“I’ve always done virtual sessions with Derek, and they’ve always been great. Coming up on a year with sessions every two or three weeks. For the first time in 20+ of struggling with depression, addiction, and undiagnosed behavior disorders I feel like I am on top of things and am starting take more and more control of my life. Derek balances a personal, thoughtful approach with a profound understanding of the role and impact of the medications he prescribes (or doesn’t). I think the biggest way Derek has helped me to grow is how he gently pushes back whenever I begin to talk in absolutes- “I’m always…” or “My wife never…”, or even “I can’t…”. He highlights where the limits are and helps me to take notice of the times when things I feel like are absolute, are in fact not.”

“Derek's focus is always what is happening with the patient - are they eating, sleeping? Ears wide open, he listens to the challenges the patient is facing, and talk through a plan to get through those that are comfortable for the patient. Providing back and forth feedback to support the patient in being ready for their daily lives. I have been seeing Derek since my husband passed away 6 years ago. My father just passed away. His empathy and encouragement helps me navigate what I am going through, feelings, and action plans for reaching an outcome that is important to me.”

Getting to know Derek Walcker

My name is Derek Walcker and I am a Psychiatric Mental Health Nurse Practitioner (PMHNP) who resides near Howard County, and provides comprehensive, evidence based behavioral healthcare to all the residents of my home state, Maryland. Via telehealth, I am presently focusing on treating adults of all ages (18-senior) who are afflicted with any behavioral health condition (stress, anxiety, depression, ADHD, OCD, Bipolar, Insomnia, etc.) and I use a combination of both medication and psychotherapy to provide speedy remission of symptoms, while creating a long-term psychotherapeutic treatment plan to provide sustained relief.

What should a new client know about working with you?

As every patient is unique, I am steadfast in tailoring an individual treatment plan for each patient with their participation. I emphasize educating the patient of their diagnosis and treatment options, which can include psychopharmacologic agents, in addition to knowledge of how these medications function, effect the brain, possible side effects, and timeframe of symptom remission. I also employ psychotherapy to target cognitive distortions, dysregulated emotions, dysfunctional behaviors, and poor stress management, to help the patient develop the cognitive skills necessary to create a sustained egosyntonic state and prevent symptom relapse. This approach allows the patient and I to address both their short- and long-term needs, while providing a path that allows them to reach their full potential in all areas of their life.

Derek is great! In addition to his clinical acuity and responsiveness, he is also very insightful and action-oriented. He remains up-to-date on evidence based practice research and also has a fantastic sense of humor! I highly recommend him to anyone who is serious about integrated health and wellness.

Derek has a welcoming and approachable way about him. He takes his time and listens to me to personalize my treatment. He also has a lot of experience which makes me feel confident in his care. The practice is small and very responsive to my calls and texts for anything I need. I highly recommend Derek for medication management and therapy.
