    Dr Tsai was very helpful and was happy to spend as much time as I needed with him. No complaints.

    Is Dr.Tsai still with One Medical in Gilbert?

    Dr. Tsai is at the One Medical office in the San Tan mall. He is still excellent and one of the best doctors I have ever seen.

    One Medical is an interesting place to review because... it's not a restaurant, and it's not an…read moreentertainment place. But it's a place you go to see a doctor. And in the spirit of Yelp... I review everything. Including... walk-in doctor's offices. So, I'm a One Medical user, and I've used it for about six months. This is my home location, and I'm definitely a fan. One of the main things I like about it is how you can get labs done by just walking in anytime. You don't need an appointment. You just walk in and wait. If there's a line, they can give you a time to come back. Or, if there's no line, you can just sit in the waiting room. It's very nice to have a lab on site, and you don't have to deal with the whole Sonora Quest adventure that a lot of us Arizonans deal with. I've seen two nurse practitioners there. Both of them were helpful. And not only did they show good bedside manner--if I'm able to use that term, despite not actually being in a hospital bed--but they also were quick to respond to my messages on the app. The service here is painless. No pun intended. It's easy to make an appointment. Their app is very well-designed. And this location is clean and friendly. I would recommend One Medical if you're looking for a simple primary care experience.

    The providers are top notch. I've been a patient for 8 years or so and my child has been a patient…read morefor maybe 6. We always get the best care and follow-through. But whoever is handling the billing lately is so rude, am not sure what happened. Maybe they outsourced it? I've never had an issue until recently. I called to clarify a charge that didn't seem like it was coded correctly. The person I spoke to on the phone was obviously busy with so many other things in the background and seemed annoyed and said she'd pass along my concern. I asked in the app and the person who replied was extremely rude as well, when I was just looking for clarification. Apparently a Saturday appointment triggers an extra $87 charge as "after hours" even though that was never disclosed and it shows on the website that they are opening alternate Saturdays (again with no mention of it being an extra fee or extra hours.) It wasn't an emergency and we didn't need to go on a Saturday. I just think that it should be disclosed somewhere that an extra fee will be incurred. My first inquiry in the app received a very patronizing "non-answer" to my question. The AI in the app is great but it doesn't handle billing. AI isn't always helpful but at least it's not rude or insulting. After the back and forth, I logged in to pay the balance that I should not have owed, but I chalked it up to a lesson learned. It showed zero balance. That was a few weeks ago, and today I got a bill in the mail showing the outstanding balance again. The providers and the quality of care are amazing. I just felt insulted the way I was treated by the billing people, and that's left a bad taste in my mouth. I would definitely recommend One Medical but be warned that billing might be a hassle now that I guess it's being handled by new people.

    Barb, you are a doctor of such personality unlike any I've ever met before. You have a deep…read moreconnection with your patients and try to lighten up everyone's day with your humor. I remember our first appointment and no one has ever left a first impression that good with me. I felt like you were my best friend right out of the gates and made sure everything was addressed and taken care of and even apologized for what I was going through. I'm always so happy to come see you. Even though dr tsai is my pcp, you keep up with him on everything that is going on and always stop me to chat and see how I am when I'm in the office. This is why I made sure my husband made you his pcp. I can't thank you enough for what you have done for him. After struggling for years with addiction, depression, anxiety, anti social issues and more you've addressed it in such a way that he is successful in so many ways with what he is doing. You worked with him and made sure that I was always informed about everything since you understand that not only was it a private matter, but a family matter and always made sure that I was informed of the care plan and always took the time to help me better understand and support him through this all. My husband hates doctors, but after meeting you everything changed. Thanks for being a part of our family and truly investing your time, heart and deepest care with us both You are an amazing woman and doctor with a spirit like no other I highly recommend you to everyone! You have saved his life and made our family whole again.

I can trust her judgement, vision, and clinical knowledge in all areas of my health care. She is insightful and shares honestly what is necessary to see me whole, whether that's physically, mentally or emotionally.

Thank you my friend!
