Hi! I'm a Licensed Clinical Professional Counselor (LCPC) in Maryland, a Licensed Professional Counselor (LPC) in Virginia and a Licensed Mental Health Counselor (LMHC) in Florida. I received a Doctorate in Behavioral Health from Arizona State University. I have over 15 years of experiencing providing therapy to others. I have worked with different populations in a number of setting including schools, home-based, a maximum-security prison, and outpatient mental health clinics.
In our first session together, I will learn more about you, your history, and the specific challenges that you want to address. We will work together collaboratively to identify your therapy goals. We will work to achieve those goals in our follow up sessions.
My philosophy in life is to treat others the way that I want to be treated. This philosophy also drives my approach to treatment. Every client is treated with respect, care, understanding, support, and without judgement. I want to help you on your journey to health and wellness.
I believe that therapy is a collaborative effort. I work best with clients that are motivated to change and committed to the process. We will work together to increase insight, make behavioral changes, resolve issues, and achieve your goals.

I’ve tried therapy a few times and this is the first time it’s felt right. I’m optimistic about my journey with Dr. Cullum and I appreciate how affirming and genuine she is.

Dr. Cullum, creates an immediately safe and welcoming space. She listens with genuine attentiveness, not just to respond but to truly understand. Her presence is warm, grounding, and inviting, which makes it easy to open up without feeling rushed or judged. I felt seen and respected!
