Chiropractor
Aaron Tressler D.C.
Dr. Aaron Tressler's passion for natural health and healing extends back to childhood. Growing up, he suffered with chronic gastrointestinal issues, allergies and sinus problems. His struggles through sports injuries and back pain led him to his first chiropractic experience his senior year in high school.
And then witnessing his father die from heart disease at age 50, he vowed to never allow this to happen to him and was determined to find an answer. Chiropractic care not only corrected his pain, but also his sickness, and he knew if it could change his life, it would also change the life of thousands of others.
After graduating from Slippery Rock University, and a few years into teaching physical education, his passion for health grew and it was undeniable that his mission to change lives would be through chiropractic. After receiving his Doctorate of Chiropractic graduate from Life University, Atlanta, GA in 1994, Dr. Tressler has spent the past 26+ years helping thousands of patients get their lives back. Ranging from newborn to age 99, he specializes in not only reducing or eliminating their symptoms through chiropractic care, but also enhancing their overall quality of life through lifestyle changes such as diet, exercise, weight loss, and supplementation.
Dr. Tressler is the chiropractor and owner of In8Life – Tressler Chiropractic, President of the Chiropractic Fellowship of Pennsylvania, author of 5 health books, International Chiropractic Association member, Creator of IN8LIFE weight loss system, and host of the Restoring Innate Health podcast.
Living on a farm, east of Pittsburgh, with his wife, Gabrielle, Dr. Tressler enjoys an active and adventurous lifestyle consisting of competing in rugby, raising organic cows, sheep and chickens, and playing backyard sports with his 5 children and 3 grandchildren.

Office Manager
Wendy Doerzbacher
I feel I have the best job on the planet! I love helping people feel better and I get to do it every single day. I have a strong passion for helping others reach their God-given potential.
The drive and enthusiasm I have for teaching them where TRUE health comes from is as strong and as important to me as it was when I started my career in this office 28+ years ago. I put into practice exactly what I preach, not only to my patients but to everyone one I know. As a wife and mother of 2 adult children, I have seen the direct results of how the benefits of a natural approach to health and healing can transform lives. I'm so grateful that I have the opportunity to be a part of so many patients' families and get to witness the amazing miracles we see every day in our office.

Chiropractic Assistant, Birth Doula
Emily Fry
I knew I would end up serving in a field of work that was close to childbirth and women. Since I was young I have been enthralled by the process of pregnancy and birth. The beautiful roar of a mother bringing life into this world is quite empowering and beautiful. At a young age, I was able to witness my sibling's home births.
It was an experience that I will never forget and that I blame for putting this fire in my heart. I became a doula because I know that in today's world, pregnancy and childbirth can be extremely overwhelming. I want to help mothers understand that they have so many choices to make and I want to help them make an informed one. I am honored to work alongside a community of women to serve women.

Chiropractic Assistant
Michelle Pavlik
My journey through chiropractic has been amazing. I have been a part of the In8Life office for almost 15 years. I have gained so much from working for Dr. Tressler, in which I have been able to bring to our patients but also to my own family. I am a mom of 2 kids, 4 and 10 years old, and I absolutely love seeing them thrive in their health and wellness from being a part of this chiropractic family.

Marketing Coordinator
Mackenzie Leo
As one of Dr. Tressler's daughters, I've been extremely blessed to have grown up under chiropractic care. I have understood from a young age, that by following natural health principles, we can and should be healthy and pain-free.
I have always had the heart to serve others and am grateful to support the In8Life mission, connecting with our community to introduce you to the transformative benefits of living a naturally healthy lifestyle with chiropractic care. I ran cross country and graduated from Grove City College with a Bachelor of Arts degree in Communications Studies and a minor in Sociology. I love living an active, healthy, and fun life, growing my relationships with family and friends, spending time in nature, creating art, and volunteering in the children's ministry at church.

Billing & Insurance Specialist
Lisa Riley
I love working in an environment surrounded by health and wellness. I have always led a very active and competitive lifestyle and raised four very active children. When my husband suffered an almost life-ending heart attack, with a five percent survival rate, it rocked our world and turned our lives upside down.
I realized then that we needed to do more than just be active. Back when I interviewed with Dr. Tressler he said something I will never forget, "there are four legs on a chair, and with one missing you will fall over: (1) adjustments, (2) nutrition, (3) exercise, and (4) faith.” I now try to live by this every day. I do the account receivable and billing for the In8life office, working only a few days per week. When I am not working, I watch my first granddaughter, enjoy cooking, hiking, and biking.

Paula Schimizzi
I am blessed to be a member of the In8Life staff and enjoy the opportunity to serve, inspire and motivate our patients on their journey to being the best version of themselves. I love sharing my passion for a healthy lifestyle and being an ambassador for wellness. As an avid competitive cyclist and self-proclaimed fitness nut, I can attest to the direct positive impact that In8Life's programs have had on my well-being!
