Get to know me

In our first session together, here's what you can expect

In our first session together, we'll start with identifying symptoms and how they are affecting your overall functioning. We'll also go over your medical and psychiatric history, and current and past medication trials. This will help me create a tailored plan for us to work through in follow-up sessions. ***NOTE: Due to DEA restrictions, I am unable to prescribe controlled substances in Illinois and Kentucky.

The biggest strengths that I bring into our sessions

My biggest strengths are listening to each client and taking all areas of their life into consideration when developing a treatment plan. It's important to recommend a treatment plan that the client is a part of and willing to participate in.

The clients I'm best positioned to serve

I love working with professionals who are struggling with increased stressors that are affecting their day-to-day functioning. My clients often feel stuck, overwhelmed and anxious. ***NOTE: Due to DEA restrictions, I am unable to prescribe controlled substances in Illinois and Kentucky.

Fantastic first visit. I was very nervous and Dr Mueller put me at ease quickly. She was a great listener. She explained things well. So far I'm very pleased.

I sought therapy as I have been struggling with anxiety and anticipatory grief. Denayer has been one of the few bright spots on this new journey I find myself embarking on.
