ABOUT
Hi, I’m Dr. Jenna Hennessy.
A licensed clinical psychologist and the founder of Maison Mind Psychology Studio. I work with people making sense of difficult emotions, relationships, and transitions in their lives.
Many of my clients describe feeling stuck, caught between wanting to move forward and not quite knowing how. My goal is to create a space where you can slow down, feel understood, and start to reconnect with what truly matters to you.
Over the years, I’ve helped people navigate anxiety, depression, relationship and family stress, perfectionism, OCD, grief, trauma, and the tough life transitions that can shake your sense of direction or confidence.
Our work isn’t just about talking. It’s about learning how to navigate the moments when your mind won’t stop racing, when you wake up in the middle of the night in a sweat, or when you find yourself back in familiar patterns you’re ready to change.
You’ll leave sessions with practical tools you can use right when you need them, to calm your body, shift your thoughts, and respond to stress in ways that align with your values. You don’t have to carry it alone.
Licensed in NJ, NY, and participating PSYPACT states
