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.

Avoid this office if you value your time and peace of mind. The "communication" here is…read moredysfunctional and pathetic; calls are routinely put on hold for unbelievably excessive periods, and promises of follow-up are nothing more than lip service. Staff frequently say they'll call back, but don't, and when they do respond, it's often with inaccurate information - or none at all. Voicemails to office management are ignored entirely. The sheer lack of professionalism and accountability is staggering. Do yourself a favor and look elsewhere for medical care.

I will admit that I have never been one to keep up with my personal maintenance and I haven't been…read moreto a physician on a regular basis since I was in the Marine Corps which was 25 years ago. My new employer charges an extra $50.00 a month for my insurance if I don't get a yearly physical, but their spin is I get a $50.00 discount every month for seeing a physician once a year. Within the last year, Dr. Chang has moved to a new location ( https://bit.ly/31vpBEP ) which is near the corner of La Paz and Moulton Parkway in Laguna Hills. The space is nice for a doctor office and it is reasonably close to my home. The reception desk ( https://bit.ly/2J7YCbU ) is just inside the entrance and waiting area has a decent amount of seating. Once you name is called, the first step is getting your vitals ( https://bit.ly/2qw3CRv ) taken before you are walked to examination room. First time I had an appointment with Dr. Chang was three years ago and most of his criticism had to do with me looking like a human version of the Stay Puft Marshmallow Man. I managed to put on a few more pounds before I became disgusted with myself and lost over 80 pounds in about 6 months. I went for a physical exam because I was having some digestive distress and I guess I was due for a visit because it had been several years between examinations. Dr. Chang did listen and conducted a thorough physical which included the thrilling prostate exam. The first time he did this exam I was like "Oh, my God!" He replied, "I am just putting on the glove." On my most recent visit during the exam I moaned another doctor's name. Don't do that! "Who is Dr. Jones?" "You're the only one!" Some time in the future I will upgrade to the endoscopic examination which is more commonly known as a colonoscopy. For those not familiar with the procedure, you are put into a twilight sleep while a long, flexible tube with a tiny camera on the tip is inserted into your rectum. The camera is guided through your entire colon which basically makes you star of your own Discovery Channel special (I hope they get my good side). If Jacque Cousteau was still alive, I would definitely want him doing the narration: "Slowly, we are going up Rohlin's colon. Up ahead a steak he had in 1988." On my latest visit, I received a fist bump for the weight loss, but Dr. Chang did mention some sun damage on my head and reminded me my shiny head isn't a solar collector. We briefly discussed my diet (which is atrocious), but since I don't smoke, rarely have caffeine or alcohol and not really a fan of narcotics, I am allowing myself a vice. The lungs sound really good and my vitals are excellent for someone in my age group. Rohlinism: If you don't enjoy your vices, you should find some new ones! The only thing I messed up during this latest visit was forgetting to fast which meant I couldn't get my blood drawn ( https://bit.ly/32Id9CQ ) until the following Friday. The technician who took my blood did it right the first time and the whole procedure was over in less than five minutes. I don't have large veins, so it can be annoying at times because technicians from time to time miss my vein. I like Dr. Chang and his staff which is a good thing since I will be seeing them at least once a year for the foreseeable future!

Their billing team gave me conflicting explanations for months and still hasn't provided a clear, itemized bill. I keep getting "past due" emails even though the charge is under insurance dispute.

In a few minutes Dr Ken Iwaoka brought me a referral letter to that specific doctor!!! I thought it was a misunderstanding and asked him to refer me to someone else. His attitude changed for the worst. He started sarcastically telling me that I did not ask him that earlier. He tore the referral letter he had in his hands, told me that I should see my PCP for referrals and walked out of the room. Wow, just wow. So inpatient and rude, terrible bed side manners!!!

This concierge doctors office seemed like the real deal. Unfortunately their performance leaves a…read moregreat deal to be desired. I was sent a different patients visit and test results after my first visit, not a start to inspire confidence. I only received part of my own lab work so goodness knows where the rest ended up. They promise to set up physical therapy and exercise regimens but there is no follow-up and nothing happens. Their doctors are supposed to be on call and available to concierge patients through phone and text but it is extremely difficult to get a call back, and the office staff seem to go out of their way to be unhelpful. Calls are not returned, information is not passed on to physicians, and the entire office seems confused. They refer to themselves as a concierge practice but essentially have no idea what that actually should be. Front office staff seem nice but follow up and response is awful. Doctors get impatient with patients because they are being told by office staff that information is being sent out when it actually isn't, and the doctors don't seem to have the time to follow up on anything. A concierge practice that keeps you waiting for two months for lab results, repeatedly telling you that the lab hasn't sent them over when you know very well that Quest diagnostics have results back in a couple of days. Office staff will also tell medical staff that results have been sent out and that patients are somehow mistaken, leading to extreme frustration at the patient level. Doctors seem knowledgeable but are clearly too rushed with too many patients and a very poorly trained support staff.

I was there for my annual physical exam and was told to undress even though I wasn't there for a well woman exam. I do a well woman with my OB/Gyn. Well, it would have been nice to know I didn't need to undress completely. Needless to say, I was examined and then I was given a referral to a specialist when my request for additional testing was denied. The specialist would need to order the additional tests, according to my doctor.
