Doctor Thor is extremely compassionate. She really takes her time with all my health concerns as she addresses each one at a time. She listens with care and is in no rush to get to the next patient. And that is one of the reaShow moresons she is excellent at what she does. I could’ve switched to a cheaper insurance, but I wouldn’t have been able to keep Doctor Thor as my provider. I am paying 5x more for insurance - that’s how much she means to me. I cannot lose her as my doctor. She is awesome!

Sherri T • December 18, 2025

Dr Thorhallsdottir has been my Dr for over a decade. It would not be an exaggeration to say that she has been a life saver. In addition to being knowledgeable, brilliant, patient and kind, she truly cares about her patients. She iShow mores very open minded and works with me to find solutions to often complex health problems. I have been through many health crises with her and she has seen me through the most difficult of times. She has made a huge difference in my quality of life and I am so grateful.

Dr. Thor is the most caring and wonderful physician. I am so fortunate she is my doctor.

Andrea C • February 12, 2026

Dr. Thor is an excellent doctor. I like how she is into using nutrition and exercise as a first line in heath but also uses meds as needed. She is sympathetic to loss in one’s life. Very comforting with wise words. I wouldn’t go to anyone else. Her husband, Dr. Long, is very good also. I like having a female doctor. When my husband retires, he will go to Dr. Long. He’s not wild about a female doing his prostate exam. Lol.

Pamela H • February 12, 2026

A good virtual visit with Dr. Thor since I could not go to her office. Dr. Thor is very caring and knowledgeable. Thank you, K. Jenks

Katherine J • February 10, 2026

Dr. Thor is reliable, extremely well-qualified and she listens. She has been my Primary Doctor for the past 5 years and I am very grateful for her genuine concern and her ability to navigate the complexities of Medicare to deliver excellent care. Thank you Dr Thor!!❤️❤️

Diane A • February 05, 2026

Dr. Thorhallsdottir and her team are the absolute best and have truly guided me on many health journies, they are attentive and compassionate, she even contacted me on a holiday to make sure I was okay after alarming bloodwork. I cannot praise them enough, Guardian Healthcare Angels!

Dr Thor is always kind, listens to my concerns, is responsive to my thoughts ans needs, and magically helps me feel better even in the most difficult of circumstances. I moved away from St Aug, but I won't leave Dr Thor's practice as long as she is available.

Sherri T • December 18, 2025

Dr. Thor is the best primary care doctor I've ever had. I had never said that before and don't know if I'll say it again. She listens first. She offers guidance, and helped me deal with routine and life-threatening conditions with calm, reasoned, respectful kindness. I live in another part of the state now, but use the portal to communicate and continue to schedule my annual wellness visit very year with Dr Thor.

Always a pleasure. Thank you Dr. Thor for your kindness, thoroughness, and thoughtfulness. I know that doctors, today, measure their time with patients for effectiveness and costs, but you have never made me feel uncomfortable with the extended time you've given me to discuss all matters relating to my health and wellness.
