For as long as I can remember, I’ve been drawn to the deeper questions—what shapes us, how we connect, and why healing is so hard and so important. That curiosity became a calling, and now I help individuals and couples across California do the work of healing, growth, and reconnection.

Whether I’m walking with someone through relationship pain, faith deconstruction, or the aftermath of betrayal, I bring a blend of clinical skill, personal honesty, and spiritual depth. Here’s a bit more about my background, training, and what led me to this work.

  • My love for psychology started in high school and hasn’t let up since. For over 20 years, I’ve been fascinated by how people think, feel, connect, and make meaning—especially in their closest relationships.

    I earned my Master’s degree in Clinical Psychology from Azusa Pacific University, and I’ve worked in community mental health, private practice, and specialized clinics since 2007. I began my specialty in sex addiction and betrayal trauma in 2013, training under Dan Drake at, what is now, Banyan Therapy Group in Studio City, California.

    I’m trained in

    • Gottman Method Couples Therapy

    • Multidimensional Partner Trauma Model (APSATS)

    • Sex Addiction (IITAP)

    • Relational Life Therapy

    I bring in tools from

    • polyvagal theory

    • cognitive behavioral therapy (CBT)

    • dialectical behavior therapy (DBT)

    • acceptace and commitment therapy (ACT)

    • attachment theory

    • existential psychology

    I don’t offer quick fixes or bandaids. I help people navigate the messy, meaningful work of growth—with compassion and clarity.

  • I believe healthy families begin with healthy couples. And healthy marriages don’t just happen.

    Scripture says marriage is ‘two becoming one’—but that kind of unity isn’t automatic. It takes humility, honesty, and work. It requires each person to yield—to let go of ego, control, fear. Most of us resist that. Even when we want to change, we don’t always know how.

    That’s where I come in. I help you clarify your values, understand what’s in the way, and build the skills you need to create the marriage you want. It’s not about fixing your partner—it’s about growing the relationship.

    I won't ask you to be someone you're not. But I will challenge you to become more of who you're meant to be—in your marriage and in yourself.

  • I specialize in working with individuals and couples navigating:

    • Sex and porn addiction

    • Betrayal trauma and infidelity recovery

    • Communication breakdowns and unresolved conflict

    • Emotion regulation, stress, and spiritual struggle

    If you’re navigating any of these challenges, I offer a safe and structured space to heal, grow, and move forward—together. You are not alone, and you’re not beyond repair.

  • Outside of therapy, I’m usually at home in Southern California with my husband, our two boys, and our dog, Watson.

    I’ve been a Christian my whole life, even through seasons of doubt and deconstruction. I believe faith has to be questioned in order to be real. When I bring Scripture into sessions, it’s not to preach—it’s to invite curiosity. If you’re a fellow follower of Jesus, I’ll challenge you—and I welcome your challenge in return. Iron sharpens iron.

    I love analogies and metaphors and use them often: from sitcoms like The Office and Parks & Rec to epic stories like Star Wars or Lord of the Rings.

    Oh, and I’m a fan of coffee, gardening, and sneaking away to one of the local hot springs when I get the chance.

If you’re ready to stop spinning your wheels and start doing the real work, I’d love to walk with you.
