Meet our team
Sarah Treharne, MA CCC-SLP
Founder & Director
Sarah has been living, learning, and working in the Denver Metro area since 2007. Under the mentorship and training of Dr. Patrick J. Rydell, co-author of the SCERTS Model and author of The Learning Style Profile, she developed a unique analytical approach to providing therapy for children with Autism Spectrum Disorders (ASD) within a family systems model. Sarah has taken that approach to educate colleagues nationally and to teach clinically at the University of Colorado-Boulder, where she earned her master's degree in speech-language pathology and was named the most outstanding graduate student in her class.
In addition to her clinical work, Sarah has presented on learning style challenges of children with ASD both nationally and locally. She also served as secretary of the board at The Temple Grandin School and was a Fulbright Grant recipient in 2011 (Uruguay).
Mandy Henderson, MHP

Prior to her work at the Open Door Autism Project, she served as Dean of Students at Temple Grandin School and completed a six-year tenure at Fraser, Minnesota’s largest and most experienced provider of autism services. While at Fraser, she facilitated individual, family and group skills training, and led the adolescent day treatment program.

Through her work she strives to form meaningful relationships with kids and their families, and provide them with skills, strategies and resources that serve toward the achievement of a more fulfilling life. Mandy is skilled at both making individual connections and facilitating groups, and loves to incorporate common interests like humor and music in her unique approach to building relationships.
Beth Wolf, MS CCC-SLP
Originally hailing from Chicago, Beth has been working in service of persons with neurodevelopmental disabilities since 2009. Her passion for understanding autism began at a young age as she watched her younger brother grow up in a social world with a neurodiverse brain. Beth now believes it is her calling to develop collaborative relationships with individuals, families, and communities to discover and uncover the amazing strengths that can be hidden by a diagnosis. She is passionate about empowering people across the spectrum.
Upon moving to Colorado, Beth trained at JFK Parters through a post-graduate LEND fellowship, where she gleaned extensive experience in early intervention and the diagnostic process. She then went on to work in secondary education and, most recently, at the Rocky Mountain Autism Center. Beth owes much gratitude to the guidance she received working under Dr. Patrick Rydell for his influence in her thoughtful approach to therapy.
Stephanie Nolan, OTR
Born and raised in New Jersey, Stephanie graduated from Elizabethtown College in Pennsylvania in 2009. She began her career treating pediatric patients in an outpatient clinic that primarily served children with autism and sensory processing disorders. Since then her professional experiences have spanned straightforward cases of working with children with handwriting challenges to assisting in the rehabilitation of adults with traumatic brain injuries. Additionally, she has treated fine and gross motor skills, visual perceptual skills, dyspraxia, dysgraphia, sensory processing challenges, core strengthening, and feeding.
In her varied professional experiences, Stephanie has found family education to be the common thread in delivering effective, personalized therapy. She enjoys using a sensory approach to facilitate emotional regulation and modulation, therefore, increasing clients' abilities to learn and engage with their environment and those within it. Stephanie has found that her passion for OT does not have age limits; she loves to work with both children and adults. She continues to utilize her knowledge of adult neuro-rehabilitation settings to serve as an active consultant with Can Do Multiple Sclerosis, a non-profit that provides free education and support for those with MS and their families.
