Sometimes life feels heavy, confusing, or just… too much. You might be dealing with stress, anxiety, relationship struggles, parenting challenges, grief, childhood trauma, or big life changes. Feeling stuck or unsure of what to do next is normal, and you don’t have to face it alone. In therapy, you’ll find a caring, non-judgmental space to explore what’s on your mind, understand your feelings, and take gentle steps toward feeling more balanced, confident, and at peace with yourself.

I offer a safe, caring space where you can share what’s on your mind without judgment. Together, we explore challenges like stress, anxiety, relationship struggles, grief, childhood trauma, or big life changes. My approach is collaborative and tailored to you, helping you understand your feelings, develop coping skills, and take gentle steps toward healing and growth. Whether you want to build confidence, process difficult experiences, or simply feel more balanced, I’m here to walk alongside you, one step at a time.

As you work through therapy, you may start to notice subtle but meaningful changes in your daily life and overall well-being. These can include a greater sense of calm and emotional balance, increased self-awareness and understanding of your thoughts and feelings, healthier ways of coping with stress, anxiety, or past trauma, stronger, more fulfilling relationships, greater confidence and self-compassion, and a clearer sense of direction and empowerment in your life

Growth often happens gradually, but even small shifts can create a ripple effect, helping you feel more resilient, peaceful, and in control of your journey.

More than just my work:

I was fortunate to grow up in an open and equitable environment that inspired individuality while providing the protection and sense of security of a collective environment. This helped me relate to Herman Hesse’s saying, “Within you, there is a stillness and a sanctuary to which you can retreat at any time and be yourself.” Varied dance forms and music from around the world have attracted me since a young agebringing me peace and joy. I also love cookingyoga and meditation. These are aspects of my inner sanctuary.  

Answers to some frequently asked questions:

Deep Brain Reorienting (DBR) is a trauma therapy that helps the brain process experiences that were overwhelming or shocking. It focuses on the body’s very first automatic reaction to a stressful event, before emotions like fear or shame appear. With gentle guidance, clients notice subtle bodily sensations, allowing the nervous system to complete a response that may have been interrupted during the trauma.

As this process unfolds, trauma memories may feel less emotionally charged, people may experience less hypervigilance, improved nervous system regulation, and deeper processing of early childhood trauma.

EMDR (Eye Movement Desensitization and Reprocessing) and DBR (Deep Brain Reorienting) are both trauma therapies, but they work at very different levels. EMDR is memory-focused and uses bilateral stimulation – such as eye movements or taps – while the client recalls a traumatic event, helping the brain reprocess the memory and reduce its emotional intensity. It follows a structured 8-phase protocol and is most effective for processing specific traumatic memories. In contrast, DBR targets the earliest physiological responses to trauma, often stored in the brainstem and limbic system, including pre-verbal or developmental trauma. Rather than focusing on conscious memory, DBR guides clients to attend to subtle bodily sensations and internal orientations, allowing the nervous system to complete unresolved trauma responses. While EMDR is highly structured and cognitive-emotional, DBR is more somatic, body-based, and focused on deep, often unconscious processing, making it particularly useful for complex or early-life trauma.

Somatic therapy recognizes that trauma is stored in the body, not just the mind. Somatic Experiencing helps you tune into your body’s sensations, release stored trauma, and regulate your nervous system. This approach is especially helpful when talk therapy alone hasn’t been enough.

Somatic therapy helps people heal trauma by paying attention to body sensations and how the nervous system responds to stress. Trauma can leave the body stuck in survival states like fight, flight, or freeze. In therapy, we slowly notice physical sensations, breathing, tension, and movement so the body can safely release stored stress and complete responses that were interrupted during the traumatic event.

As the nervous system settles, people often notice that trauma memories feel less overwhelming, their body feels calmer, and they have a greater sense of safety and regulation.

In traditional talk therapy, the focus is mainly on talking about experiences, thoughts, and emotions. Understanding what happened and how it affects you can help create insight and new ways of thinking.

Somatic therapy also values conversation, but it places more attention on what is happening in the body and nervous system. Trauma and stress can leave the body stuck in survival responses such as tension, hypervigilance, or shutdown. In somatic therapy, we slow down and notice body sensations, breathing, and physical responses so the nervous system can gradually release stored stress.

Rather than only understanding the trauma, somatic therapy helps the body feel safer and more regulated, which can make trauma memories feel less overwhelming over time.

Absolutely. I specialize in complex PTSD and dissociative disorders including depersonalization, derealization, and dissociative amnesia. I use specialized approaches like EMDR, DBR, somatic therapy, and parts work to help you safely process trauma and reduce dissociative symptoms.

Yes. I offer therapy sessions in English, Bengali and Hindi for clients in Mississauga and across Ontario. Working in your first language can make it easier to express complex emotions, process traumatic experiences, and feel fully understood.
