What Sets Our Waterloo Chiropractic Care Apart

Functional Range Release® Expertise

Dr. Leis is trained in Functional Range Release (FR®), an advanced soft tissue treatment system that targets the root cause of movement dysfunction. This specialized technique addresses fascial restrictions, nerve entrapments, and joint capsule limitations that traditional approaches often miss.

Using both manual and instrument-assisted techniques, Dr. Leis delivers precise spinal and extremity adjustments to restore proper joint mechanics and nervous system function.

Beyond treatment, Dr. Leis incorporates Functional Range Conditioning (FRC®) exercises to build usable ranges of motion, strengthen joints through their full capacity, and create lasting change in how your body moves.

To accelerate healing and enhance results, our clinic offers:

  • Theralase® Laser Therapy – Advanced photobiomodulation to reduce inflammation and promote tissue repair
  • Frequency Specific Microcurrent (FSM) – Precise electrical frequencies to address pain, inflammation, and cellular dysfunction

Frequently Asked Questions

What does a chiropractor in Waterloo do?
A chiropractor specializes in diagnosing and treating conditions related to the spine, joints, and nervous system. At KW Health Connection in uptown Waterloo, Dr. Colin Leis uses chiropractic adjustments, Functional Range Release, and advanced modalities to improve joint mobility, reduce pain, and restore functional movement. Our chiropractic care helps with back pain, neck pain, headaches, sports injuries, and chronic movement restrictions.

Yes! Most extended health insurance plans in Ontario cover chiropractic care. At our Waterloo clinic, we
accept all major insurance providers and can help you understand your coverage. Many patients receive
reimbursement for chiropractic adjustments, soft tissue therapy, and therapeutic modalities. We provide detailed
receipts for easy claims submission.

Functional Range Release (FR®) is an advanced soft tissue treatment system that Dr. Leis uses alongside traditional chiropractic adjustments. While adjustments restore joint mechanics, FR® targets fascial restrictions, nerve entrapments, and capsular limitations that limit movement. This combination approach addresses both the joint and surrounding soft tissues for more comprehensive, lasting results.
Your first appointment at KW Health Connection typically takes 45-60 minutes and includes a comprehensive assessment, examination, diagnosis, and initial treatment. Follow-up appointments are usually 20-30 minutes. Dr. Leis takes the time needed to understand your condition and provide effective, personalized care.
Most patients find chiropractic adjustments comfortable and relieving. Dr. Leis uses a variety of techniques —from gentle instrument-assisted adjustments to manual adjustments—tailored to your comfort level and condition. Some patients experience mild soreness afterward (similar to post-workout soreness), but this typically resolves within 24 hours. We always communicate throughout treatment to ensure your comfort.
Treatment length varies based on your specific condition, how long you’ve had it, and your health goals. Some patients experience significant relief in 3-6 visits, while chronic conditions may benefit from ongoing care. During your first visit, Dr. Leis will provide a clear treatment plan with realistic expectations. Our goal is always to get you better as efficiently as possible.

Absolutely! While chiropractors are well-known for treating back pain, Dr. Leis helps patients with a wide
range of conditions including:

  • Neck pain and headaches
  • Shoulder pain and frozen shoulder
  • Hip and knee pain
  • Sports injuries
  • Sciatica and nerve pain
  • Joint stiffness and mobility issues
  • Post-surgical rehabilitation
  • Athletic performance optimization


Chiropractic care addresses the entire musculoskeletal system, not just the spine.
