The office staff is seriously disorganized, and unfortunately it shows in how patients are treated…read more The staff often appears frustrated and unhappy, and that attitude gets taken out on patients who are already dealing with stressful health issues. Dr. Chang reviewed my sleep apnea test with me over two months ago, and together we selected a CPAP machine. Since then, I have heard absolutely nothing. After multiple follow-up calls, I was repeatedly told that the delay was due to my insurance company not approving the equipment. When I contacted my insurance directly, they informed me they could not authorize something that had never even been submitted by the office. On top of that, the patient portal constantly has problems, making communication even harder. Sleep apnea is a serious medical condition, and delays like this can directly impact a person's health and quality of life. Patients should not have to chase down basic medical follow-up or discover on their own that paperwork was never submitted. My advice: pick up copies of your exam results and consider seeing another pulmonologist.

I'm a physician and I don't get the bad reviews. I've been around a long time and to me this office…read moreis the way medical offices used to operate. She's an old fashioned family doctor that as a medical professional I find completely competent. There's APA there or an NP by the name of Michaela who is just as sharp. Extremely thorough and knowledgeable. She caught an issue on my high blood pressure meds that no one in the last 15 years has caught and by simply adding something to my meds it dramatically helped improve my blood pressure. I've read comments about not returning phone calls. She's called me twice already on some lab work. The first time she called Without me asking her to call she reviewed my blood work left me a voicemail. There was a issue with my fasting insulin which got me a little nervous I called back within 48 hours she rang me back and got me on the phone personally to address it. I asked her to create some new lab forms so I could have it tested again and she did it without question. I don't know what people expect from a doctor in today's world. There's the real world and there's the hypothetical world In the hypothetical world the Doctor will spend an hour and a half with you and find that every single issue that is of concern but in the real world to be able to survive financially a doctor cannot spend huge amounts of time with each patient and still stay in practice peter I ran a medical practice I could not spend any more than 10 or 15 minutes with each patient or I'd be out of business. Anyway this review is not about me it's about her Dr O'connor and her very excellent nurse practitioner Michaela. I have nothing but good experiences to say and I've been there 4 months now on three separate occasions. My refills are easy to do there's been no argument about running prescriptions for me I would give it a 10 out of 10. I'll add one other point that you might want to take into consideration when looking at these negative reviews. A doctor that has a six week to 8 week waiting list is a popular doctor, and he or she is a popular doctor for a reason. Think about that.

To me, this practice is dangerous. Read the newest reviews; 2024-25: 6 negative, 1 positive…read more Now make that 7 negative. When people take time to write about their concerns, that is a warning. This doctor may be competent but the practice is a complete mess. She lets an x-ray tech run the place because that person will be rude, confrontational and dismissive. So much for patient care. There are serious issues with professionalism, patient communication and follow up. There is no patient portal; phone calls are literally never returned; there is constant staff turnover and beware if you ever have to deal with the so-called medical director who is named multiple times in the reviews as in need of replacement. I second that. The doctor will not respond to calls or walk-in appointments. Even if your insurance covers it, they will not hold tele-health appointments until you put in your credit card number. What if you have no credit card or donʻt want the world to have your cc number when it isnʻt used? "Itʻs our vendor, we have no control over it." Change your vendor. This is health care, not profit care. The Physicians Assistant will not consult on the telephone. So either find a way to get to the office no matter how sick you are, or forget about it. When I did put in my credit card for the tele-health, the PA prescribed a medicine without noting that it was off the formulary. The co-pay cost me $430. The place is dark, dingy, completely unwelcoming and looks unsanitary. There is no written material to explain to new patients how to navigate the crazy way the practice operates. Staff are polite but depressed; check out Glass Ceiling to see what the staff really think about working there; it is not good. Find another doctor. This place is a nightmare.

Exceptional care from Tyler Tran PA-C! I cannot recommend…read moreMission Heritage Urgent Care enough, especially Tyler Tran. From the moment he walked in, he exuded professionalism and genuine care. He takes the time to thoroughly explain what is going on with the health of his patients, ensuring I fully understood my treatment options. His ability to break things down in an easy-to-understand way made me feel informed and empowered in my own care. He not only listens attentively and validates concerns, but he also gets straight to the point with solutions that actually work. His extensive knowledge and expertise are evident, yet he remains approachable and kind throughout the process. The clinic itself is well-run, and the staff is friendly and professional. I left feeling reassured and well taken care of. If you ever need urgent care, this is the place to go, and Tyler Tran is the provider you want to see!

The building is clean the equipment looked new and was pleasantly air conditioned. I saw Jason who was very kind and professional. He gave me the referrals I required and he had such a great sense of humor, I say that because I was in pain and it tends to make me grumpy. I try to keep it in check. However he made me laugh and forget about it for a little while. I almost wished I could've stayed longer to joke around but I knew he's busy and I was busy to go back to bed. (Spinal cord injury) so most of my days are lying on my back adjusting pillows and trying to find some comfortable position, eventually all that will go away and I can be normal again, so I appreciated all their efforts.

I know some people may hesitate because Dr. Shin is newer, but my experience with him was absolutely excellent. Before my first visit, Dr. Shin had already reviewed my medical history, which saved a lot of time and showed how thorough and caring he is. I came in for a physical and full blood work, and as soon as I checked in, Dr. Shin personally came to the lobby to ask about my concerns and what I wanted done. By the time I was in the exam room, everything was ready -- very organized and efficient! During the appointment, he listened carefully and offered thoughtful solutions before even mentioning medication. I really appreciated that he focuses on the root cause of issues, not just symptoms -- a true example of great osteopathic care. My lab results were ready within a few days on MyChart, with detailed comments from him explaining everything. Dr. Shin is an outstanding, compassionate, and knowledgeable physician. If you're looking for a caring primary care doctor who truly takes the time to listen and help, I highly recommend him!

