10 Things to Know About Jessica Oppenheimer, LCSW

1. Why did you choose to become a therapist?

It honestly felt natural. I have always been a people person and a caretaker (so I’ve been told). As I got older and this began to apply in more formal settings, I began to experience success and gratification from these encounters. Becoming a therapist just fit.

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

Being a part of someone’s change process. As many of my clients know, I love to reflect on “where you started vs. where you are now,” even if it’s just to highlight a very small shift or improvement. The change process is challenging and can be scary. Supporting and guiding someone through that and helping them to see the outcome of their efforts, is the best part of the job for me.

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

To have hope and stay curious. This was instilled in me by my very first supervisor as a social work intern.

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

Hmm, this is a tough one. Probably working in HR or some other related field where my role would be to support others.

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

Spend time with friends, enjoy good food, and treat myself to the occasional massage.

6.  What’s your favorite quote or mantra? 

“Be the change you wish to see in the world.” —Gandhi

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

Practice the DBT radical acceptance skill! It can be the most difficult AND the most helpful skill throughout life.

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

RBG, Adam Sandler, and Michelle Obama

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

My relationships with family and friends.

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

It’s ok to not be ok.
