We use a team-based model, which means we work together, sharing a single philosophy to offer outstanding services to children and families. We are leaders in the community, regularly developing innovative treatment techniques. As part of a commitment to continual learning, we attend workshops and classes to expand our skills and stimulate our thinking. We work closely with other professionals within our Insight Collective team as well as within the broader community. Each member of the team brings experience, creativity, enthusiasm, dedication, empathy, and warmth to her work.

Dante, TDI Certified Therapy Dog

Portrait - DanteDante is the newest addition to our team. He is certified by Therapy Dogs International and works as Margaret’s assistant. There is plenty of evidence on pet-assisted therapy now, and with Dante we see it every day: reluctant children blossom, fidgety children calm down, and those who stutter speak more easily. A number of children who were previously afraid of dogs, have warmed up quickly to his calm, gentle personality–it probably also helps that he’s less than a foot tall and weighs 10 pounds. He’s always happy to greet everyone and enjoys a scratch under his chin. His only bad habit–as one little girl aptly described…”he’s a licker!” We’ve found he especially enjoys bare toes.


Our primary goal in therapy is to provide support for families in their efforts to communicate with their children. Since the home and community are where communication occurs, we believe our role is to provide strategies that parents can incorporate into typical family activities. We not only teach children, we help families develop new skills and competencies as well.

We believe that communication and self-esteem develop together as a result of a child’s successful interactions with others. We know that our success in therapy depends upon the establishment of positive relationships with each child and family we serve. Our interactions with children depend upon mutual respect and trust; children come to view us as adult friends.

Purpose: We achieve our mission by:

  • Providing outstanding services to children with communication needs
  • Serving as a resource and offering support to families
  • Providing regular outreach to the community
  • Offering a nurturing, stimulating and rewarding environment for all


We have been leaders in this community for 40 years. The practice was begun in 1976 by Karen D. Culhane, MS in Arcadia. In 1988 Margaret H. Briggs, PhD assumed ownership and two years later moved the practice to Pasadena.

We believe our logo clearly represents our philosophy and purpose. It was inspired by the paper dolls Margaret’s grandmother used to make for her when she was growing up in New York. The children holding hands remind us to go out in the world together: supporting and learning from each other. The balloons evoke an image of hope—rising above and flying higher. Many years ago Margaret stitched this quote (you’ll see it hanging in her office now) that embodies our beliefs and values:

“To laugh often and love much;
To win the respect of intelligent persons
and the affection of children;
To earn the approbation of honest critics
and to endure the betrayal of false friends;
To appreciate beauty;
To find the best in others;
To give of one’s self,
To leave the world a bit better,
whether by a healthy child, a garden patch,
or a redeemed social condition;
To have played and laughed with enthusiasm
and sung with exultation;
To know that even one life has breathed easier
because you have lived—
This is to have succeeded.”

– Ralph Waldo Emerson
