to ensure that my son was being taken care of. Her empathy and genuine concerns for his health warmed my heart and brought me to tears. Her excellent customer service was truly appreciated. I would also like to recognize Christina, the nurse in the office. Always greets us by name and with a smile. read more

Dr. Michael Tran Did A TERRIFIC Job removing my husband Gallbladder and he's healing very well I will recommend him to Family and Friends. Thank You Dr.Michael Tran From Mr. and Mrs. Robert & Shaunna Thomas Sincerely yours, Mrs. Shaunna Thomas read more

To Dr. Michael Tran; great person, great surgeon, great bedside manners. Very conscience of what he does. He operated on my mother, removed gallbladder laparoscopically, (when other surgeons would of done it full open surgery) she is having a speedy recovery thanks to that. Five stars review. read more

Dr. Husted (spelling may be incorrect) was awesome. I did wait about 40 minutes before I was seen then after my blood pressure was taken another 10 or so. I'm used to waiting in doctors office, but I appreciated how he apologized for me having to wait, multiple times. I am getting a cyst removed in my leg and the other times I have had it looked it there were always half assed answered. I went to a well know dermatology place and the doctor couldn't even give me a good time frame I would be out from working out. The doctor here gave me a full run down what to expect, how they'd do it, why and even let me know I wouldn't even be restricted to workout, but to go off feel. It was a quick consultation but it was the most efficient and most informative. He was very helpful and his demeanor was great. Very rare do I get that good of a first impression from a medical office. A little bit goes a long way. read more

This clinic is so professional. The office staff are wonderful. Dr. Saeed is terrific and he takes the tine to explain everything to you. He answered any questions and takes his time with me as a patient. read more

Extremely disappointed with Dr Tran office and staff. I was told I needed to go get lab work done & that they would fax over the paper to the lab and I should be able to go the following day. I had to make special arrangements to have someone take care of my special needs son the following day. I ran to Quest Lab only to find out that Dr Tran office never faxed over the lab work. I called the office and I was told that the girl in charge of the lab work was on a break and I had to wait for her to get back (so mad). Fast forward 3 weeks later after I got my gallbladder removed and needed my follow up so I called made an appointment with Dr Tran at 2:30pm becomes apparently he doesn't see patients in the morning. When I showed up to the Corona office there where about 6-7 patients waiting in the hall way. Some of them were sitting on the floor, others trying to knock on the door. I decided to call office & lady that answered said the office was closed and someone changed my appointment for 10am versus 2:30pm without even calling me!!!! When I told everyone in the hall way that the office was closed they all started yelling and saying nobody called them. They need to fire whoever said they called all the patients to cancel the appointments. I am done with this stupid office read more

I have nothing but good things to say about Dr Tran and his staff team saved my life. I underwent emergency surgery and Dr Tran was my surgeon he did an amazing job. His staff was so nice and professional. I am so grateful that I ended up with Dr Tran as I am much better now after my surgery. read more

Dr. Changchien, He was wonderful! He was very thorough by explaining and detailing my entire procedure. He stayed in my consult until all my questions were answered. read more

The front office people, especially in the Riverside office are very unfriendly and disrespectful..they know better than patients and are bery rude. As for doctors: I had 3 surgeries by Dr. Changchien-Misdion Surgical staff, a wonderful surgeon, very knowledgeable, excellent bed-side manners. each time he was at the hospital every day to keep me up to date. Unfortunately he moved on to Kaiser (their win) I ended up with a Dr. Tran. The 1st post-surgery appt, it became obvious he had not even read my file and was totally unfamiliar with my case and post-surgical complications I had experienced. Each time it was more and more difficult even to communicate with him. In fact , he released me without even telling me straight he was doing so...I am having another surgery - hernia repair- as result of a staph infection while still in the hospital, he didn't even concerned himself with any post complications. I asked my PCP to make sure I was not sent to Dr. Tran and/or to Mission Surgical! As my husband very well expressed himself.."we are done with this group"! Be careful!!!! read more
