When anxiety, depression, trauma, or addiction start shaping your days, you need more than a listener — you need a therapist who can help you understand what is happening and show you a way forward.
If anxiety is always running in the background, depression has made everything feel heavy, trauma keeps resurfacing when you least expect it, or addiction has started taking up more space in your life than you want it to, knowing you need help is only the first step. The harder part is finding the right therapist. Hossein Kaji BSc, MA, MA, RP, PhD is a psychotherapist in Waterloo who brings together evidence-based counselling, calm clinical judgment, and an unusually thoughtful understanding of how people change. His background in counselling psychology and philosophy means you are not reduced to a label or a symptom list. You are met as a whole person whose thoughts, emotions, habits, relationships, values, and life experiences all matter. If you are searching for counselling in Waterloo, Hossein offers therapy that is grounded, practical, and deeply human. He helps you make sense of what is happening now, understand the patterns beneath it, and move toward meaningful change. Whether you are dealing with anxiety, depression, trauma, addiction, relationship strain, grief, or a life transition that has shaken your footing, the goal is not just short-term relief. It is to help you feel more steady, more clear, and more like yourself again.Hossein Kaji BSc, MA, MA, RP, PhD offers comprehensive psychotherapy with particular depth in the concerns that so often leave you feeling overwhelmed, disconnected, or stuck.
Hossein provides broad counselling, therapy, and psychotherapy support for adults, teens, couples, families, and older adults, so you do not need to fit into a narrow category to feel welcome in his practice. He works with a wide range of concerns within his scope, including stress, anxiety, depression, trauma responses, emotional dysregulation, relationship challenges, addiction-related struggles, and major life transitions. What makes him stand out is the way he blends structured, evidence-based methods such as CBT, DBT, MBCT, cognitive processing therapy, and solution-focused work with person-centred, existential, narrative, emotionally focused, family systems, and strength-based perspectives. That combination gives you more than technique alone. You get practical tools when you need direction, deeper reflection when life feels complicated, and a therapist who knows that real change often requires both. He also offers therapy in English and Farsi, which can make it easier to express the parts of your story that do not come out fully when you feel stressed or emotionally flooded.From your very first session, you can expect therapy that feels collaborative, thoughtful, and closely shaped around what will genuinely help you heal.
Hossein starts by understanding what is bringing you in right now, but he does not stop at the surface. He listens for the patterns underneath: how thoughts influence emotions, how emotions affect behaviour, how relationships shape stress, and how past experiences may still be affecting the present. That is what allows therapy to become more than a place to vent. It becomes a place to understand, practice, and change. Depending on what you need, he may draw from psychotherapy approaches such as cognitive behavioural therapy, mindfulness-based cognitive therapy, dialectical behaviour therapy, person-centred therapy, existential therapy, narrative therapy, emotionally focused therapy, family systems therapy, or trauma-informed care. At CARESPACE Weber North, that work can also be coordinated with other disciplines when a broader care plan would support your progress. You can expect clear communication, careful pacing, and a strong therapeutic relationship built on respect, honesty, and trust. Hossein’s aim is to help you feel heard without leaving you stuck in the same circles.His experience across hospital, community, and multidisciplinary settings means your care is guided by real-world clinical judgment, not theory alone.
Hossein is a Registered Psychotherapist with the College of Registered Psychotherapists of Ontario (CRPO #12109). He holds an MA in Counselling Psychology from Yorkville University, an MA in Philosophy from the University of Windsor, and a PhD in Philosophy from IRIP Institute. That blend of clinical and academic training matters because it allows him to be practical without being superficial, and reflective without losing sight of what actually helps you move forward. Professionally, he has provided assessment and therapy in hospital and community mental health settings, including work with St. Joseph’s Healthcare Hamilton, Compass Community Centers, Mind by Design, and other multidisciplinary environments where collaboration with psychologists, psychiatrists, and allied professionals is part of good care. His background includes individual and group therapy, CBT-based treatment planning, crisis situations, safety planning, high-risk assessment, adolescent and adult mental health support, PTSD care following motor vehicle accidents, and motivational interviewing for addiction-related concerns. That breadth matters because life is rarely simple, and your therapist should be prepared to meet complexity with steadiness, skill, and perspective.When anxiety, depression, trauma, or addiction keep pulling you back into the same painful patterns, this is where Hossein’s deeper expertise can make a real difference.
While Hossein provides comprehensive counselling and therapy for a wide range of concerns, you will find especially deep expertise in anxiety, depression, trauma, and addiction. Anxiety and depression often show up as much more than worry or sadness. They can look like overthinking, panic, irritability, numbness, exhaustion, avoidance, self-criticism, hopelessness, or the feeling that you are no longer fully connected to yourself. Hossein helps you slow those cycles down and understand what is driving them. Using CBT and MBCT, he can help you notice the thought patterns and habits that keep you trapped. Using DBT-informed strategies and strength-based work, he can help you build emotional regulation, distress tolerance, and steadier day-to-day functioning. And because he also brings existential and narrative perspectives, therapy can move beyond symptom management into bigger questions of meaning, identity, and how you want to live.Trauma and addiction require the same balance of safety and structure. You need therapy that respects your pace, but you also need a therapist who knows how to guide the work instead of leaving you alone with it. Hossein’s background includes trauma-related care, PTSD support, and experience working with addiction issues in complex real-world contexts. He may use trauma-focused CBT, cognitive processing therapy, person-centred support, and motivational interviewing to help you understand triggers, reduce shame, rebuild trust in yourself, and make practical changes that hold outside the therapy room. If substance use or other compulsive patterns have become a way of coping with overwhelming emotions, therapy with Hossein is not about judgment. It is about understanding what those patterns have been doing for you, what they have been costing you, and what healthier alternatives can begin to take their place.
What makes this especially valuable is that these concerns rarely exist in isolation. Anxiety can sit underneath addiction. Trauma can intensify depression. Relationship stress can keep everything active. Hossein works with that whole picture, so your care is not fragmented. You are supported as a full person, not as a checklist of separate problems.
