Dr. Will saved me 14 years ago when I was pregnant and suffering from sciatica, and was spending hours in weekly physical therapy without much relief. He could work magic on me in 5 minutes! Not only is he highly effective, he is kind, generous with his time, easy to schedule with, and makes the billing stuff easy.

I've been seeing Dr. Will for the last 5 years (through 4 pregnancies now) and his care has been invaluable. I recently had a fall and injured my tailbone. I made an appointment with him as soon as possible and it was incredible the difference an adjustment made. I immediately had more range of motion. I decided to go in twice a week for the duration of my healing and I have recovered much more quickly than I expected. Thank you Dr. Will!

Serious Stress Relief! I originally saw Dr. Will for a neck injury which took a few treatments. As my neck improved, I realized the chiropractic treatments were helping to relieve stress and negative energy that I collect from day to day. By the end of a treatment all of that disappears and I'm able to reset and start again. I feel like Dr. Will releases physical blocks created by stress, and everything else works better as a result.

I've had chiropractic treatments in the past, but never with this kind of wonderful results. Dr. Will is a catalyst to my good health and peace of mind - drug free! I highly recommend Dr. Will to anyone who could use some stress relief.

Dr. Will is truly one of the best chiropractors I've ever had the pleasure to know. There's a reason why I've been going to him for adjustments for a while now. He is willing to educate you as well as talk *with* you (not down to you) about whatever your condition is. He's a great listener as well as a phenomenal doctor of chiropractic.

Dr. Will is awesome! I visit both Sonak Family Chiropractic and Western Loudoun Chiropractic to see him I always feel ten times better after being adjusted. Dr. Will makes it a priority to take care of his patients and their needs first. I would 10/10 recommend him to a friend in need of a chiropractor.

We've been going to Dr. Will for a number of years now, and have found him to be a great chiropractor. He's knowledgeable about chiropractic and natural modalities and we've found his prices to be extremely reasonable. There are chiropractic practices in the area that, in my opinion, fleece their customers and charge way to much - we've unfortunately been to some in the past. These other practices have models that seem to be designed after the modern medicine model of getting as much money out of you and your insurance as possible. Dr.

Will has a refreshingly different approach. He doesn't treat you as a revenue model, he treats you as a person. Also, if you are a pregnant woman, he has extensive experience in helping pregnant women throughout their pregnancy. While we started with him many years before my wife got pregnant, now that she is, we have the comfort of knowing he has deep expertise in treating women who are carrying. I highly suggest anyone looking for chiropractic look into Dr. Will you will not be disappointed.
