Mariah Rideaux

Mariah offers attachment-focused therapy for adult individuals, couples, and families through Emotionally Focused Therapy (EFT) and EMDR, in person and via telehealth.

Licensed Marriage & Family Therapist (LMFT)

My work as a therapist is deeply rooted in what I’ve learned about attachment—both through my professional training and through my own life.

I’ve experienced the pain that can come from insecure relationships, as well as the safety, connection, and growth that can come from secure ones. Nothing has been more meaningful to me than not only studying attachment for over a decade, but also experiencing the transformation toward greater earned security.

That lived and learned experience shapes how I approach my work with clients through Emotionally Focused Therapy (EFT) and Eye Movement Desensitization and Reprocessing (EMDR). Building a strong, safe, and collaborative therapeutic relationship is at the core of my work with both clients and supervisees.

I believe you deserve a space where you can feel accepted as you are while also being supported to grow—a space where you can better understand how you show up in relationships and gently challenge yourself toward greater clarity, confidence, and security.

Together, we can create a consistent and grounded space to make sense of your experiences, understand the patterns that keep you feeling stuck, and find a path toward meaningful, lasting change.

Being human is messy. You don’t have to organize it alone. I’m here to help you hold it, make sense of it, and move through it with you.

I offer in-person and telehealth therapy for adult individuals, couples, and families.
