Chiropractic Care
Our chiropractic care utilizes evidence-based joint manipulation techniques from the Motion Palpation Institute to restore mobility and alleviate pain. Doctors perform comprehensive assessments to identify joint blockages, applying precise adjustments to improve spinal and extremity function. This treatment enhances nervous system communication and supports natural healing processes.
Functional Medicine
Functional medicine addresses root causes of chronic conditions through personalized nutrition plans, lifestyle modifications, and advanced diagnostics. Our practitioners analyze metabolic, hormonal, and genetic factors to create comprehensive treatment protocols that improve overall wellness and prevent disease progression.
Functional Training
Physician-led functional training programs enhance strength, power, and endurance using Dynamic Neuromuscular Stabilization techniques. Tailored workouts for athletes and general populations focus on proper movement patterns to prevent injuries and optimize physical performance in daily activities and sports.
Physical Rehabilitation
Physical rehabilitation combines DNS protocols with therapeutic exercises to restore mobility and strength post-injury. Treatment plans incorporate McKenzie method assessments, soft tissue therapy, and specialized equipment to accelerate recovery while preventing future musculoskeletal issues through biomechanical corrections.
Soft Tissue Therapy
Soft tissue therapy addresses muscle tension and scar tissue through various manual techniques and dry needling. This treatment improves circulation, reduces inflammation, and enhances tissue healing for conditions ranging from acute sprains to chronic tendinopathies like plantar fasciitis.
