What are our clients are saying about us?

I really appreciate what dr. Huy Nguyen did. It’s really amazing how a simple incision can do to a usually very complicated procedure. Not everybody knows about this procedure yet but I’m pretty sure in the near future he’s going be well known and a lot of People will consider having the same procedure that I received. Not having to stay in the hospital for days is a huge thing and also not having left over scars is an amazing thing. Thank you Dr. Nguyen and the whole team for making my very first surgery a breeze.


Gallbladder Removal

I am so happy with my decision not only to have the surgery but to use Dr. Hua. The people in the office along with other doctors were so incredibly nice, compassionate and caring. I came out of surgery without the pain I was previously experiencing. I had heard so many negative comments about back surgery but after my experience with Dr. Hua and his great God given gift and his caring staff, I will recommend his office and I have, to everyone with a back problem who is contemplating surgery. Thank you! You gave me my life back!

Spine Surgery

It has been 4 months since my fusion. I am proof that this procedure works. The day before surgery, I could only walk with a cane about 60-80 feet without stopping.

Two weeks after this procedure on 3, 4, & 5 vertebra, I was able to walk a mile a day. This is the first time in 12 years I can walk with no pain or numbness. I am 68 years old and now walk 2 miles a day with no cane and pain free!

Many thanks to Dr. Sherwin Hua for this non invasive procedure, his extensive knowledge and expertise!
