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.

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.

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.

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.
