We all seek connection with our significant other, yet many couples find themselves stuck in cycles that wear away at that connection. Frequent misunderstandings, arguments without resolution, lack of intimacy, broken trust, and life stressors can cloud feelings of love with anger, resentment, anxiety, and sadness. Sometimes even the most committed relationships need support to revive faded connections. My intention is to help you explore, clarify, and process what is truly going on between you. What are your needs, values, and desires? What patterns do you find yourself stuck in, and how did you get there in the first place?
I will cultivate a space where you can build understanding and empathy through honest communication. When couples can begin to slow down, speak openly, and listen with compassion, new possibilities emerge. There will be moments of tension and vulnerability in our sessions, but meaningful change often requires discomfort.
It takes courage to invite someone into your relationship. With curiosity, humor, and acceptance, I'll guide you to each other again.

I have training in EFT and the Gottman Method for couples. In our sessions, we explore what it means to feel connected, identify ways to enhance communication and closeness, and build awareness about emotions and the deeper meanings behind these emotions. It's not really just about the dishes, finances, or desire discrepancy. What do these conflicts say about your relationship?
