Our Therapists

Miranda Materi
OTD OT/L CHT

Miranda owns and manages Hand Therapy Partners-East.

Miranda is a certified hand therapist (CHT) with extensive experience working directly with hand surgeons to rehabilitate hand trauma, surgery patients.

Miranda began working for Hand Therapy Partners in 2014. She received her professional clinical doctorate in occupational therapy from Creighton University in 2006. After practicing in hand therapy for 5 years I received my certification in hand therapy. Miranda has served as Adjunct Faculty at the Mayo Clinic in hand therapy and currently works for Northern Arizona University as adjunct faculty. Miranda has a strong interest in research development specifically in clinical settings along with treating complex patients with traumatic hand and upper extremity injuries. Miranda's other interests include musculoskeletal ultrasound and treating patients with hypermobility disorders.

Miranda enjoys working with a variety of diagnoses including flexor tendon laceration/repairs, replantations, nerve transfers, brachial plexopathies, amputation with and without prosthetics, various fractures, osteoarthritis, as well as orthotic fabrication for various conditions. Miranda is also certified in myoelectric prosthetic training and has worked with a variety of upper extremity amputees.

Miranda loves treating the more complex patients who have sustained life-changing injuries. One of the more challenging patients I’ve treated was a patient who got his arm stuck in a conveyor belt while at work. The patient actually had to break his own arm to get it out of the machine. This particular patient not only sustained an injury to the bones in his arm, but he also damaged the soft tissue including the nerves, tendons, and ligaments. He went on to have several limb-saving surgeries and required significant amounts of time in therapy. The patient went on to undergo successful hand dominance retraining and has returned to light functional use of the mutilated arm.

Josh MacDonald
MS OTR/L CHT

Josh owns and manages Hand Therapy Partners-West.

Josh is a certified hand therapist (CHT) with extensive experience working directly with hand surgeons to help rehabilitate hand trauma surgery patients. Some of the more common conditions Josh has treated include:

  • Flexor and extensor tendon injuries
  • Amputation revisions
  • Compartment syndrome
  • Soft tissue trauma and grafting
  • Digit and forearm fractures

Josh began his career specializing in pediatrics focusing on outpatient therapy, neurorehabilitation and pediatric hand therapy. In addition to caring for patients, Josh has started and managed therapy clinics and developed pediatric therapy programs for handwriting training, aquatic therapy, inpatient neurorehabilitation evaluation and inpatient therapeutic outings.

According to Josh, some of the most challenging patients have chronically stiff hands. Josh recently helped one of these patient through her recovery process. After a car accident broke most of the bones in her hand, this patient developed a severely stiff hand and fingers. She worked hard at therapy after surgery, but her progress was slow and tedious. She because understandably frustrated when she did not soon regain full motion in her injured hand. But after months of hard work, this patient was able to return to work and independent driving and self-care tasks. Not every patient can regain 100% of his or her hand functions after a severe injury, but Josh works with each patient to help them reach their highest potential.

Josh is fluent in conversational Spanish and is constantly pursuing professional education opportunities. He regularly participates in national conferences sponsored by the American Association for Hand Surgery, American Society for Hand Therapy, American Society for Surgery of the Hand, Indiana Hand Care and the Philadelphia Hand Foundation. Josh is very active in the local Crossfit community and has multiple Crossfit certifications. He also coaches children, adults and competitors.

Josh received his Masters in Occupational Therapy from Grand Valley State University in 2001 and his Hand Therapy certification in 2015.

Hand Therapy Partners–West specializes in therapy for the hand, elbow and shoulder as well as pediatric hand therapy and splinting for all upper extremity needs.
