Dr. Marisa Sum and all the staff at Eden Valley Chiropractic are AMAZING! I first went in to get help with sciatic pain that came about from the job that I was working at the time. Dr. Marisa got me back to a place where I have no pain! I also stayed in treatment throughout my pregnancy and I truly believe that had a huge impact in my pregnancy in the best way possible. I always had a fear about pregnancy because of my past back surgery and the pain that came with it. But my pregnancy was amazing with little discomfort. Now my son who is 15 months goes and has been getting adjust since he was 1 month old.

My husband, baby and I all see Dr. Marisa. She is absolutely amazing. We started going to her because I was pregnant and my son was breech. I had low back pain that radiated into my legs for much of my pregnancy. Dr. Marisa helped clear up my lower back pain and helped support me during my pregnancy. Not enough women know the power of chiropractic for pregnancy and the benefit of seeing someone like Dr. Marisa who is a women's health advocate.

I've been to numerous Chiropractor's in the Bay Area for the pain in my neck and spine. I would get adjusted, feel some relief and still had a constant lingering pain. I started going to Dr. Marisa Sum last year and received X-rays, visual diagrams and percentages of where my bones are in misalignment. Her approach is not just making adjustments, it's about spinal correction and accuracy, to addressing the cause of pain through a gentle, holistic plan. I have experienced a transformation in my spine, posture, mobility and flexibility. I can do yoga backbends and rhythm skate now after all the years. I've referred my husband, son and other mom friends and highly recommend Dr. Marisa and all her friendly staff.

I did not think anybody without an operation could relieve the pain in my lower back. I was pleasantly surprised at the wonderful work both Dr. Sums did for me. I also enjoy coming in for my appointment, and being seen right away. The doctors and staff here are super nice and explain what and why of your ailments.

Let me start off by saying, I've been seeing a chiropractor on and off for about 18 years. I have seen a total of 4 other chiropractors and Dr. Marisa Sum has been a life changer. She understands that along with what she is doing, the patient needs to learn about what's going on with his/her body and what exercises to perform to help maintain the various curves in our spine. This has been a very eye opening experience for me and will continue to come here for a very long time.
