Services
Shockwave Therapy
Extracorporeal Shock Wave Therapy (ESWT) uses focused sound waves to stimulate healing for chronic foot conditions. This non-invasive treatment effectively addresses plantar fasciitis, tendonitis, and bone healing issues by activating the body's natural repair processes. Clinical studies show 65-95% success rates for appropriate candidates, with minimal side effects and no required anesthesia.
Laser Nail Treatment
Medical-grade laser treatments target fungal infections beneath toenails without damaging surrounding tissue. The procedure requires no anesthesia, with most patients experiencing only mild warmth. Complete results typically appear over 9-18 months as new healthy nails grow, with no reported adverse effects or downtime required.
Diabetic Foot Care
Specialized preventive care for diabetic patients reduces amputation risks through regular check-ups and early intervention. Our services include wound monitoring, pressure point analysis, and patient education on proper foot maintenance. We collaborate with regional diabetes care programs to provide comprehensive management solutions.
Sports Podiatry
Customized treatment plans address sports-related foot injuries including plantar fasciitis, stress fractures, and tendonitis. We provide sport-specific orthotics and biomechanical assessments to enhance performance while preventing recurring injuries. Our approach combines conservative treatments with advanced recovery techniques for active individuals.
Pediatric Podiatry
Early intervention for developmental foot conditions in children, including flat feet, toe walking, and heel pain. We offer gentle diagnostic evaluations and treatment plans for common pediatric issues like ingrown nails and plantar warts, with emphasis on proper footwear guidance and growth monitoring.

My left foot hurts like walking on a stone. Doctor fixed it. Now I don't feel any pain. Thank you so much Dr. John.

I have been to the emergency department they gave me antibiotics and sent me on my way. Then a rheumatologist who suggested having my Dr refer me to a surgeon. I needed help sooner than later and my orthopedic shoe specialist "Sound Orthotics" who recommended Dr Lanthier in Sudbury. I called and was given an appointment as they just had a cancellation. I met with Dr Lanthier who suggested removing the ingrown toe nail and was able to do it right then. What a relief and a great bedside manner. Highly recommended.

After over 45 years with a foot condition, Dr Lanthier treated and cured me of my lifelong problem! It's fabulous not having sore feet. Both he and his staff are so easy to deal with. I highly recommend booking an appointment if you are having a problem with your feet or ankles.

I have been misdiagnosed with a foot problem for years. The problem was instantly recognized here and treated with confidence and I was pain and cane free after my first treatment. HIGHLY recommended.

Professional and courteous staff got me out of a jam while on vacation. I was treated with respect and familiarity from the second I walked in as a new patient until I walked out with my ailments treated.
