As an October 2015 graduate of Northwestern Health Sciences University, I am excited to be a part of the Human Performance Center. I look forward to focusing my research on the female athlete and developing specific testing and treatment protocols to combat the higher injury rate of women in sports. I appreciate the opportunity to work with a complex case load both in the clinic and on the sidelines.

I graduated from National University Health Sciences-Florida campus in 2015. Various bumps and bruises during my baseball career led me to seek sports medicine education via athletic training and chiropractic programs. A passion of mine is utilizing nutrition to maximize human performance, both on and off the field. I am especially excited to contribute to Northwestern Health Sciences University and the sports chiropractic community through academic research, student mentoring and clinical practice in the Human Performance Center.

I graduated from Northwestern Health Sciences University in December 2017 with an interest in sports medicine and chiropractic legislation.  I was involved in numerous sports and the corresponding injuries during high school and undergraduate, giving me a desire to help with the wide variety of injuries faced by athletes. I furthered my experience in the sports field providing sideline care for various sporting events as an EMT while at NWHSU.  I’m finishing my Masters of Exercise Science with an emphasis in concussion and whiplash injuries in April 2018.  I gained appreciation and a desire to represent chiropractic in the political atmosphere through my involvement in the Student American Chiropractic Association.  I hope to further the chiropractic profession through legislation and research in my primary field of interest: concussion diagnosis, management, and prognosis.


Dr. Beth Antoine

I come to the Human Performance Center with 12 years of athletic training experience, and have received my MS in Sports Psychology (Minnesota State University, Mankato 2010) and my Doctorate of Chiropractic from Northwestern Health Sciences University (2015). I am honored to be joining an amazing team in the Human Performance Center. My primary focus is the development of new educational material for both the CCSP and the ICCSP in combination with FICS. My research will center on the relationship between concussion and psychiatric disorders and the long term impact on the individual. This research will allow me to link together my work as a practitioner and my passion for Sport Psychology. This opportunity will help me grow both as an educator and a provider.

I look forward to working at the Human Performance Center with so many gifted and fun people. Developing relationships with the athletes, staff, interns and other practitioners is key to a successful operation and this facility definitely has that. I graduated from The School of Massage Therapy here at Northwestern in 2013 and have a deep passion for working with a variety of people. Athletes amaze me more than any other body type because of the constant demands they place on their bodies. I look forward to bringing a heightened awareness to potential patterns of tension held in the body with massage therapy and education.

Kaila Witthun, Work Study Office Assistant

I am a Chiropractic student here at Northwestern Health Sciences University. Sports and performance were a huge part of my life growing up and I'm excited to have the opportunity to continue learning from the doctors in the Human Performance Center. Working in the integrative clinic of the Human Performance Center as the student administrative assistant. I have been fortunate to see the importance of integrative care. With the help of the HPC started an integrative sports club on campus called the Student Federation of International Care-Sports (SFICS). Soon enough I hope to be a chiropractic intern with the HPC to further my knowledge of athlete treatment.
