About IDefine

IDefine is a nonprofit organization that exists to provide a central community for families affected by Kleefstra Syndrome (KS)

IDefine was founded in 2020 by a group of parents seeking better answers for their children and families living with a KS diagnosis.

Our Organizational Values

We are defining a new future.

We adhere to the wisdom of Nelson Mandela: “It always seems impossible until it is done.”

We enjoy the journey.

We build relationships with gratitude, laughter, and camaraderie. We embrace challenges.

We are all in.

We are 100% committed to getting the results we want.

We are relentlessly collaborative.

We are driven to find the answers. We encourage open conversation. We don’t know strangers.

We are unshakeable.

We remain “calm in the pocket” when things get tough. With laser focus, we make the uncomfortable comfortable.

We display raw authenticity.

What you see is what you get. We are real with no agendas other than to help others.