I visited this facility with a family member and was blown away by the service and experience. The…read moreradiologist was on point, professional, and bedside manner was 10/10. He was able to answer all my questions and ease anxiety. The front desk team was equally impressive and efficient. Check in was a breeze. Upon arrival, show ID, provide insurance information, fill out intake paperwork, and wait for your name. Pretty standard. Inside was clean and welcoming with a big screen tv for those who are accompanying the patients. One thing to note is that if patients want to grab a cd there is a $10 charge per cd. Just fill out appropriate papers, sign some Hippa releases and the CD with imaging will be printed and the report printed for you separately after the radiologist has seen the images and made the report. Reports usually take about a week to be ready. My advice: wait out the report, come back and pay the $10 to have everything done and printed at the same time. Hot tip 2: parking is free, easy, and super accessible. The location of CVI is first floor and depending on where you park, right smack in the front of the building if parking from Los Altos/Plaza side.

I spent nearly four decades working for a Fortune 100 healthcare company and interacting with…read morephysicians, administrators, and executive leadership across major healthcare organizations. I can honestly say I have rarely encountered someone as hostile and unprofessional as Derrick the tech at Crown Valley Imaging in Mission Viejo. When I arrived, I began removing my jacket, watch, and jewelry simply to be cooperative. Derrick immediately became confrontational and started raising his voice, saying, "I already told you that you don't need to take off your watch and ring." This was not someone being direct or having a bad day. His tone, body language, and overall demeanor were aggressive enough that the interaction felt genuinely and completely inappropriate for a healthcare setting. I walked in calm, respectful, and friendly as I always do and was treated with open hostility from the start. Patients should never be spoken to or treated this way. Professionalism and basic respect cost nothing. Update: Upon the unbelievable interaction with the tech on Friday, I spoke with Shari the patient coordinator at Crown Valley Imaging and ask for a copy of my report once it became available and it arrived today Monday. I am upgrading my overall rating of 1 to a 3 and giving Shari 5 star rating for being really kind and professional and getting to me what she had promised. Shari Job Well Done 5 Stars out of 5 for you my friend!

(Since then, the office has rescheduled this appointment due to the doctor being unwell!). We get many texts to confirm the appointment, and then the Dr. gets sick on the day of the appointment! The same thing happened yesterday morning (December 4th)! The doctor is unwell again; therefore, the appointment is canceled! If he's sick, why did they confirm the appointment yesterday and early this morning? They suddenly canceled three hours before the appointment. When we contacted, they responded, "How about another doctor tomorrow?" Either the clinic is very disorganized, the staff is performing favors for other patients, or the doctor does not know how to conduct his business! How could the office or the doctor treat a new 90-year-old patient in this manner? The specialist at UCI referred him to us. This is completely unprofessional and insensitive. When we called today, we heard every excuse in the book and repeated "we understand, but this is the way it is" NOT GOOD!

This is the best Care I've ever been to. If there is a wait time, it's going to be minimal if you…read morehave to wait at all. Usually, I walk right in to the treatment room after signing in at the front desk. The front desk secretary who checks you in is very pleasant and sweet. Maz, the nurse is really cool and laid-back and makes you feel comfortable and totally makes you feel at ease. Then next comes the provider, PA Richard LICON. He's every provider should be at an urgent care or a doctors office or a hospital. Great bedside manner, knowledgeable, reliable and makes your experience as comfortable as possible. I have been there on the days that PA Richard is not there and it is a severe contrast you will experience to say the least. I believe it is the owner that is there on all of the other days, which is every day, but Friday, Saturday and Sunday to the best of my knowledge. I do not recommend this urgent care. Unless you go on the days that PA Richard is there which is Friday Saturday and Sunday because the provider who is I believe the owner is a condescending, rude, arrogant and overall unpleasant human being and I will never see him again that's for sure. I looked at the reviews and condescending. I think I've seen four times to describe in four different reviews of this urgent care. Thanks to PA Richard. This place is still in business, I'm pretty darn sure. So thank you to everyone there except for the owner/provider who you will unfortunately be seen by if you're there all days except Friday, Saturday and Sunday. And good luck to you if you have to go on one of the days where he's there because it will be unpleasant and rough lol.

Meanwhile the lobby area is filled they have about 8-10 clipboards untouched and stacked and after 20 minutes of waiting for them to help me while I'm standing their directly in front of them listening about their weekend for them to ask me my name, ID, medical information. Nothing finally they help and I fill out the first form of paperwork because I had been there before. The new girl can't find my name proceeds to have me fill out 3 pages of paperwork and ask for my ID and medical information after 40 minutes of waiting all the paperwork they finally announce to the entire waiting room my medical info + that I can't be seen unless I pay $100 due to my insurance not being accepted. If they had asked me for my info from the get go I would have been in another urgent care getting treated but instead I sat there in agonizing pain for 40 minutes before being told my insurance wasn't accepted. Also I did call prior to going to ensure they accepted my insurance. Instead of gossiping and chit chatting in front of all the people who are waiting for medical care do your job! Considering you signed up to be in the medical field we all could have been helped in a timely manner instead of sitting around waiting for these two women finish their conversations about their weekend plans.
