 Amanda Allen - Chiropractic Assistant

Amanda is a true Austinite, born and raised here in Austin Texas!!  She attended and graduated from McNeil High School, crossed trained as a medical assistant and received her Xray license in 2009. Her Xray license led her down a Chiropractic path and after that there was no turning back.  Amanda has almost 10 years of experience with Chiropractic health and nutrition and loves seeing what a difference it makes not only for her but for others. The best part is seeing lives enriched and changed for the better without the use of medications but instead through alignment, nutrition and healthy habits.  Outside of work she spends much of her “free” time entertaining and juggling her blended family of five kids. Amanda is a big sports fan but her top favorite would be watching Pro football. Sorry Cowboys fans since she got married 5 years ago she has been converted into an Atlanta Falcon! Amanda’s other interests would definitely include cooking shared with personal organizing, knitting and playing volleyball any chance she gets.
