Have you ever left a psychiatric appointment feeling rushed, unheard, or like you couldn't truly speak your mind? Finding the right mental health provider shouldn't feel like walking on eggshells, nor should it feel like your treatment is being dictated to you. If you are looking for a provider who actually listens, explains the "why" behind every decision, and treats you as an equal partner in your own care, you are in the right place. In my practice, there is no need to censor yourself. Come exactly as you are, speak how you want to speak, and let’s have real, honest conversations about what you’re going through. I provide a completely judgment-free zone where your lived experience is respected and valued.

What stands out about my medication approach: * I start low and increase gradually. * I regularly review for side effects.

First session

I do not believe in a "my way or the highway" approach to mental health. True healing happens when we collaborate. As a Board-Certified Psychiatric Mental Health Nurse Practitioner, my role is to bring clinical expertise to the table, while you bring the expertise of you. Together, we will build a treatment plan that aligns with your specific goals and lifestyle. I am committed to radical transparency. Whether we are discussing a thorough clinical assessment, a new diagnosis, or exploring medication management options, I will break down every detail in plain, easy-to-understand language. We will never move forward with a plan until all of your questions are answered and you feel completely comfortable with our next steps.

Strengths

Because I know mental health doesn't stick to a rigid schedule, I’ve designed my Massachusetts telehealth practice to be highly accessible and convenient for busy lives: * Flexible Scheduling: Appointments available Monday through Friday, 9:00 AM to 7:00 PM. *Unprecedented Access: My patients are never left in the dark. I guarantee 24/7 direct access to me via text and email between sessions for questions or concerns. *100% Telehealth: Care from the comfort and privacy of your own space, anywhere in Massachusetts. Taking the first step is often the hardest part, but you don't have to navigate this alone. Reach out today to schedule a free 15-minute consultation, and let's talk about how we can get you feeling like yourself again.

Ideal clients

Every mental-health provider brings a unique combination of experience, clinical insight, personality, and therapeutic style to their work. Over more than twenty years in behavioral health, I’ve learned that the strongest results happen when the right provider meets the right patient—someone whose needs, mindset, history, and goals align with that provider’s strengths. This profile will help you understand exactly who I am best equipped to help, so you can make a confident decision about your care. 1. Adults Seeking Clear, Structured, and Compassionate Guidance I specialize in working with adults who want a mental-health provider who is both clinically grounded and relatable. My style is calm, straightforward, and collaborative. If you value a provider who listens deeply, explains concepts clearly, and works with you—not above you—then my approach is likely a strong fit. Most of my patients appreciate clear direction, steady follow-up, and treatment plans that are realistic for their daily lives. If you’ve ever felt dismissed, rushed, or misunderstood in past treatment, you will find my care intentional, respectful, and centered around your real-world needs. 2. Individuals Struggling with Anxiety & Depression Many of the patients I serve experience: * Chronic worry or racing thoughts * Panic attacks or sudden spikes of fear * Excessive stress * Lack of motivation * Persistent sadness or emptiness * Feeling emotionally “stuck” * Loss of interest in things they used to enjoy These symptoms often affect work performance, relationships, sleep, and overall quality of life. My therapeutic approach blends practical tools with evidence-based medication management (when appropriate) to help patients regain stability, emotional balance, and a renewed sense of control. 3. Adults Trying to Manage ADHD or Executive Dysfunction A significant portion of my practice focuses on adults with ADHD—diagnosed, misdiagnosed, or never diagnosed at all. Many people come to me after years of: * Poor focus or distractibility * Procrastination * Disorganization * Difficulty starting or completing tasks * Time-management problems * Forgetfulness * Inconsistent performance despite strong abilities I help patients understand how ADHD affects their brain, relationships, and work—and together we build a plan using medication (if clinically appropriate), behavioral strategies, and practical tools that improve daily functioning. 4. Individuals Balancing High Stress, High Expectations, and High Responsibility I frequently work with people who carry a lot on their shoulders: professionals, caregivers, entrepreneurs, students, and individuals juggling multiple responsibilities. These clients often describe: * Feeling overwhelmed but unable to slow down * Perfectionism * Burnout * Feeling “on edge” * Difficulty relaxing * Trouble balancing life demands My style resonates with those who need structure, accountability, and straightforward communication without judgment. Together, we work to reduce pressure, build healthier coping strategies, and restore balance. 5. Clients Seeking Support for Trauma, Emotional Wounds, or Difficult Life Transitions While you do not need a formal trauma diagnosis to benefit from trauma-informed care, many of my patients have experienced: * Childhood emotional neglect * Difficult or unhealthy family dynamics * Relationship trauma * Grief or loss * Sudden life changes My approach emphasizes emotional safety, pacing, and a nonjudgmental environment where you maintain control over what you share and when. I help patients process the past while building tools to navigate the present more effectively. 6. Patients Who Want Treatment That Is Both Practical and Evidence-Based I am best suited for patients who want clarity, consistency, and actionable steps. My treatment plans are: * Personalized * Research-driven * Collaborative * Realistic and sustainable If you appreciate a provider who explains the “why” behind every decision and uses a blend of medication management and therapeutic techniques, you will find my approach empowering and easy to follow. 7. Adults Who Value Straightforward Communication and Honest Feedback Many patients seek me out because they want someone who will be: * Kind * Direct * Transparent * Engaged * Thoughtful, but never vague If you want a provider who is genuine, communicates clearly, and gives honest feedback while still being supportive, my style aligns well with those expectations. 8. Individuals New to Mental-Health Treatment or Returning After Previous Negative Experiences I often work with people who: * Have never seen a psychiatric provider * Tried therapy or medication in the past without success * Felt dismissed by previous clinicians * Were given a diagnosis that never fully fit * Want a fresh start with someone who will take the time to understand them My goal is to make your experience feel accessible, respectful, and empowering from day one. 9. Patients Who Want to Understand—Not Just Treat—their Symptoms I am best positioned to serve individuals who want to learn: * Why they feel the way they feel * How their symptoms developed * What strategies can improve their daily life * How medication works (or doesn’t) * What long-term stability looks like for them I emphasize education because understanding your mental health improves your ability to grow, heal, and make informed decisions. 10. People Who Appreciate a Provider Who Is Present, Reliable, and Consistent Consistency matters. Many of my patients stay with me because I: * Follow through * Check in regularly * Keep communication clear * Make thoughtful adjustments * Track progress over time * Care deeply about each client’s long-term outcomes If you value a provider who takes their role seriously and genuinely invests in your well-being, you will find a strong therapeutic fit here. In Summary: Who I’m the Right Fit For You’re likely a strong match for my practice if you are an adult who: * Wants structured, nonjudgmental, emotionally safe care * Struggles with anxiety, depression, ADHD, trauma, or mood instability * Needs both guidance and collaboration * Values clarity, transparency, and practical strategies * Wants treatment that blends therapy-informed tools with evidence-based medication * Is ready for meaningful, sustainable change—even if you’re unsure where to start If this sounds like you, you’re not alone—and you’re in the right place. I’m here to help you move forward with confidence, stability, and a treatment plan built specifically for your life.

Derek is personable and looks at the whole picture to address a solution that suits your needs. He consistently breaks down rating scales to assist in accurately addressing anxiety and depression levels while encouraging other supports such as talk therapy, etc. for the best possible health outcomes. He is easily accessible when medication issues arise with the pharmacy and we can't be more appreciative of that!

I am happy I took a big step towards reaching out to a new provider. The way someone is feeling is so important & when your voice is actually heard by someone. It can change anyone’s day making them have a positive outlook on their future & that’s so important. Thank you.
