Who's MJ?

Markus Jarrow is a pediatric occupational therapist with over 20 years of experience specializing in Sensory Integration, Neuro-developmental treatment, and DIR/Floortime. After two decades of integrating these models, he organically developed the The Ground upP approach - a holistic model that seamlessly supports each child through their unique developmental journey.

He’s a published author and a cofounder and former clinical director of The SMILE Center in Manhattan. He has worked extensively with clients from infancy to adolescence with neuromuscular divergences, autism, and sensory processing and learning differences, and has supervised hundreds of clinicians of OT, PT, Speech, Psychology, Social work and Education. 

Having been mentored by some of the top clinicians in the world, Markus considers himself extraordinarily fortunate. In the last decade, he began taking his work to children around the world with clinical intensives as well as designing custom sensory gyms for families both in the US and abroad. His work has taken him to Dubai, India, Bali, the Caribbean, and more.

Approaching therapy with an artist's touch

What's his Story?

Markus, a lifelong skate/snowboarder, surfer and devout meditation practitioner, deeply understands a range of sensory profiles, from the on-the-go thrill-seeking to the calm and regulated. And having dealt with social anxiety, he also empathizes with the emotional challenges and withdrawal many kids experience with verbal interactions, earning him the nickname "the baby whisperer." He has an uncanny ability for understanding a child’s sensory and emotional differences, meeting them where they are, and guiding them to where they want to go.

As a musician, Markus tends to approach therapy with an artist's touch, often using music, singing and rhythms to creatively craft sessions to each child’s individual differences. His unique approach to occupational therapy is as fun as it is effective.

Markus' love for travel, culture, and photography led him to International Therapy Intensives across several continents and in turn, Sensory Gym design. When some overseas clients lacked nearby therapy clinics, Markus began designing sensory gyms in their homes. This allowed him to meet children's sensory-motor needs and train families in effective home routines. Realizing the value of in-home treatment spaces, Markus expanded his efforts and began creating custom Sensory Gyms here in the US as well. His work combines insight, creativity, and craftsmanship to support children from the Ground upP.

Tailoring a therapeutic approach to each child's unique developmental journey

Ground upP brings together SI, NDT, and DIR/Floortime with a twist, into a hands-on, bottom-up approach that truly incompasses all aspects of a child’s development. By respecting each child and their unique developmental journeys, we build empowering relationships that become the vehicle for meaningful change. Recognizing the deep interconnection between regulation, social-emotional development, sensory processing, movement patterns, language and learning, we treat the child as a whole, supporting sustainable progress across all areas.

Comprehensive Support

Method

It’s our responsibility to dive deep beyond surface symptoms to support each child’s growth from the bottom up. As clinicians and caregivers, we have to move beyond traditional power dynamics, building rich, meaningful relationships rooted in respect and playfulness. Rather than simply instructing and telling kids what to do, we should become partners and co-pilots in their journeys, honoring their passions to fuel positive change through play.

A holistic approach, forensic in nature

What is Ground upP™?

Ground upP is a holistic approach that evolved organically throughout my career, rooted in SI, NDT, and DIR/Floortime. It’s not as much of a new intervention as it is an integrated blend of these existing methods with a twist. Though child-led, affect-based and often playfully silly on the surface, it’s a carefully calculated and forensic approach behind the scenes.

Early in my career, I realized that working without a comprehensive clinical scope was like cooking without all the ingredients. This led me to spend the next 20 years deepening my knowledge in SI, NDT, and DIR/Floortime. As I saw the potential for these approaches to seamlessly integrate, I noticed that clinicians and therapeutic organizations tended to focus on one. SI lacked the in-depth body and movement pattern components and NDT missed the depth of the sensory piece. But how can you address regulation and the sensory systems without supporting alignment and movement patterns? And vice versa? And with children on the spectrum, how do you address either without navigating the nuanced layers of the social-emotional system? DIR/Floortime then becomes the glue that guides your every interaction.

Over time, I discovered that a strong understanding of these clinical models provides the framework to not only support every child, but support the whole child: mind, body and spirit. This isn’t about managing symptoms or behaviors but treating the root systemic causes - the social-emotional, neuro-motor, and sensory processing. Each child presents with a unique mix of strengths and challenges. It’s our responsibility to dive deep below the symptoms, be playful, fun and respectful, and support each child’s growth from the Ground upP.

Integrating three models with a twist

What is Sensory integration?

