ADHD therapists and psychiatrists in Williamsburg, VA

​I am experienced in treating PPD/PPA, pregnancy loss, birth trauma, and related concerns. I am trained in EMDR with a focus on the perinatal period. I enjoy working with parents to support positive attachments with their children, navigate through challenges, and understand developmental stages and concerns.

I also work with those experiencing difficulties related to ADHD, life transitions, anxiety, depression, and trauma.

I’m Dr. Sharline Mashack, a board-certified Psychiatric/Mental Health Nurse Practitioner, and I specialize in treating patients with conditions ranging from ADHD to schizophrenia. I use a holistic approach combined with evidence-based practices to develop treatment plans, prescribe medications, and provide psychotherapy.

As a military spouse, I’ve had the opportunity to work in several areas of the healthcare system, learning from experienced leaders along the way. I earned both my Master’s and Doctorate in Nursing.

I am originally from North Carolina and moved to Virginia 6 years ago. I studied at Wake Forest University. Since I was younger, I've enjoyed helping others and learning about the science of mental health. It became my hobby when I was younger. I enjoy working with so many backgrounds and increasing my education each year as I help new people. Currently, I like to utilize mindfulness based CBT, DBT, and ACT.

I am a board certified psychiatric nurse practitioner for over 5 years, and I am also a board certified adult nurse practitioner for over 12 years. I began my nursing career graduating from university of MD with my bachelors, and then attended Johns Hopkins University for my masters. I decided to further my education by attending Brandman University to obtain my Doctorate and psychiatric mental health certification in 2018.

I’m a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with a Doctor of Nursing Practice (DNP) from Emory University. I bring over 8 years of clinical experience, including 4 years in medical nursing and 4 years in mental health care across inpatient, emergency, and outpatient settings.I also served as a nurse in the U.S. military, where I cared for active-duty service members, veterans, and their families. This experience shaped a steady, grounded approach to care, especially in moments of stress, transition, or uncertainty.

Life can feel overwhelming when anxiety, ADHD, depression, or family challenges start to take over. You may find yourself stuck in unhelpful patterns or unsure how to move forward. Therapy offers a space to slow down, sort through what’s happening, and discover practical tools for lasting change. Together, we’ll focus on building emotional resilience, improving relationships, and helping you feel more confident and in control of your life.

I'm April — a Licensed Clinical Social Worker who has worked alongside people in some of the hardest chapters of their lives: crisis moments in emergency settings, school hallways with overwhelmed teenagers, and outpatient rooms where families were trying to figure out how to be in the same room again. That range of experience has shaped how I work. I know that anxiety looks different in a 15-year-old than it does in a 40-year-old. I know that couples who love each other can still feel like strangers. And I know that healing isn't linear — it takes time, trust, and the right support.

I specialize in anxiety, depression, trauma, relationship and marital concerns, family conflict, parenting challenges, life transitions, and emotional regulation. I work with children, teens, adults, couples, and families. For clients who want it, I also offer faith-integrated counseling that weaves Christian beliefs and values into the therapeutic process — thoughtfully, ethically, and at your pace.

I am a Licensed Certified Social Worker-Clinical. I specialize in treating depression, anxiety, ADHD, PTSD, and complex trauma. I keep a warm, empathetic space where clients explore how thoughts and past experiences impact their mood and overall well-being. I genuinely value connection and collaboration in the therapeutic relationship.
