Patient Reviews

"I have had 2 different consultations with Dr. Aryan about my spine issues, and he was very forthcoming about my options. He addressed all my questions, right up to the minutes before surgery as well as calling me personally afterwards. I was never more prepared going into surgery as I was for this. I could not imagine a more thorough experience." – Anastasia C. 

"I started experiencing mild back pain in my mid-teens and this condition became progressively worse over the years.  As a result, I’ve been treated by Chiropractors, Physical Therapists and received spinal injections from the onset of my back related problems. Recently, in 2013, I began experiencing extreme lumbar pain and numbness in my lower back, feet & legs and was forced to use a “walker” and getting ready to transition into a “wheelchair”.  We were concerned that the progressive nature of the numbness may become a permanent condition as well as having permanent nerve damage which controls urinary and bowel functions.  Therefore; on October 1, 2013 Dr. Henry E. Aryan performed major lumbar surgery on me. This complex surgical procedure has provided me with the level of pain and numbness relief that I was hoping for.  I’m approximately 12 months out from my surgery and the pain level in my lower back is now slight and continues to decrease as time goes by.  Also, both the sensitivity in my feet & legs has been restored as well as my lower body strength. I feel extremely fortunate to have found Dr. Aryan and his professional staff to address my back problem issues.  Dr. Aryan has provided me with the desired outcome that I had been praying for and I’ll be forever grateful to him!" -- Eric H.

"I had a fusion on my L5 on July 9, 2014. Dr. Aryan, Jonathon and Nick have been great every step of the way. Not only can I walk pain free now, I feel great. The entire office staff down to Dr. Aryan and his NP’s is the BEST! They are very compassionate, going above and beyond for their patients. I've been pleased with my whole experience, and highly recommend this office." -- Keri H.

"Great Doctors. I had surgery done by Dr. Aryan and Dr. Hanson. I have referred 9 people to Dr. Hansen and 1 to Dr. Aryan, all from my country club. They are all satisfied. I am 71 and had a knee replacement and two cervical spine fusions.  This has enabled me to continue to play golf, other activities, and enjoy life." -- Ray F.

"My experience with Sierra Pacific Orthopedics has been wonderful. The doctors are all exceptional. I was nervous about my MEG test but Dr. Wiens did a great job with very minimal discomfort."-- Jessica M.

"From the first moment my condition required surgery, I set up a meeting with Dr. Gill and Dr. Aryan. I had the upmost confidence in the kind of care I would receive.  Both doctors explained the procedures clearly. Their physician assistants and staff are a ten on my list.  My recovery from both surgeries, hip and back, has given me a quality of life that I'm thankful for every day!  At my age, 62, I can fully enjoy my grandchildren! Thank you, Dr. Gil and Dr. Aryan." -- Laurie H.

"I just want to thank everyone for all of their help in trying to fix my chronic back problem.
