Meet the Doctor


Dr. William M. Sonak, DC

Dr. Will was born and raised in Front Royal, VA.  He graduated from William and Mary with a BS in Kinesiology in 1992.  After 3 years of “soul-searching” and volunteer work which included youth ministry and teaching high school, he entered chiropractic school in Marietta, GA.  Dr. Will graduated with honors from Life University in 1999.  He worked in two different chiropractic offices before opening Sonak Family Chiropractic in April 2002 as a Sterling chiropractor.

Dr. Will’s first experience with chiropractic was in Front Royal at age 5.  He suffered from asthma and took medications and inhalers for years.  A local chiropractor helped him breathe better which allowed him to be medication and drug free and no longer experience asthmatic symptoms.  Thus, he was destined to be a chiropractor at a young age.

Dr. Will married Alison after meeting her during his youth ministry days.  They met and wed at St. Mark’s in Vienna.  With Alison being a dietitian, they were a perfect fit.  Dr. Will and Alison have 2 children, Nathaniel, born in 2004, and Mackenzie, born in 2007.  Both were born naturally, and both have been under chiropractic care since birth.

Dr. Will is a Family Chiropractor and has a certification in pediatrics and pregnancy, which includes certification in the Webster Technique.  He is a member of the Loudoun Chamber of Commerce, Knights of Columbus, International Chiropractic Association, International Chiropractic Pediatrics Association, Virginia Chiropractic Association, and is a parishioner at St. Francis in Purcellville.  When Dr. Will is away from the office, he enjoys spending time with family and is an exercise fanatic by participating in:  running, biking, tennis, basketball, hiking, swimming, and racquetball.
