Meet Dr. Siena
Psychologist, Certified SPACE provider, and parent in a neurodiverse family.
I work with families navigating complex, often stuck situations — where anxiety, burnout, and dependence have made it hard to move forward.
SPACE to Grow was built to give parents a clearer way to think, plan, and take meaningful next steps — without relying on pressure, urgency, or guesswork.
What You'll Learn
-
1) Understand how anxiety, avoidance, and executive functioning challenges interact — and why things may feel stuck
2) Assess your child's capacity in real time and adjust your approach accordingly
-
3) Shift your communication and support in ways that reduce friction and open the door to growth
4) Navigate difficult conversations and set boundaries while maintaining connection
5) Respond to resistance and escalation with more clarity, calm, and effectiveness
-
6) Build real-world executive functioning and daily living skills through structured, supported steps
7) Provide the right scaffolds as you gradually step back — so your child feels supported, not abandoned
8) Support a realistic, individualized path toward adulthood — without relying on pressure or urgency
(Enrollment opens September 2026 — spots are limited)
The SPACE to Grow Approach
-
SPACE to Grow is grounded in evidence-based approaches, with a core foundation in the SPACE (Supportive Parenting for Anxious Childhood Emotions) model developed by Dr. Eli Lebowitz at the Yale Child Study Center.
This program is an independent adaptation of these principles, tailored specifically for autistic teens and young adults.
SPACE is a parent-based treatment that focuses on shifting how parents respond to anxiety — particularly by gradually reducing accommodations while strengthening supportive, confident communication.
-
A central part of this approach is focusing on what you can control.
Rather than trying to change your child directly, you learn how to shift your own responses in a clear, structured way — creating the conditions for growth, skill-building, and increased independence over time.
-
SPACE to Grow is not a standard application of the SPACE model.
It has been specifically adapted to support autistic teens and young adults — particularly those navigating anxiety, executive functioning challenges, burnout, and demand avoidance.
This includes a focus on:
Capacity and nervous system states
Executive functioning and daily life skills
Sensory needs and regulation
Providing alternative scaffolds as support shifts
The goal is not to remove support — but to evolve it in a way that supports growth.
-
This work respects your child’s neurotype and way of experiencing the world.
Growth is not defined by becoming more typical — but by building a life that is sustainable, meaningful, and aligned with your child’s strengths and needs.

That will soften and shift and the effects of that change will ripple throughout your family.”

SPACE to Grow
What makes
-
This approach respects your child’s neurotype and way of experiencing the world.
The goal is not to “fix” or normalize, but to support meaningful, individualized growth.
-
This is not a standard application of the SPACE model.
SPACE to Grow is specifically adapted for the real-world overlap of autism, anxiety, executive functioning challenges, and PDA traits — so you can respond to the full picture, not just one piece of it.
-
You are not waiting for your child to change first.
You learn how to shift your own responses in a structured, intentional way — creating the conditions for new patterns and real progress over time.
-
You’re not left with theory.
You’re given clear tools, step-by-step plans, and guidance for how to respond in real situations — including when things feel stuck, escalated, or unclear.
-
Developed and led by Dr. Siena, a licensed psychologist and certified SPACE provider, who also brings the perspective of parenting within a neurodiverse family.
(Enrollment opens September 2026 — spots are limited)

❋

Parents looking for quick fixes or immediate results
Families in acute crisis who need a higher level of immediate or intensive support

Meet Your Guide
Dr. Siena Whitham
Hi, I’m Dr. Siena.
I’m a licensed psychologist and certified SPACE provider, specializing in supporting parents of autistic teens and young adults navigating complex, often stuck situations.
Many of the families I work with are dealing with some combination of anxiety, burnout, executive functioning challenges, and ongoing dependence — and are unsure what will actually help.
My work focuses on helping you:
Understand what’s actually driving behavior
Differentiate anxiety, burnout, and capacity limits
Shift your own responses in a structured, intentional way
Support skill-building without overwhelming your child
Move forward with more clarity and less reactivity
Why I created SPACE to Grow
In my clinical work, I saw the same pattern repeatedly:
Parents were either doing everything for their child and feeling stuck
—or—
Trying to push change and encountering resistance
There was very little guidance on how to bridge that gap.
SPACE to Grow was created to give parents a structured, supported way to move forward — without losing connection or overwhelming their child.
A personal note
I’m also a parent in a neurodiverse family.
Which means I understand this work not just clinically, but personally — the uncertainty, the second-guessing, and the constant recalibrating.
“This was way better than any book I could have read. I think I can now be the best parent of an AuDHD young adult that I'm capable of. I have the knowledge and tools for that - finally!”
— J.S.
