OCD Psychiatrists in Massachusetts

I specialize in family-centered care, working with individuals aged 18 to 65. Whether supporting patients through anxiety, depression, ADHD, or life transitions, I develop personalized diagnostic and treatment plans that may include therapy, coping strategies, and, when appropriate, medication. My approach emphasizes clear communication and collaboration, empowering patients to understand their challenges, apply practical tools, and achieve lasting change.

I have been a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) since 2015. I earned my advanced nursing degree with distinction from Arizona State University and also hold a Bachelor of Science in Nursing from Grand Canyon University and an Associate of Science in Nursing from Harry S. Truman College. Throughout my career, I have served as a Psychiatric Nurse Practitioner and Associate Director of Medical Services, leading multidisciplinary teams and promoting accessible, high-quality care. As a Faculty Associate at Arizona State University, I have mentored future nurse leaders, focusing on clinical excellence and patient advocacy.

My military background and volunteer work further reflect my commitment to serving diverse populations with compassion and respect.

My practice emphasizes Diagnostic Clarification, which is an ongoing process. I am highly trained and experienced in the biological and psychosocial underpinnings of psychiatric problems. I typically follow diagnostic evaluations with 30-minute follow up visits for medication adjustments and brief therapy, and I often enjoy collaborating with outside therapists when needed. My practice has always combined medications with evidence-based therapies to alleviate suffering and maximize functioning.

I am Board Certified in Adult Psychiatry and Addiction Medicine. I have practiced general psychiatry for 37 years and have also sub-specialized in Addiction Psychiatry for the past 20 years. I graduated from Amherst College and received my medical degree from NY Medical College. I subsequently completed my residency in psychiatry at the Mount Sinai Medical Center in NYC, where I excelled in Academic Psychiatry as both a teacher and a mentor.

In addition to my work as a Board Certified Adult Psychiatrist, I have specialized in helping patients suffering from Substance Use Disorders. I am Board Certified in Addiction Medicine and help patients understand the interrelationships between their Substance Use Disorders and their Psychiatric illnesses.

I am a board-certified Psychiatric-Mental Health Nurse Practitioner who provides mental health care using a personalized, holistic approach. I specialize in psychiatric evaluation and medication management along with psychotherapy and integrative interventions. I specialize in working with adults experiencing a wide range of acute and chronic stressors and mental health symptoms. I tailor treatment to the goals, needs, and comfort level of each individual at his or her own pace. I build connections with patients so that they feel heard and understood, and partner with each individual to determine the most appropriate treatment strategies that maximize comfort, safety, and positive results.

Prior to receiving education and training in Nursing at New York University and Case Western Reserve University, I earned a Master of Social Work from Boston College with a focus on health and mental health. Over the past ten years as a Nurse Practitioner in outpatient and inpatient environments, I have helped patients improve and overcome conditions including depression, anxiety, OCD, PTSD, ADHD, and insomnia. Using a combination of medication management, individual therapy, and psychoeducation, I develop individualized treatment plans centered around patients' priorities and safety to achieve improvements in health and quality of life.

In addition to medication management, I augment my practice by implementing mindfulness, psychodynamic, and supportive therapy techniques to enhance treatment and improve treatment response. My clinical experience has spanned the inpatient and outpatient settings, affording me the opportunity to develop comprehensive skills in the treatment of PTSD, mood disorders, thought disorders, addiction, and perinatal mood disorders.

I have also delivered presentations at national and international conferences on various topics, reinforcing my commitment to advancing the field of psychiatry.

My primary focus is holistic care, taking into consideration all physical, psychological, interpersonal, and environmental factors when creating unique treatment plans. I strongly believe that all of these factors are interconnected and play a significant role in any individual's mental health and vitality. My goal is to work with clients to create a safe, non-judgmental, and collaborative treatment environment that promotes sustained healing and positive self-development. My practice focuses on medication management. Occasionally, I may believe that additional therapy is also needed and ask that you bring a therapist into your care team to provide the best outcome.

I am a board-certified psychiatric nurse practitioner. My academic journey began with a B.S. in Biology from the University at Albany. I later received my B.S. in Nursing from Pace University and attained my Psychiatric Mental Health Nurse Practitioner M.S. from Hunter-Bellevue School of Nursing, graduating magna cum laude. For the last seven years, I have diligently provided care to our nation's veterans, working on a dual diagnosis inpatient psychiatric unit in the VA New York Harbor Healthcare System. In my time at the VA, I have gained extensive experience in managing substance abuse and co-morbid psychiatric disorders. In addition, while attending Hunter College, I completed a yearlong clinical rotation at Casa Promesa, a mental health outpatient and inpatient facility that services some of the most vulnerable and underserved populations in the South Bronx.

