Why choose ONYX?

We Teach At Local Universities and Health Science Schools

Choosing a physical therapist who teaches at a Doctor of Physical Therapy (DPT) school ensures you're receiving care from someone at the forefront of the field. We instruct at Massachusetts General Hospital Institute of Health Professions, and Northeastern University Bouvé College of Health Sciences. Our role in educating future clinicians reflects a deep understanding of best practices and a commitment to high standards of care. This expertise leads to the most precise assessments, innovative treatment strategies, and better long-term outcomes.

We Specialize in Sports and Orthopedic Physical Therapy

Our home therapists are experts in sports and orthopedic care, combining deep clinical knowledge with real-world experience. We’ve worked with weekend warriors, surgical recoveries, and elite performers, delivering precision care where it matters most—your home. We don’t just follow best practices; we teach them. Our therapists train the next generation and stay current by contributing to research and speaking at top conferences. Choosing ONYX means getting care from professionals who understand movement, pain, and performance on a level few others do.

We are Dual-Credentialed as Strength and Conditioning Coaches

Choosing a physical therapist who is also a Certified Strength and Conditioning Specialist (CSCS) ensures a unique blend of rehabilitation and performance expertise. This dual qualification allows the therapist to not only address injuries but also design strength and conditioning programs that enhance overall physical performance and long term health optimization. They understand how to safely progress clients from rehabilitation to peak athletic function, bridging the gap between recovery and high-level activity. This approach is especially valuable for athletes and active individuals seeking to return to sport stronger and more resilient.
