Provider very professional
Providence Patient
Never a bad experience when coming to Providence St JudeHeritage Group. Clerks, receptionists, medical assistants are always cordial and respectful. Saw PA Tran for the first time. Very impressed with her care. She listened, asked questions. Very professional and respectful. Looked into history and asked questions regarding previous conditions. Proactively ordered lab work, and prescribed necessary medications.
Providence Patient
All is good. We're happy.

Providence Patient
At the time I needed an appointment to check something that appeared to be serious. I had to go far distance away from my regular provider to get this appointment. I would have preferred staying close or with my main provider but there was no space to see me at the time. The provider that was provided was good but the distance to see them was a bit more than I prefer. I believe there's an overcrowdedness and I had to go over distance just to see somebody quickly. But I'm grateful she was there and I was able to see someone the same day that I wanted an appointment.
Providence Patient
The P A I saw for this visit is excellent. I would absolutely recommend her to anyone. Very caring. I would consider having her as my primary care. Not to happy with the one I have with your office

PA Tran was very thorough, knowledgeable and kind.
Providence Patient
This PA was very sweet and rubbed my left leg above the ankle. She slowly listened to when it hurt the most and scheduled some tests such as an Ultrasound in a week and I called the Cardiologist for an appointment on November [Date] at the Providence Hospital. Lastly, I asked if I could go to the Imperial Highway Therapy Center for help too. I called the company and they have me starting therapy on October [Date]

Very professional and pleasant visit. Feeling much better after seeing her.
Providence Patient
I've met with this provider twice when my regular doctor couldn't take a same day appointment. She is an excellent physician's assistant. She diagnosed me both times and one of those times I was so sick I felt I was going to die after a surgery where the surgeon's assistant saw me twice and never diagnosed my bronchitis.
Providence Patient
My care provider on this visit was wonderful as it always us.
Providence Patient
She answered my questions
Providence Patient
I very much appreciated the follow-up call I received two days later regarding my lab results and to check in to see how I was feeling.
Providence Patient
I've been to urgent care three times for this issue since I can't get a timely appointment with my PCP. PA Tran was the first one to actually order imaging, and likely more importantly, start the recommendation process for physical therapy.
