ADHD therapists and psychiatrists in Newark, DE

Hi, my name is Dr. Lynn Rosenthal. I have many decades of experience helping people with issues presented. I have two Masters degrees and one doctorate in psychology. My experience varies assisting many with different issues within individual, couples, and marital counseling. I also provide clinical supervision and I am a Board Certified Executive Coach. I have afternoon and evening appointment available.

Life has taught me so much. After the school of hard knocks I decided to go to a real college and found that I was not only bright but I had a real talent for helping people. I completed my Ph.D. in clinical psychology specializing in neuropsychological assessments. I was lucky enough to complete a residency at the A. I Dupont Children's hospital. I have also worked with crises units, residential teen facilities, developmental clinics and the division of prevention and behavioral health through the state. I opened my own private practice in January 1999 where i specialized in therapy for children, teens and adults. Now after retiring with 20 years from the state, I am more relaxed and less pressured. I take my time with people, listen to their needs and work with them to help find solutions.

I am a licensed Professional Counselor with over 30 years of experience working with diverse populations: Children, adolescents, adults, couples, and families. I have worked in various treatment settings: residential treatment, day treatment, foster care, agency, school (elementary, middle and high school), and private practice. I treat depression, anxiety, trauma, adolescent issues, family therapy, loss and grief, school issues, attachment, EAP/work-related issues. I am trained in PCIT.

My specialties include: adolescents, anxiety, depression, loss and grief, trauma, school and work-related issues.

A client will feel respected and nurtured from the moment that client walks into the practice. The atmosphere is peaceful and relaxing and conducive to working through issues and beginning the journey to a new you.

I have over 20 years of experience providing psychotherapy across a wide range of settings, including acute and non-acute mental health, residential treatment, and outpatient care. Throughout my career, I've worked with adults, adolescents, individuals, and couples facing everything from everyday life stressors to more complex emotional and psychological challenges.

While I work with a broad range of concerns, I have particular interests in relationship counseling using the Gottman Method, chronic pain utilizing Pain Reprocessing Therapy (PRT), addiction, borderline personality disorder using DBT, and anxiety-related disorders. I also frequently help clients navigate life transitions, relationship difficulties, parenting, work stress, panic, and general emotional well-being.

One thing that deeply shapes my work is a genuine curiosity about the human condition. I believe every person's story makes sense when we take the time to understand it. Rather than viewing people through the lens of a diagnosis alone, I strive to understand the experiences, relationships, beliefs, and circumstances that have shaped who they are. I see therapy as a collaborative process of exploration, insight, and meaningful change.

Over twenty years of experience providing mental health services to a wide range of clients - finding the unique nature of each individual.

I believe that healing happens best in a space that feels both professional and human. With over a decade of experience supporting vulnerable children, families, and adults, I’ve dedicated my career to helping people navigate their most challenging seasons—specializing in substance use recovery and child and adolescent mental health.

My background is rooted in a BA in Psychology from the University of Delaware and an MSW from West Chester University. While my training prepared me to navigate complex medical and educational systems like school IEP/504 meetings, disciplinary boards, hospital teams, and the foster care system, my real-world experience has taught me that every individual and family needs a unique, compassionate approach.

I’m a firm believer that the world needs more laughter, and that therapy doesn't always have to feel heavy. When I’m not in the office, I’m usually painting or glued to a good book. I believe that therapy, much like art, is a process of creation and discovery, and I’d be honored to walk that path with you.

Back-to-school ADHD & adolescent anxiety visits — evening appointments available! If you've cycled through medications that didn't work, been put on prescriptions that never quite fit, or felt handed a pill for every symptom without anyone explaining why — you're not a difficult case. You're a patient who hasn't been fully heard yet.

I'm a board-certified Psychiatric Mental Health Nurse Practitioner with additional certification in telebehavioral health, and I do things differently: I take the time to get the complete picture before making any decision. My career — from flight nursing to inpatient behavioral health — taught me to stay calm and thorough with the most complex cases. I treat mental and physical health together,

grounded in evidence-based care, and I make sure you understand your options — medications, nutrition, sleep, movement — so you can make real choices about your own care.
