Services
Chiropractic manipulative therapy
Our spinal adjustments correct vertebral subluxations using manual, activator, and drop table techniques. This restores nervous system function, alleviates pain, and improves mobility for patients with chronic conditions or acute injuries. Treatment plans adapt to individual needs, including post-surgical patients and those with osteoporosis.
Sports injury treatment
Specialized care for sports-related musculoskeletal injuries focuses on rapid recovery and performance optimization. Combining spinal adjustments with soft tissue therapy and corrective exercises, we address joint misalignments, muscle strains, and repetitive stress injuries to restore full functionality and prevent future complications.
Headache treatment
Non-pharmacological headache management targets cervical spine misalignments and muscle tension. Through precise adjustments and posture correction, we reduce nerve irritation that contributes to tension headaches and migraines while providing lifestyle recommendations for long-term prevention.
Mechanical traction therapy
This non-surgical treatment gently stretches the spine to relieve pressure on discs and nerves. Mechanical traction helps treat herniated discs, sciatica, and degenerative disc disease by creating negative pressure that promotes nutrient flow and disc rehydration.
Therapeutic stretching
Customized stretching programs improve flexibility, reduce muscle tension, and enhance treatment effectiveness. Patients learn home exercises to maintain proper alignment, prevent reinjury, and support overall musculoskeletal health as part of their comprehensive care plan.

Great work there. Been going there literally since they opened. Every few months I go In for an adjustment and leave feeling aligned. Really good at asking how you feel and what you need from him.

Dr. Allen is excellent! I look forward to every treatment I have. The therapy beds are so relaxing after a long day at work. I appreciate the time Dr. Allen puts into my visits because he is genuine, thorough, goes above and beyond to help me feel better, and helps me understand things about insurance. His walk in policy is super convenient and he is very responsive to emails. I love that I don't ever feel rushed or like just another patient in the world of doctors. THANK YOU!
