Treatment Course

The number of procedures you will need will vary based on your specific condition, the amount of time you’ve had it and other factors.

Quick & Painless

Acupuncture is quick and painless; you’re in and out of the office within 20-60 minutes.


Most patients experience reduced symptoms, even in conditions that have been present for years.

Business Manager

– Cassie

Cassie is William’s partner in life and business. They met in Chicago while he completed his Master’s of Acupuncture and Oriental Medicine, and he quickly proved to her the efficacy of acupuncture. With her background in business and his as a practitioner, they opened Affinity Acupuncture shortly after marrying and moving to Nashville. Cassie had to reduce her hours in the office when their twins were born, but some of our first clients still remember Cassie and the twins helping out back in the early days. She still comes to the office on occasion (sometimes still with the twins), but primarily works from home.

I Got My Life Back

The only reason I gave Affinity Acupuncture 5 stars is because that is the max that Google allows. My sessions at Affinity have truly changed my life. I developed neuropathy, a condition that causes your feet to feel pain, numbness, and tingling. William at Affinity diagnosed the problem and began treatment. I soon got my life back. I was able to walk and exercise again. I am about to turn 75, but now, thanks to Affinity, I feel years younger!

Pain Free

“Been dealing with a bad back (all lumbar disks compressed) for nearly a month and after one visit my back is nearly pain-free… a huge improvement from before the treatment. William was quick, professional, and kind. I’m looking forward to getting my neck and other problem areas resolved as well!”

– Mitch D

Truly Amazing Medicine

“I have been a client at Affinity for almost two years and offer my highest recommendation. William is the best and has helped me with everything I have thrown at him. He listens to his clients and provides the best and most effective treatment options available to address their needs. Each time he introduces me to a new experience, I learn to respect him more. Acupuncture can be scary to a novice, but it is truly amazing medicine and has changed my life.”

A New, Pain-Free Man

The team at Affinity Acupuncture have always been very friendly and professional. The outcome of the treatments always amaze me. I suffered from neck and back pain every day for many years. It is now a very rare day that I am in pain. I tried many treatments and therapies that didn’t work. When I completed my treatment with Affinity, I was a new, pain-free man. I highly recommend.
