Dorota Ketch is a Board-Certified Psychiatric Mental Health Nurse Practitioner (CRNP, PMHNP-BC) who is passionate about helping children, adolescents, and adults improve their mental health and overall quality of life. She believes that effective psychiatric care begins with understanding the whole person—not just a diagnosis, medication list, or set of symptoms.

Dorota earned her Master of Science in Nursing with a specialization in Psychiatric Mental Health from Anderson University and is board-certified through the American Nurses Credentialing Center (ANCC). She also holds a Bachelor of Science in Nursing from Ohio University. Her educational and professional journey reflects a longstanding commitment to behavioral health and patient-centered care.

Before becoming a PMHNP, Dorota worked as a psychiatric nurse, Charge Nurse, and Nursing Supervisor at Horsham Clinic, where she gained extensive experience caring for individuals with complex mental health needs in an inpatient setting. She later joined Philadelphia Integrative Psychiatry as a Ketamine Nurse, specializing in ketamine-assisted therapy and Spravato® (esketamine) treatment for individuals living with treatment-resistant psychiatric conditions.

Today, Dorota provides psychiatric evaluations, medication management, and ongoing mental health care for children, adolescents, and adults. She has experience treating depression, anxiety disorders, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), attention-deficit/hyperactivity disorder (ADHD), bipolar disorder, autism spectrum disorder, and treatment-resistant mental health conditions. She is also trained in Transcranial Magnetic Stimulation (TMS) and has a special interest in interventional psychiatry.

What sets Dorota apart is her belief that mental health care should be personal, collaborative, and focused on understanding the individual behind the symptoms. She enjoys taking the time to learn about each patient's experiences, relationships, strengths, challenges, and goals. While medication can be an important part of treatment, she also values the therapeutic aspect of psychiatric care and strives to help patients better understand the underlying factors contributing to their challenges whenever possible.

Dorota believes some of the most meaningful progress occurs when patients feel heard, understood, and empowered to participate in their own care. Her goal is not simply to reduce symptoms, but to help patients gain insight, build resilience, strengthen relationships, and create lasting improvements in their overall well-being.

Dorota is licensed to provide psychiatric care in Pennsylvania and Delaware. She is also bilingual in English and Polish. Her diverse educational and professional background has shaped her holistic, compassionate, and individualized approach to mental health care.   Education:

Taneestar Cohen is a board-certified Psychiatric Mental Health Nurse Practitioner and Adult-Gerontology Primary Care Nurse Practitioner with over 20 years of nursing experience. She brings seasoned clinical judgment, thoughtful diagnostic insight, and a patient-centered approach to psychiatric care. 

Her professional background includes more than a decade in Sleep Medicine, where she developed a strong understanding of the connection between sleep, mood regulation, cognitive functioning, and overall psychiatric stability. This experience strengthened her ability to recognize clinical patterns that often contribute to complex or overlapping symptom presentations. 

Taneestar earned her Post-Graduate Certification as a Psychiatric Mental Health Nurse Practitioner from Wilkes University and holds Adult-Gerontology Primary Care Nurse Practitioner certification from Wilmington University, where she graduated with Honors and was inducted into the Sigma Theta Tau International Honor Society of Nursing. 

Her clinical practice is grounded in evidence-based psychopharmacology, careful differential diagnosis, and individualized treatment planning. She takes an integrative approach, considering biological, psychological, and environmental factors when developing comprehensive care strategies tailored to each patient. 

She treats a range of conditions across the adult lifespan, including depression, ADHD, mood disorders, premenstrual dysphoric disorder (PMDD), generalized anxiety disorder, social anxiety disorder, trauma-related conditions, and sleep disturbances. In addition to symptom reduction, she prioritizes functional restoration, emotional regulation, cognitive clarity, and long-term stability. 

Known for her attentive listening style and balanced approach to medication management, Taneestar strives to create a safe and respectful environment where patients feel heard, understood, and actively involved in their care.

My core approach to care begins with the unique story each patient needs to tell. When you arrive there is a comfortable waiting room with plants and music playing. Treatment with me is based on a collaborative effort between me and my patients. I begin each relationship with a comprehensive two hour psychiatric evaluation, that includes a full medical history as well. I also focus on the importance of nutrition and healthy eating during that evaluation. At the end of the consultation, there is open discussion about treatment options. If a patient has an existing therapist, a release form is signed so there can be ongoing confidential communication between providers. At all times patient confidentiality is held sacred and absolutely necessary for successful treatment. During my time in practice I have always been a staunch advocate for my patients, particularly in the area of insurance denials. I am equally passionate about patient education.
