She's always helping. She's always take care of me and looking for anything I needed, exams, blood tests, specialists. I trust her 100%. I'm so happy with her, with Marissa Nelson. And I give you 100 if I can, but it's the only thing. Thank you.

This is the second time I've felt judged and belittled by marissa Nelson. She is very rude and does not even try to be understanding or personable. When I first started seeing her she was a lot different and caring, but idk if its age or she doesn't like her career anymore, she is no longer my provider as of this last visit.
June 12, 2026
The front office staff could be a little friendlier. They're not so friendly and so welcoming. Maybe that's just one thing that you guys should train your employees on.
June 10, 2026
I liked that the doctor was very kind and attentive, and she gave me both the solutions I expected and the ones I needed. Everything was very quick, and she really helped me a lot with all my problems.

everyone from the initial contact from the attendant to the Marissa Nelson NP to the attendant who performed the EKG to the Lab people to the X-Ray tech was excellent in their care of me.

Dr. Marissa listened to me and treated me, and if I have the opportunity to see her again, I would be very happy. Thank you.

Good afternoon, my name is (PHI removed). I have absolutely no complaints about the doctor; she's excellent, very kind, and very caring. And I haven't just started seeing her recently. I've been seeing her for over a year or two. I wouldn't change her for anything. Thank you.

The entire staff was professional and efficient.
April 22, 2026
I really, really enjoyed these courses; I'd give them a 10 out of 10. The staff was very friendly, and the doctor was excellent. I would have preferred a translator present, someone who spoke Spanish, but the person we had, who was translating, was very kind and well-behaved. It was perfect, but I would have preferred a translator on-site.

Marissa Nelson is genuinely caring, did not rush me and really listened to my concerns. She included my thoughts in her plan to treat me, which made me feel like my opinion was valued and taken into consideration. She is a true asset to PIH.
April 17, 2026
It was a great experience, I felt that she was very much interested in my problem and provided the support and advice that I needed it.
April 15, 2026
I liked how she treated me, the way she listened to me and addressed my needs and doubts. In the future, if I have to return to this place, I would try to ask or suggest that Dr. Marissa Nelson from PIH specifically attend to me again.

You guys need to work on the call center for appointments. Today I was on hold for 30 minutes to get an appointment and as soon as they answered me, they hung me up and I had to call back and waited again another 23 minutes.
March 02, 2026
Okay, my experience with this provider was excellent. I felt very comfortable with her. I enjoyed that she listened to me. She listened very well and just did a very good job with exploring the differential diagnosis about what to do afterwards or what to expect and just being very compassionate. She's a good one. Thank you. Bye-bye.

Dr. Nelson is very kind, patient, professional, respectful, and listens attentively and with interest. She inspires complete confidence in me because of her diagnosis, her prompt action, and her proactive approach to preventing any more serious or enlarged problems. I was very satisfied and have already recommended her to my granddaughter, who is now her patient (PHI removed). My husband (PHI removed) is also very satisfied. Thank you, Dr. Nelson.

The visit with Marissa was informative and Great to lead to good health. The lab wait was extremely long over 2 hours. I was ok to wait but a lady with a walker looked distressed ... just as she walked in To check if her time was near .... The one and only attendant .. Had to take a break. Overall it was a good experience.
