Struggling in your relationship? Whether you're facing communication issues, rebuilding trust after infidelity, intimacy challenges, recurring conflicts, financial disagreements, parenting struggles, life transitions, relationship doubts, or navigating a divorce, we’re here to help. Our structured, results-driven couples therapy begins with weekly sessions, transitioning to biweekly, then monthly. After your "graduation," we provide two annual check-ins to reinforce progress. Between sessions, you'll receive customized tasks and ongoing support outside of appointments.
My approach is holistic and multicultural. After all, I have lived in multiple countries. Before your first session, we will have a complimentary brief phone call. During this call, we will discuss the reasons that led you to seek therapy. We offer both in-person and virtual therapy to accommodate your needs and preferences in multiple locations.
Come alone or with your partner. Reduce stress, defuse anger and resentment, navigate conflict with less drama, improve your sex life, and find work-life balance. Take the first step on your path to healing. As the saying goes, “A journey of a thousand miles begins with a single step.” Start by texting us today, and remember to stay true to yourself—Be You!

Living in various countries throughout my journey, I have had the opportunity to interact with a diversity of people and learned about their cultural backgrounds. This broad perspective allows me to "see" things with a more open mind, navigate and find solutions when it appears there isn't one!

Couples usually seek out therapy due to communication issues, infidelity, parenting conflict, problems with in-laws, financial issues, health problems, and life transitions such a divorce or grief. Initially, we start meeting 1/week to establish a strong foundation. As progress is made, we will transition to biweekly meetings, and ultimately, we aim to reduce sessions to once a month.

Before your 1st session, we will have a brief complimentary phone call. During this call, we will discuss the reasons that led you to seek therapy. By gaining a deeper understanding of your unique challenges, concerns, and goals, we will be able to work together to determine the most suitable approach. One size does not fit all. Therefore, we will not limit ourselves to a single treatment option.
