Butterfly’s goal is to increase access to care, provide a convenient location for families and offer multidisciplinary services in one central location. Butterfly is an environment designed specifically for children to be fun and motivating while also being therapeutic.


Michelle Hand

Michelle’s interest in working with children started at a young age. Her first job was as a downhill Ski Instructor and she coached ski racing for children ages 6-12 for 11 years. Michelle’s interest in the body and physical fitness lead her to an undergraduate degree in Kinesiology and then naturally to a Master’s Degree in Physiotherapy. It was always Michelle’s goal to open her own clinic.

Working with children with special needs became a passion for Michelle when she was in school for Physiotherapy and inspired her to start her career at ErinoakKids Children’s Treatment Centre. Michelle’s skills as a therapist include Cuevas Medek Exercises (CME Level 3), Neurodevelopmental Treatment (NDT), functional strength and exercise, Kinesiotaping and gait training. Michelle believes in a hands-on treatment approach, and sees the potential in every child she works with, challenging them to be the best that they can be!

Opening Butterfly Paediatric Therapy with Keiri Porter was the most challenging and exciting thing Michelle has ever accomplished. Working with children of all abilities, in an environment that is created for them to thrive, is what gets Michelle out of bed every day. As a business owner and mentor, Michelle is looking forward to sharing her experiences and knowledge with the wonderful staff around her at Butterfly in hopes of growing the business and helping more children spread their wings!

Keiri Porter

When Keiri was first interested in being a Physiotherapist she was passionate about anatomy, and loved teaching. With increased experience and a few opportunities to see children, Keiri realized how inspiring and empowering it was to use play as a tool to make therapy fun and result in functional change.

As her education and career progressed, she was consistently drawn in by making meaningful physical change and creating connections with children and their families.

Keiri enjoys treating using a very hands-on approach – sometimes trying things that might fail, and being pleasantly surprised with the response. She likes to challenge the kids and then give the families ideas and tools to be involved and push their kids without it seeming like therapy. Keiri is amazed by the children that she treats every day!

The decision to start Butterfly with Michelle Hand was a work in progress over a few years, one that comes with no regrets. Having the business actually allows Keiri to treat kids on a regular basis, to make change, to impact families, to work alongside an amazing friend and therapists everyday, and now – going back to her original passion – to teach and mentor others.

Over her career she has found that what works best for her is an eclectic approach. Having different options and therapy approaches depending on the needs or sometimes even the moods of the child provides for more meaningful change. Keiri has taken her 8 week  Neurodevelopmental Treatment (NDT), has here level 3 Cuevas Medek Exercise (CME) Paediatric Kinesiotaping, Functional Strength Training, Pilates for Neurological Impairments, Body Weight support Treadmill Training and draws on these to create fun and functional treatment sessions.
