As a chiropractor myself. I was impressed, by the front desk staff, the doctors-knowledge. I highly recommend this clinic and the team.
5 stars is not good enough for how amazing these people are! Had my producer done here on 4/23/2021 with Dr. Syn. The whole process from beginning to end was pretty great (yes… the surgery process that everyone hates). The surgery center was clean and everyone had their stuff together from the moment I parked in the check-in spot, till check-out. I can never say enough about the nurses, they are the kindest people and I am so thankful to have had them there. Even though I’ve never met them before, they made me feel at ease and we’re just kind humans ❤️Definitely recommend 🤙🏼
Definitely recommend, fast easy process. They make sure your well informed on whats happening, and if your nervous they’ll talk to you about stuff that makes you happy, especially helped when i was getting my IV.
I saw Dr. Shad after my aunt recommended me to him for back pain. I had pretty bad back pain for a young adult. Upon the first appointment he felt my injury and immediately identified the area in pain and explained everything to me. My back is doing great now and I am able to go back for tissue work when needed. Never had more confidence in a doctor then I do with Dr. Shad, definitely recommend!
I’m very happy with my procedure. Thank you Dr. Javaheri and staff.
I’m very happy with my procedure. Thank you Dr. Javahert
I just had a procedure done here this morning. The center is very clean and orderly. The nurses were so friendly and kind, it was like talking to a friend. The anesthesiologist had great bedside manner and was honestly the nicest one I’ve ever met. Dr. Jenkins is very sweet and made sure I felt comfortable and informed. She is always very bubbly and makes you feel at ease. Really great people at this place! Highly recommend if you are needing a procedure done.
I have had a number of procedures done. The staff are amazing they took such good care of me. Dr. Ding communicates on a real level.Highly recommend this crew if you ever need surgery they are equipped for
My wife had surgery at your Facility. Dr Tony Mork was the surgeon. We were very impressed with your neat little surgery center. We got very personal care.. Thinking back 10 months when she had surgery we still remember well 😊
Very professional and welcoming staff,made my visit a pleasure. Thank you staff 🙂
Incredibly positive experience. Great staff.. friendly.. reassuring.Highly recommended.
The morning admittance gal who was friendly , knowledgeable and put my nervousness about surgery at ease helped me fill out the necessary forms for surgery. The next nurse prepped me for surgery and explained what would be happening. Again,very personable, organized, and knowledgeableAnother nurse came over and told me she would be helping the doctor in surgery and again explained what was going on. Friendly The orthopedic surgeon came in and spine to me about the surgery also kind and caring. Then surgery was over and I was again met with a kind nurse to help me adjust to waking up. This may all sound very routine to who ever reads this but surgery is Not, routine and it is damm scary to the patient and their families. To be taken care of by friendly, kind caring and knowledgeable staff is so important. My husband And I are grateful for the entire team here at Crown Valley Surgical. Thank you, Barbara and Jeff tatro
