I met Ellen Lui while on retreat. I was suffering from extreme neck shoulder lock up. 8 pain level. There was an immediate trust that I felt. Her gentle yet effective procedure was a beautiful experience I was totally surprised by resulting easing of the pain in my neck and the quickness of the treatment. I suspect several treatments would lead to no pain. Thank you Ellen

I went to this office for injections on my back. I had extreme anxiety and felt scared. Everyone at the office worked with me and was extremely professional and courteous. They never made me feel like a bother, let me take my time, and answered any questions I had. All of their staff is truly great! Procedure went quick and smooth and I’m so thankful for the staff.

Staff make you feel at ease while you are there. Great customer service delivery and they are constantly checking in on how you are doing. Caring and compassionate all the way through. Doctor is available during and after the procedure if you have any questions or concerns. They are also open on Saturday which is a great convenience for those of us who work during the week and cant take any time off.

By far, the best, world-class service I've experienced from a medical establishment.
Every single front-office employee I came in contact with was exceptionally courteous, respectful, accommodating, and attentive. I couldn't have asked for better service.
The physician assistant I spoke to over the phone was extremely knowledgeable and willing to go above and beyond with sharing her knowledge. She was attentive and patient in answering my questions and attending to my requests.
One of the best experiences was the cleanliness of the inside building, equipment, and patient robe. The floors were

I have to say that was the best experience I've ever had at any clinic. As soon as you walk in you're greeted. Everything was explained toe in detail of the process and what to expect. I would recommend this clinic. I was in and out by the time I knew it I was out. The staff was so amazing. Thank you very much for the awesome experience. Loved it

Always welcome once you arrive and are always willing to help their patience with their pain management. I have received a few shots here that have significantly helped my shoulder recover after my accident. I recently went to receive more shots on my lower back and was treated with care and respect. Looking forward to see how my back will improve

As a first time patient, I was scared not knowing what to expect. My experience at the clinic was phenomenal. Covid regulations are strongly enforced, the staff is extremely professional and the care is excellent. I would highly recommend this clinic to my family and friends.
