Meet Prime Spark Founder

Sara B. Hart, Ph.D.


The Second Women’s Revolution is here.
(Started by a woman who helped drive the first one.)

 We are on the cusp of a major social change.  Can you feel it?   If not, make no mistake.  It is about to come on the scene and be unforgettable.

We are about to see the ascendency of older women, women over 55.  In droves, we will be standing up and saying, “It’s time for a change.”

It may feel like a revolution.  Or a transformation.  Or even at times like a quiet, but steady and unrelenting change to the way things have been.  The status quo has met its last hurrah.

As Gloria Steinem said, “One day an army of gray-haired women may quietly take over the Earth.”

For some women, it will feel like a ‘taking over of the earth.’  But for others, it will be a quiet putting done the chains of what was and has been and picking up a ‘let’s do this’ attitude as their call to arms.  A call to begin … or to continue … making a significant contribution to some of the gnarly problems that are facing us at the present time.

Because it is time.

It is time for us to find that spark that will ignite our way forward, illuminating our path and reflecting our gifts in the world.  This is the spark in the prime of our lives.  This is our Prime Spark.


 What’s Your Prime Spark?


If you’re a woman who is at least 55 years old, chances are you’ve enjoyed your share of successes as a mother, a business woman, or other type of professional. 

As you celebrate your accomplishments, however, that sense of satisfaction often comes with an uneasy feeling of “what’s next?” After gaining a lifetime of skills and experience helping others, it sometimes happens that you lose a little confidence as you contemplate making new life choices—this is partly because the workforce and media culture send messages often biased against senior women. This must change.

That’s why I created Prime Spark.
Prime Spark is for senior women who want to thrive, make the best choices for their prime years, and fight how our culture tries to depict us. I encourage you to ignite your Prime Spark.” —Sara B. Hart



 “It is time for us to fuel that Spark that will ignite our way forward, illuminate our path and reflect our gifts in the world. This is our Prime Spark for living a fulfilling life.” 

—Sara B. Hart
