Dr. Diener with Olympic Gold Medalist Dan O’Brien


I first visited after throwing out my back the second time in just months and 3rd time in 2 years. It was recommended that I try a chiropractor and found Bay State Chiropractic online with great reviews. I have a high deductible insurance and they have been fantastic designing a plan to keep my cost down. The staff is exceptional, warm and helpful. The doctor has such a relaxed demeanor it is a pleasure interacting with everyone. Dr. Diener goes above and beyond to provide service that fits in your schedule, cost and injury truly putting the patient first. In just two weeks time I’ve had significant improvement and look forward to a full recovery and an ongoing relationship with Dr. Diener to prevent injuries in the future.

I have been a patient of Dr. Diener for more years than I can count! After several years of pain from an auto accident, I started to see him and improved immediately! I have since been going for all kinds of issues, as well as simple maintenance. Thank you for helping me to live pain free!


Dr.Diener is by far the best Chiropractor I have ever been treated by! He helped with the pain in my lower back that I never thought would go away! I highly recommend Baystate Chiropractic! The office staff is friendly and welcoming as well! If you are looking for an amazing Chiropractor I would definitely give Dr. Diener a try! You will not be disappointed!

I haven’t been to Bay State Chiropractic for a few years. Dr. Diener is the Best! As a librarian in an elementary school, my back really got a work out with stooping and re-shelving books. Occasionally, my back would go out of alignment and I would not be able to stand up straight. It was very painful. I did not hesitate to make an urgent appointment with Dr. Diener. After the first alignment treatment, I was able to stand up straight again. It is important to schedule subsequent alignments afterwards to maintain good back health. There is a genuine feeling of well-being, physically and mentally! Thank you, Dr. Diener, for being there when I needed you!

I have been an extremely happy client for over twelve years. I’m in my early fifties and active in soccer on the weekends. I stick to my once a month adjustments and often every other week when needed during spring, fall and winter soccer seasons. Everyone is friendly that works there which is a big plus in my book.

I’ve been going to Dr. Deiner for many years and he has helped me immensely. I have also referred several people to him over the years. He keeps me and my spine in great shape. Thank you all.

I have been going here for years and I always leave feeling better than i did walking in. Dr Diener found issues that otherwise would have gone unnoticed and effected my health. GREAT customer service and extremely welcoming and friendly yet professional environment.