Dr. Deringer is a psychiatrist with board certification in general psychiatry and addiction psychiatry. She earned her M.D. from the University of Michigan Medical School, and she completed her psychiatry residency and addiction psychiatry fellowship training at New York University. She has previously held faculty roles at New York University School of Medicine and Harvard Medical School. She has been involved in training the next generation of psychiatrists through her past work on the Program Director team for the MGH-McLean Psychiatry Residency Program. She has expertise in treating adults with mood disorders, anxiety disorders, substance use disorders, personality disorders, trauma, and ADHD.

Dr. Deringer cares deeply about understanding each patient's unique experience.  She recognizes that mental health symptoms are impacted by an individual's biological make-up, social situation, and their individual way of interacting with others in the world.  She will assess all of these factors and work with you to develop an appropriate treatment plan to help you feel better and meet your goals.  She incorporates supportive psychotherapy into all of her patient meetings; this may include discussions of the role of nutrition, exercise, and sleep habits in your overall well-being.

Dr. Deringer will begin the evaluation process with a thorough one-hour session in which we will discuss your current symptoms, your prior treatment history, your medical history, and your goals for treatment.  At the end of that session, she will begin to formulate her diagnostic impression and treatment recommendations.  Sometimes, the evaluation process may require more than one session, and it may be helpful for Dr. Deringer to gather information, with your permission, from prior treatment or to collaborate with your therapist if you have one.  Dr. Deringer will work with you on a medication treatment plan, if clinically indicated, to help you manage your symptoms and achieve your treatment goals.

I take a holistic, collaborative, and non-judgmental approach to mental health care. I strongly believe that each person's struggle is unique, and that solutions and treatments should be individualized based on the person's goals. Having experienced childhood trauma myself, I am particularly passionate about and experienced in treating C-PTSD, OCD, ADHD, and borderline personality disorder. My focus is on helping others find peace, whether momentary or lasting, in their chaotic and often overwhelming lives.

I graduated from Boston College with my MSN after many years of working in inpatient psychiatry at McLean Hospital in Belmont, MA, and I have over a decade of experience in mental health care. I have worked in various outpatient settings, first in Boston and more recently in Las Vegas, gaining extensive experience with individuals from diverse socio-economic and cultural backgrounds.

The first appointment includes a comprehensive psychiatric evaluation and a discussion about your goals for treatment. While pharmacological treatment may be part of the plan, I prefer to focus on the therapeutic aspect of care, as I believe therapy is an essential component of healing. You can expect to collaboratively create a treatment plan that you feel comfortable with, rather than simply being told what to do.

I believe that addressing mental health is just as important as addressing physical health. My practice focuses on medication management, often combined with supportive or cognitive behavioral therapy, with an emphasis on integrating medication management with individual therapy to provide comprehensive, patient-centered care. I provide care for individuals with a wide range of mental health conditions, including depression, anxiety, substance use disorders, ADHD, bipolar disorder, OCD, schizoaffective disorder, and schizophrenia.

I take a collaborative approach to care, working closely with other mental health professionals, medical providers, families, and relevant support systems to ensure well-rounded treatment. I emphasize a patient-centered, individualized approach, combining medication management with psychotherapy to meet each person's unique needs. Patients working with me can expect a thorough evaluation, accurate diagnosis, and a personalized treatment plan tailored to their mental health goals. One of my core priorities is to empower individuals to make informed decisions about their care by providing education grounded in research, evidence-based practices, and clinical experience.

My philosophy includes a healing-oriented approach that considers the whole person, including all lifestyle aspects.

I am committed to providing compassionate, evidence-based care that considers the full spectrum of biological, psychological, and social factors. I build therapeutic relationships on empathy, respect, and trust. By tailoring treatment plans to each patient's personal and cultural context, I help individuals take control of their mental health and work toward long-term recovery and resilience. In the first session, I take time to listen carefully and gather a thorough understanding of each patient's concerns, history, and current functioning. I use empathy and active listening to foster open communication and develop personalized treatment plans that may include therapy, medication, or lifestyle changes, with the goal of restoring wellness and stability.

I earned my undergraduate degree in molecular genetics from the University of Vermont and conducted neuroscience research in both academic and industry settings. I am a graduate of St. George's University School of Medicine and completed my psychiatry residency at Mather Hospital, Northwell Health, where I was honored as Resident of the Year in 2025 and inducted into the Alpha Omega Alpha Honor Medical Society.

I utilize humanistic, person-centered, collaborative, strength-based, cognitive behavioral, mindfulness-based, solution-focused, and emotionally focused approaches to therapy while maintaining an open, flexible, creative atmosphere to remain aware of the unique and individual needs of each client. I seek to create a non-judgmental and safe environment where a caring relationship can be built with my clients to utilize and add to their strengths.

Together, we collaborate on a treatment plan that aligns with the patient's personal goals, ensuring care is both personalized and empowering. Patients working with me can expect compassion, respect, and a collaborative partnership in their care.
