Happy, Pain Free Patients

First, she actually cares about you, she wants you to have success, and she won’t stop till you are happy. Dr. Boutwell is very experienced in her profession and dedicated to what she does. She’s also more like family than a doctor. Very down to earth. She helps me by making me believe in myself and understanding that anything is possible and failure is not an option. I am so glad she is my doctor and you will be too. Recommendation 100 percent!

Hey Dr. Boutwell! Wow, It has been a long road since we became Dr/Patient in early 2017. I'm not sure where I would be today if not for you and your wonderful staff guiding me on that path. You are an INCREDIBLE doctor, but more importantly, a better person who always had a smile on your face! Thank you for being my doctor and hopefully my friend. Take care and God bless you!

Dr. Boutwell is a patient's dream to find. She is kind, patient, takes the time to make sure you understand everything she is saying, and answer any questions. Dr. Boutwell is continually educating herself and learning new procedures for the simple reason of helping her patients, not to display a bunch of certificates. She truly wants to help be a part of your journey of achieving a pain-free life. She has personally helped me after a car accident left me in constant pain and I am truly grateful to her.

When my husband first encountered Dr. Boutwell, we walked into her office “beat up” by surgeons and we both had a doubtful attitude she could help with the enormous pain from 3 major back surgeries. Our lives were in shambles. Pain destroys you and everyone around you. The moment she sat with us and listened to my husband's story, I knew at that moment angels walked among us... corny, right? But it’ll be 3 years this September my husband has had continued pain relief With Dr. Boutwell... something I thought would never happen. I know she saved him... she saved us. She was the light at the end of a very dark tunnel.