Sensory integration (SI) therapy is a play-based approach aimed at helping children of all ages with sensory processing difficulties to better perceive, interpret, and respond to sensory information from their environment. This primarily includes touch, movement, sound, and vision. Each sensory system can present with heightened sensitivity (resulting in anxious avoidance), under sensitivity (resulting in seeking of more of that input) or a mix of the two. Many of the sensory systems work together in various subgroups to support different areas of function and therefore are highly interconnected and dependent on each other. Common issues include: sensory seeking behaviors, always “on-the-go”, balance and coordination challenges, motor difficulties, anxiety and withdrawal, and challenging, oppositional behaviors.

SI therapy aims to normalize any heightened or under sensitive systems and restore the collaborative functions in order to improve developmental areas, including motor skills, attention, and emotional regulation. Children learn to respond appropriately to sensory experiences, thus reducing anxiety, improving focus, and enhancing social interactions. Sensory integration is particularly beneficial for children with neuro-divergences such as ADHD, behavioral and learning challenges, autism spectrum disorder and sensory processing disorder.

Integrating three models with a twist

What is NDT?

Neuro-Developmental Treatment (NDT) is a hands-on approach that helps children with neurological issues improve functional independence. NDT focuses on improving movement, posture, and functional abilities by addressing the child’s unique motor challenges.

The therapy involves trained therapists using guided movements or facilitations to help children develop more efficient movement patterns. This includes normalizing muscle tone and alignment, enhancing postural control, and encouraging the development of both gross and fine motor skills.

NDT emphasizes the importance of the child’s active participation in the process, encouraging them to explore movements in a supportive environment following guided hands-on work. Activities may include balance exercises, mobility training, and functional play that is meaningful to the child. 

The goal of NDT therapy is to improve the child’s overall functional abilities, fostering independence in daily activities such as walking, sitting, play and self-care. By enhancing motor skills and promoting a sense of body awareness, NDT helps children reach their full potential and improves their quality of life. This approach also incorporates the involvement of family members, educating them on how to support the child's movement and development at home.

Integrating three models with a twist

What is DIR/Floortime?

DIR/Floortime is a comprehensive developmental approach that focuses on supporting emotional and social growth in children, particularly those with developmental challenges and autism spectrum disorder. DIR stands for Developmental, Individual-differences, and Relationship-based, reflecting its core principles.

The therapy emphasizes understanding each child's unique developmental profile, including their strengths, challenges, and individual interests. Therapists engage with the child in play at their level, fostering meaningful interactions that build emotional connections and relationships. Through this process, children are encouraged to communicate more effectively, think on their own and engage in problem-solving.

Floortime sessions involve playful activities tailored to the child's interests, encouraging them to explore and learn in a safe environment. The therapist may use various strategies, such as following the child’s lead, introducing new ideas, and playful obstruction to gradually expand their play and communication skills.

The overarching goal of DIR/Floortime is to enhance the child’s ability to connect emotionally with others, develop social skills, and improve overall cognitive and language development by prioritizing relationships and emotional engagement. Additionally, it encourages family involvement, empowering parents and caregivers to continue supportive interactions at home.

Guiding principles beyond the techniques

Let's get Philosophical

We’ve covered methods and touched on techniques, but what truly defines a treatment approach are the guiding principles and philosophies. Ground upP is rooted in the following:

A strong focus on foundational learning rather than isolated skills
A deeper understanding of development as a whole, not just milestones
Looking beyond surface behaviors to uncover root causes
Addressing system impairments rather than symptoms
Activating sensory and emotional systems to support lasting, functional change

Last but not least: creating a magical and supportive world tailored to each child full of affect, fun, silliness, or zen... whatever it takes to help a kiddo fully lock in, get in that shared zone, and shoot for the stars. Or as I’ve said countless times in supervision meetings: get on the river.

In loving memory

In loving memory and deep gratitude for two of the extraordinary people who came into my life and left this world too soon. I had no idea that this photo existed until a couple weeks ago when a former employee sent it to me. It will stay close to my heart forever.

Huck, my clinical journey wouldn’t be anywhere near the same without you, and so many others can say the same. Your passion for clinical excellence and sharing your craft as well as your selfless dedication to children and their families was truly second to none. I, and so many others, are forever grateful.

Sylvie, bless your heart. You were truly an angel in my life. I still remember us walking through the SMILE Center during the build out before we opened, choosing wall colors and laying out the lobby. Your loving spirit and artistic eye left a lasting impression on so many people, both in the SMILE Center and the fashion world.

May you both rest in peace xo
