Dr. Keith Sheehan graduated from New York Chiropractic ’97, summa cum laude and valedictorian. He currently practices nutritional therapy and chiropractic in Lancaster, PA, where he has been practicing for the past 28 years. Following a series of severe illnesses, he realized that diet and nutrition were the hidden link in his and most people’s health. His career focus has been studying and applying the theories and science of applied clinical nutrition and functional blood chemistry with his patients. He is a lecturer in nutritional and functional blood chemistry for Holistic Health Solutions, Standard Process, and the Pennsylvania Chiropractic Association. When not treating patients, Dr. Sheehan enjoys hiking, playing with his mini-poodle Sunshine, and staying in shape at the gym. He is a member of the Pennsylvania Chiropractic Association and the American Chiropractic Association. He has been voted best chiropractor in Lancaster by voters of Lancaster County Magazine 8 times.
Philosophy of Care: By combining Nutritional Blood Chemistry analysis, Foundational Nutritional Examination, and Nutrition Response Testing (Muscle Testing), I collaborate with my patients to uncover the root causes of their health concerns and create personalized, effective, holistic healing plans. As a chiropractor with a special focus on chronic pain, I empower patients to restore balance and vitality through natural, non-invasive approaches. My practice also places particular emphasis on optimizing thyroid and hormonal health, strengthening immune system function, and resolving digestive issues, guiding my patients toward sustainable wellness with compassion and expertise.

Laura Sheehan is a certified Nutrition Response Testing™ practitioner and holds a Master’s Degree in Applied Clinical Nutrition. She is also a licensed massage therapist specializing in Craniosacral therapy. Laura, a Lancaster County native, attended Millersville University and received her Bachelor of Arts in 1997. Laura has always been passionate about food, nutrition, and health. She embraced Nutrition Response Testing when she began seeing Dr. Sheehan in 1998, and her severe chronic health issues resolved 100% under his care. Over the next 20 years, she learned as much as she could about Whole Food Supplementation, Designed Clinical Nutrition, and Functional Blood Chemistry. Laura currently practices Nutritional Therapy and Functional Medicine at our Lancaster, PA office and in her own private practice in Kinzers, PA.
Philosophy of Care: Through the integration of Nutritional Blood Chemistry analysis, Foundational Nutrition Examination, and Nutrition Response Testing (Muscle Testing), I partner with my patients to address the root causes of their health challenges, considering each person’s interconnected physical, emotional, and spiritual dimensions. My practice places particular emphasis on optimizing thyroid and hormonal health, providing fertility and family health support, and functional mental health, guiding patients toward comprehensive wellness with empathy and a deep respect for their unique journey.
