History & Education

Dr. Karen B Hollaman grew up in Northern New Jersey with her parents and two sisters. She lived an active lifestyle balancing school with sports, music, and church activities until her sophomore year of high school when her health plummeted due to a track injury. After four years of perplexed medical professionals and being told she was a “medical mystery,” Dr. Hollaman was introduced to chiropractic and quickly learned that her body responded positively to the care. The severe abdominal pain, weight loss, and exhaustion that had caused Dr. Hollaman to fall to the floor in pain, sleep over eighteen hours a day, miss much of her junior and senior year of high school, as well as drop out of college was finally responding.

It was due to the insights of her chiropractor, who used Applied Kinesiology, that Dr. Hollaman regained her health and was able to graduate from college with highest honors and move to Alaska to experience life, work in chiropractic offices, and complete the science requirements necessary for chiropractic college. She then moved to Florida to become a massage therapist and earn her doctorate at Palmer College of Chiropractic, Florida. During her schooling, Dr. Hollaman was president of the nutrition club, class representative, and attended many seminars including the 100 hour certification program in Applied Kinesiology. She also had the opportunity to travel to Madagascar with the clinic abroad program at Palmer. In December 2008, Dr. Hollaman attained her degree as well as her dream of practicing chiropractic medicine.


After being in tremendous pain for years and finally knowing what it felt like to be healthy, Dr. Hollaman wants to prevent and help others through their own health struggles. Dr. Hollaman has helped numerous people with a myriad of health conditions. As a massage therapist and chiropractor, Dr. Hollaman brings a gentle touch and understanding heart to help empower and motivate the healing process. She appreciates, empathizes and sympathizes with the patients’ perspective and treats others, as she desires to be treated. Her goal is to educate and inspire her patient’s health potential in a positive and supportive environment. Dr. Hollaman enjoys working with adults as well as children.
