Board of Directors



RP (Qualifying)
Certified Solution Focused Brief Therapist

Board Chair
Chair, Advocacy Committee
Chair, PRPA Sub-committee

Chair, EDI Committee
Chair, OSRP-CRPO Committee
Chair, Wellness Committee

I joined the board because I noticed that it is made up of members that are passionate about the call of duty. Also, I discovered that, from the inception of the organization, there have been positive changes. That said, there is still much to do, which requires the help of everyone, especially psychotherapists. I know that I am motivated and possess diverse skills and global knowledge that can be of great use to this wonderful organization. I greatly admire that the organization is made up of leaders that have the best interest of all psychotherapists in Canada at heart. Additionally, I believe that I can best serve the organization as an active member of the board of directors.

I bring with me over 20 years of professional experience within diverse fields, and I have held senior active leadership positions. I have had the privilege to sit on local and global boards. With that said, I am zealous about the advancement of mental health locally and internationally. I am committed to continuing to work towards eradicating the stigma associated with obtaining professional mental health services. Also, I comprehend the urgency for more to be done globally, especially in Canada, to safeguard the field of psychotherapy. Such urgency also brings greater attention to the fact that psychotherapy, like its counterpart, psychology, has its own unique platform and is not second best to any approach.

Board Past-Chair

Kimberly Cato is the Chief Executive Officer and Founder of True Roots Counselling Services where she provides trauma responsive and asset-based services through an anti-racism, anti-oppression, social justice, and somatic abolitionism lens. As an empathic and intuitive Black woman who navigates the world from a wheelchair, Ms. Cato, with intersectional insight, offers therapy, community building, and corporate consultation for those within her sphere of influence.

Ms. Cato is intentionally engaged in dismantling racism by decolonizing therapy through Afrocentric modalities and culturally adapted therapeutic practices that build multi-racial communities that thrive. She is committed to eradicating racism by facilitating healing circles designed to identify and address racial trauma, thereby empowering people to fully manifest their Ancestral Excellence. 

Kimberly Cato is excited about her position as OSRP’s Board of Directors Chair and the process of embedding EDI principles in every aspect of the Society. In June of 2023, the EDI Committee launched the Race-Based Data Collection Initiative to establish a baseline understanding of who makes up the membership and who is missing from decision making tables within the Association. The resulting data aids in creating a space in which race and other forms of marginalization are not barriers to entry into the field of psychotherapy, resulting in an OSRP that can accurately represent the diversity of the community seeking therapy in Ontario.

Chair: Connect Committee

I am an integrative psychotherapist and integral professional coach™, in private practice since 2011. I draw from a variety of modalities such as psychodynamic, trauma-informed, developmental theories, complex systems, and cultural identity theories to name a few. Most of all, I am inherently curious about life, exploring this thing called being human and the universal qualities we share. I bring an intentional focus on what connects us, rather than on what creates division. My own immigration experience has brought special attention to what it means to cultivate a cohesive cultural identity and sense of self when the host culture and original culture are at odds. In my practice I support individuals and groups to locate their sense of cohesion and inner compass, honouring the multiplicity that makes them who they are with the unique gifts they bring to the world.

In my personal time I nourish myself by cycling, spending time in nature, drawing, dancing, traveling, reading, and spending quality time with loved ones. I am creative and playful by nature and bring those qualities to everything I engage in, including my work.

My wish is that by joining the OSRP board I can be of service in supporting our members feel part of a larger whole, a place where their beautiful complexity is welcomed and celebrated.

Co-Chair, Advocacy Committee 

I am a Palestinian Canadian whose life was greatly impacted by the experience of childhood immigration and political developments in the Middle East. In my spare time, I fight injustice and inequality as a human rights activist and community organizer. I have also worked with immigrants and refugees, providing settlement services and group counselling sessions. My passion for psychotherapy stems from my conviction that a better world is possible.

As hard as change was for me in my own life transitions, it would be change that would drive me forward; the desire to understand myself and improve, to do the work that would be necessary to become the person I am today.

I hope to bring my passion for change to the OSRP as we continue to grow and inspire.

Executive Committee

The Executive Committee is the nucleus of the OSRP Board of Directors. Members of the Executive Committee include the Chair, Vice-Chair, Past-Chair, Treasurer and Secretary of the OSRP Board, and any Board members and any other members in good standing that the Executive may, from time to time, appoint.

The Executive Committee provides a concentrated administrative function for the OSRP Board. Each month, it reviews the past and planned work of the Board. It also receives and discusses any pressing issues that have suddenly emerged from inside or outside the organization. With this information, the Executive Committee sets priorities and plans the agenda for the upcoming Board meeting. It reports to the Board its recommendations concerning any significant action or policy that is not part of another committee’s work to bring forward or to carry out.With the Treasurer, the Executive Committee monitors OSRP financial matters. With the Secretary, the Executive Committee monitors minute keeping and communication among Board members. It is the committee within which the past, current and next OSRP presidents confer to provide joint leadership to the Board and the organization. The Executive Committee as a whole is responsible to maintain, on behalf of the Board, a useful working relationship with the administrative management service provider hired by OSRP, currently Funnel Communications. The Executive Committee is responsible for organizing and executing the Annual General Meeting of the OSRP, which includes a meeting of the Membership Council and a Business Meeting. The Executive Committee meets monthly, usually one week before the monthly Board Meeting. Other meetings may be scheduled as necessary.

Advocacy Committee

Co-Chairs: Hammam Farah, Natasha Tuletta-Bowman, Maria Wallis

This committee advocates on issues that benefit and impact Registered Psychotherapists as a whole. The Advocacy Committee aims to stay aware of policies and issues affecting RPs coming from the College, provincial and federal levels of government, the media, membership requests, and related sectors especially mental health, professional training and insurance. The Advocacy Committee determines (“triages”) which issues to pursue based on urgency, relevance, impact on RPs and available committee resources and engages with the respective stakeholders to influence policies for the benefit of the practice of psychotherapy. Advocacy is a huge portfolio and requires many volunteers to cover it fully. That is why the OSRP joined forces with the 12 other psychotherapy associations in Ontario since the early 2000’s in order to include our voice with others when we couldn’t possibly cover every issue ourselves. OSRP is both a leader and a joiner in advocating for RPs.

Equity, Diversity and Inclusion Committee

Chair: Natasha Tuletta-Bowman
Co-Chair: Alethia Cadore

The Equity, Diversity and Inclusion (EDI) Committee understands that multiple approaches and points of view make up the core values of the practice of psychotherapy. It also understands that exclusion and racism are systemic in our culture and have affected our practices in deeply embedded, often unconscious ways. The committee, therefore, aims to ensure that residents of Ontario, including our most marginalized, vulnerable populations, are able to confidently and safely access the highest standards of therapeutic care available.

And we intend to make sure that our practitioners receive as much insight and support as they need in order to bring their empowered, full and authentic selves to the conversation. This pioneering initiative of the OSRP holds anti-racism, anti-oppression and social responsibility as its defining ideals.
