A structured, expert-guided program to help you support your autistic teen or young adult toward greater independence — without pushing beyond their capacity or damaging connection.

Live Coaching & Q&A with Dr. Siena

(12 Weekly 90-Minute Sessions)

Join weekly live coaching calls where you can ask questions, get specific guidance, and think through real situations.

All sessions are recorded and shared with you, so you can revisit them or catch up if you’re unable to attend live.

This is where the work becomes clearer, more personalized, and actually doable — with support as you apply it in real time.

Private Parent Community

(6-Month Access + Ongoing Support)

Connect with other parents navigating similar challenges in a thoughtfully moderated space.

Dr. Siena is actively present during the 12-week program to answer questions and support you between calls — so you’re not left figuring this out on your own.

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.

“Please give this course a try: you will find helpful content explained by a thoughtful, wise, and compassionate clinician who understands the reality of challenges of raising a ND teen and young adult….You know that knot you feel in your chest when considering your child’s future? 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.

Who is SPACE to Grow for?

Parents of autistic teens (12–18) and young adults (18–29+) who are experiencing one or more of the following:

You feel unsure how to balance support and independence

You’re seeing patterns of avoidance, resistance, or shutdown

Things feel "stuck" or not progressing over time

You want a clearer, more thoughtful approach — not more guesswork

Anxiety, burnout, or overwhelm are impacting daily life

You’re trying to help — but what you’re doing doesn’t seem to be working

Your child relies heavily on you for daily functioning

You have a vision or goal for your child’s future (e.g., college, re-entry into school), but don’t yet know how to help them get there

Who SPACE to Grow isn’t for (right now)

  • Parents looking for quick fixes or immediate results

  • Families in acute crisis who need a higher level of immediate or intensive support

  • Those not open to reflecting on their own role in current patterns

  • Situations where there is active safety risk that requires direct clinical care

“The course has exceeded expectations…So many people need this help, and it’s so hard to find qualified professionals, and this is such a brilliant way to help more people.”

— Mother of an 18 year old

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!”
