Roni Rubins


Children 5+

The author Diane Chamberlain said: “Every family has a story, and I love that those stories are etched in the sand rather than granite. That way we can change them.” Every family, couple, or individual has their own unique story. I believe that my therapeutic responsibility is to create a supportive environment that allows clients to explore their experiences and together, create the changes you want to see in your story.
