Olivia Hoffsuemmer
Occupational Therapist


Hello, I'm Olivia! I graduated with my Masters in Occupational Therapy from Queens University, after completing my Bachelors degree in Psychology and Disability Studies. I have worked with individuals of varying ages and abilities in several settings, including homes, schools, and summer camps. I am so excited to bring all that I have learned from these experiences together at TWO centre. 

As an occupational therapist, my role is to help your child improve their functioning in daily tasks by developing fundamental skills such as handwriting, fine and/or gross motor skills, sensory processing, emotional regulation, and self-care skills. I strive to create a safe space in which my clients can have fun, and feel empowered to unlock their potential.  

During my free time, you can find me reading, going to the gym, or eating my way through Vancouver. 

I look forward to meeting you!


Monday: 6 – 6:45 (biweekly)
Wednesday: 1 - 1:45, 2:15 – 3
Thursday: 4:45 – 5:30 (biweekly)

Please email Olivia directly to book in sessions.

Hi there!


My name is Karen and I am one of the OTs working at This World’s Ours. I have been an OT for 14 years and have specialized in pediatrics for more than 13 of those years. I graduated with a Master of Occupational Therapy from the University of Manitoba after completing my Bachelor of Science (Honours). I have had the pleasure of working in clinical and community settings with children and their families, school teams, and support systems in Manitoba, Alberta and now beautiful BC.


I am passionate about providing services using a neurodiversity-affirming and strength-based approach, and I believe that therapy is most effective when it is fun and joyful! I work closely with families to support children’s development related to goals that are meaningful and important to them. This could include self-help skills (dressing, eating, toileting), fine motor skills (managing fasteners, holding a crayon, printing, using scissors), executive functioning skills (time management, planning, organization), emotional regulation (managing and responding to emotional states), sensory integration (receiving and organizing information from our senses, and using it to participate in everyday life), and much more.


Please reach out if you have any questions, for additional information, or would like to discuss scheduling a session.


I look forward to hearing from you! Email me at

Hi, I’m Emma! I graduated with a Master of Occupational Therapy from the University of British Columbia after completing my Bachelor of Kinesiology with a Minor in Psychology. I am fluent in English and Mandarin.

I have over 10 years of experience working with children of all abilities. I worked as a Pediatric Occupational Therapist in clinical and community settings, and as an Education Assistant and Adaptive Recreation Programmer in schools and community centres. In my practice, I strive to create safe and collaborative environments, while using a play-based and evidence-based
approach, where families feel heard and included in the process.

As an Occupational Therapist, I can work with your child to improve their function in daily tasks. This could include self-care skills (eating, dressing, toileting), fine and gross motor skills, emotional regulation, executive functioning, and sensory regulation. I also have formal training in using the Cognitive Orientation to Daily Occupational Performance (CO-OP) approach with individuals with motor challenges.

I am passionate about ongoing professional development and actively engage in training to stay up-to-date with current research and practices. I have conducted academic research on screen time guidelines specifically for children with Autism Spectrum Disorder (ASD) and completed courses related to cognitive flexibility in children with autism, sleep health, sensory processing in children, and the importance of play. In my spare time, I love trying new food, playing board games, kayaking, and walking in nature.

Available Mondays from 1 pm to 8 pm and Wednesdays from 9 am to 12 pm.

Please email me at if you have any questions or want to schedule a session. I look forward to meeting you soon!
