    My husband had a sleep study done at the Riverside facility. Unfortunately, he wasn't able to sleep…read moreso he couldn't complete the study. I didn't know what to do because my husband's pulmonologist is not from Pacific Pulmonary Medical Group Thankfully, Andrea from scheduling called me to help us make another appointment and tried her best to set us up at the earliest available she had. She was so helpful and patient, her excellent customer service is the reason I want my husband to switch his pulmonologist to one in this medical group. Thank you Andrea

    Terrible experience like many others trying to schedule here. I wrote in to their website trying to…read morerequest an appointment on April 21st. I finally ended up calling because they never replied until May 29th and when they did reply they left the string of emails on their email to me with them telling one another to respond to me so weird and unprofessional, but I let it go. When I called in I had a couple terrible experiences trying to schedule... the woman said she could not find my referral in the large stack of faxes that they have and that they were "behind"... I had my doctor send in the referral again. They sent a text with information about my appointment and it says to reply if you have any questions. I replied with a question and it took days and another text before I finally got a response. They scheduled me with a male doctor whose name is nowhere on their website. I called and asked to be scheduled with a female doctor instead (explained this was due to severe anxiety especially with male doctors)... after hours combined on the phone I finally had an appointment scheduled for a virtual appointment with Dr. Tran on July 7th! I scheduled this appointment with Dr. Tran on May 1st, but agreed to wait over two months, because I wanted a female doctor and a virtual appointment. They confirmed these details and sent me a text. Mid-June they called and left a voicemail saying Dr. Tran only does virtual appointments for follow ups and not initial appointments. I had explained during my original call that I have limited mobility, already have a CPAP machine that I've been using for years and could have my husband bring in the machine and mask if it would help to see them and I could meet on video chat for anything else. They had agreed at that time, including a call from my primary care's office who had also confirmed. So when they called with this new info in the middle of June I contacted my primary care doctor's office again and they reached out to Pacific Pulmonary to make sure my appointment was virtual and still okay for 7/7 which they confirmed it was. Fast forward a week or so, I received another call saying they had an appointment sooner and asking me to call back. I called and just got a voicemail so called again the next day. They acted like they had no idea why I was calling and confirmed that my appointment was still scheduled for 7/7 with Dr. Tran for a virtual appointment... great. I received a text on Monday of this week asking me to confirm the appointment which I did. Then, today I receive a voicemail from someone named Jessica who says the doctor said they have to move my appointment to tomorrow with some male doctor's name and to call them back so they can explain why they're moving it. Umm what?! I called back and she reiterates the same information. I told her I cannot change to tomorrow and that I had specifically asked for a female doctor which is why I was scheduled with Dr. Tran. She places me on hold and comes back and says "okay, we can keep the appointment for Monday, but you'll need to come in person". Ummm that is not an option which both myself and my primary care doctor's office had now confirmed with multiple people multiple different times. She basically acted like there was nothing else she could do so I told her to just go ahead and cancel my appointment because I've lost all trust in this office. She said okay in a very rushed voice. No, I'm sorry you've wasted over two months and who knows how many phone calls and messages to now have had absolutely nothing actually done. I would not recommend this office to anyone. I have still not received a text or email confirming my appointment has actually been cancelled. I texted the number earlier today to get some sort of confirmation, because I don't want them accusing me of missing this appointment on Monday. As you may have guessed though, they have not responded yet. Such a waste of time and not once in any of my communications have I felt valued or like they cared if I actually stayed with them. Definitely recommend avoiding if at all possible.

    So let me start off by saying I initially was looking for an appointment at the Riverside location…read more I live in the IE. After my initial phone call to the Riverside, and then days later sending an email to them, I received a call from Terry at the Irvine location. Terry immediately addressed my concerns I put in the email. He also alerted me that I was misinformed my the Riverside location, about not being able to self-refer when I have PPO insurance. My husband was/is going through a medical emergency and I was attempting to establish care and an appointment for him to get checked out. If it was not for Terry being thorough/detailed, proactively securing my husband's medical records by me answering a couple of questions, overall kind, attentive, and we would not have gotten in to see a doctor until the following week. We were booked next day, with Terry's help. As a result, I opted to make the drive from the IE to Irvine, instead of the Riverside location the very next day. Good medical practices are very hard to find these days. Terry actions demonstrated compassion and understanding of my concerns of not having my husband wait any longer for an examination. Thank you Terry! Additionally, our appointment was for 12pm. The doctor was prompt and thorough as well. The receptionist that check us in was also prompt, thorough, she showed concern when it appeared that my husband's oxygen was a tad bit low. Said for him to relax, lay back in the recliner and she would get the doctor in right away. I sincerely appreciate the team here. I'm glad Terry called. Thanks you to everyone we encountered last week.

    Worst medical group ever, the doctors always have emergency and would cancel the appointment and…read morelet you wait several months for the next appointment.
