We were in and out within about an hour, which is amazing for urgent care. The front desk staff…read morewere great, very friendly and efficient. The doctor we saw was also wonderful--kind, professional, and thorough with my son. That said, I did have a very upsetting experience with one staff member. My son has claustrophobia and autism, so while waiting in the room I cracked the door open for him. A staff member came by and insisted it had to be closed, which I know isn't a rule since we've had the door cracked many times before. She pulled the door shut while my hand was still on the handle, so I naturally pulled it open again. At that point, she suddenly shouted "Don't touch me like that!"--which was shocking and completely untrue. I never touched her, and she admitted that afterward, but the outburst was unprofessional and unnecessary. After this, we were moved to another room and another provider, but no one would give me the staff member's name despite asking several times. I don't think patients should be treated this way or made to feel like they're in the wrong for advocating for their child's comfort. Overall, I do recommend this urgent care for their efficiency, the doctor, and the front desk staff. But I hope management addresses situations like this, because one bad experience can really overshadow an otherwise excellent visit.

I am extremely disappointed with the way this medical office has handled my care. I originally…read morescheduled my appointment in early April and have been waiting months to be seen. Recently, I was informed that my appointment was simply canceled due to the doctor's unavailability. I was not given a meaningful alternative or accommodation, and the cancellation was made against my wishes after I had already waited a significant amount of time for care. When I called to reschedule, I was told that the next available appointment would not be until September. In other words, because of a scheduling issue on the provider's side, I am now expected to wait several additional months to receive medical care. What makes this even more concerning is that my health has been deteriorating while I wait for treatment. I sought this appointment because I need medical care, not because it is optional. Being told that I must wait until September despite worsening symptoms is both frustrating and alarming. The only alternative offered was for me to call every day to check whether another patient had canceled an appointment so that I might be able to take that opening. This is not a reasonable solution. I work on specific days and cannot constantly call the office hoping that an appointment becomes available at a time when I am able to leave work and attend on short notice. If an opening becomes available while I am at work, I am effectively out of luck. It is unacceptable to place the burden on patients to repeatedly call the office every day in hopes of obtaining care, especially after waiting since April and while dealing with a declining health condition. Patients deserve timely access to medical treatment and reasonable accommodations when appointments are canceled through no fault of their own. As a result of this experience, I will be filing a formal grievance with my insurance provider. I hope this office improves its scheduling practices, prioritizes patients with ongoing medical needs, and shows greater consideration for those whose health may worsen while waiting months for an appointment.

I have had very different experiences with providers and staff at Optum Fontana, and unfortunately,…read moremy most recent experience was concerning enough that I feel other patients should be aware. First, I want to recognize Dr. Baidoo, who normally manages my care. Dr. Baidoo is a wonderful physician, and I would highly recommend him. As a cancer survivor, having a physician I trust and who understands the importance of continuity and timely care means a great deal to me. Unfortunately, I cannot offer the same recommendation for the nurse practitioner I saw via telehealth yesterday, Ukamaka. Following my appointment, an antibiotic that I understood would be prescribed was not sent to my pharmacy. I went into the Fontana office this morning to follow up and spoke with medical assistant Carmen, who told me that the prescription would be sent over immediately. By approximately 3:30 p.m., the prescription still had not been sent. At that point, I escalated the matter by calling Optum's Patient Care Services line, using the 800 number Optum provides in its responses to Yelp reviews. That team contacted the Fontana office on my behalf regarding my prescription. Only after that escalation did Carmen call me. The entire call lasted 18 seconds. She stated that the prescription had been sent to CVS and then hung up. I was actively trying to ask questions, but she did not remain on the phone long enough to hear what I was asking or give me an opportunity to respond. An 18-second call after a patient has had to escalate a medication issue through Patient Care Services is simply unacceptable. What makes this especially frustrating is that I had already physically gone into the office that morning and was assured that the prescription would be sent immediately. I relied on what I was told. Instead, hours passed without the prescription, I had to escalate the matter outside of the Fontana office, and when I was finally contacted, I was not even afforded the basic courtesy of having my questions heard. It should not require this level of escalation for a patient to receive medication following an appointment. A patient should not have to attend an appointment, physically return to the office the following morning, follow up on a missing prescription, wait for hours, escalate the matter to a corporate patient-care line, and then receive an 18-second phone call that ends while they are attempting to ask questions. I continue to highly recommend Dr. Baidoo, and my concerns should not be interpreted as a reflection of the excellent care I have received from him. However, based on this experience, I would not recommend receiving care from NP Ukamaka, and I would strongly caution patients about their interactions with Carmen. Patients deserve timely follow-through, accurate information, professionalism, and the basic courtesy of being allowed to ask questions about their own medical care.

I gave it one less of a star because afterwards I went to the cafeteria and they were selling blueberry pancakes, and the lady that was cooking the blueberry pancake had been wearing gloves. She ended up grabbing the door handle to get a type of ingredient in the fridge (it might have been onions because there was a guy was asking for onions for the Menudo soup) and she ended up using the same gloves to touch the onions and started chopping it. I don't understand how a lot of businesses allow people to wear gloves the entire time not being more aware that they're touching multiple surfaces and should change it. I think that is an infection control rule where you should be changing your gloves if you touch, at the very least, different handles and equipment then afterwards touching the food! That's really disgusting to see. I hope to see better awareness for the safety of the staff and members. I didnt want to take a picture of the lady but she was working today (9/4 during 0700, there were two ladies. It was the one who was cooking the first batch of pancakes since many of us were waiting for it to be cooked. she was really nice to everyone i saw interacted with her).

Terrible experience with Liliana Montoya, NP at Kaiser on Aug 1st. She dismissed my son's active…read moreyellow eye drainage as "dry eyes." I had to submit photos through a Kaiser telehealth e-visit later that same day, where an MD diagnosed an active eye infection and prescribed antibiotics--which cleared the drainage up within 48 hours. ​To make matters worse, reviewing his medical chart revealed that NP Montoya documented physical assessments she never even performed (heart/lung check, neck range of motion, ears/nose/mouth) and left out key symptoms like his sore throat. She never used a Stethescope during the visit and never washed her hands. ​Inaccurate charting and missed diagnoses are major patient safety concerns.
