10 Things to Know About Oona Caplan, LCSW-R

1. Why did you choose to become a therapist?

I chose to become a therapist to effect change in others. It’s important that everyone understands there is always an opportunity to break learned patterns of behavior from our early childhood. And with the right kind of assistance, we can seek answers within ourselves and others, allowing us to embark on a journey to better ourselves.

2.  What’s your favorite thing about being a therapist?

Believing that anyone can and will be empowered to find ways to mend old wounds, learn new ways of dealing with stressors and emerging a stronger, more confident & kinder individual.

3.  What is your general philosophy and approach to helping?

I espouse the view, as John Bowlby stated: “The human psyche, like human bones, is strongly inclined towards self-healing.” I believe that therapy (a secure base) can help anyone overcome obstacles in life. We are not held back by our past and can change our current and future states.

4.  If you weren’t a therapist, what would you be doing instead, or what would your life be like?

If I had not become a therapist, I would have wanted to become a Veterinarian. I love animals and have dedicated much of my time (both as a teenager and now as an adult) to dog rescue. As a child, I spent time at my extended family’s farm in Ireland and believe that rural life, surrounded by animals, would have combined my passions of animals, medicine, and caring for others.

5.  What do you do as self-care? (Mindfulness practices, exercise, etc.)

I have always run as self-care. I was part of my high school’s track team and continue to run today. Running helps ground me after a stressful day by allowing me to focus on my breathing. I can appreciate my surroundings and engage all my senses as I run. It can be a reminder of the hurdles I have overcome and helps to focus on those in front of me.

6.  What’s your favorite quote or mantra? 

“Fear is inevitable, I have to accept that, but I cannot allow it to paralyze me.” — Isabel Allende

7.  What advice would you give your 16-year-old self?

I would tell myself, “things are never as daunting as they seem. You have so much to look forward to. Do not despair.”

8.  If you could invite three famous people to dinner, alive or dead, who would they be? 

I would invite Isabel Allende, St. Angela Merici, and Margaret Atwood

9.  What’s something you are most proud of? 

Creating and coaching the first track team for my children’s elementary school, and winning 3rd place in cross country during their first year of competing will always be one of my proudest moments!

10.  What do you wish other people knew about mental health?

  • Mental health is not a stigma, it is not a “curse”, and there are many ways to deal with it.
  • We are improving daily on ways to tackle different issues: from new medications to new therapeutic interventions.
  • I believe that finding a professional you connect well with will ensure your best outcome. Open communication is key.
  • Knowing that, even during what may feel to be the worst of days, you have an ally. Solutions for a positive outcome are just around the corner.
  • Finding the right “answers” can take time. Patience is also important which is why trust in your provider/team is imperative.
