About Nathalie Héloïse Graveline

Nathalie Héloïse Graveline


I help individuals, families, and frontline professionals solve the complex puzzles that hold them back from thriving.

With over 30 years of experience in nursing and more than a decade as a College of Nurses of Ontario – registered Primary Care Nurse Practitioner, my practice is built on a foundation of deep empathy, specialized expertise, and a commitment to collaborative healing.

As a therapist and coach, I specialize in supporting patients navigating complex health issues, with a particular focus on concurrent disorders (co-occurring mental health and substance use challenges). From my base in Ottawa, I offer compassionate, fully remote care to individuals across Ontario, meeting you in the safety and comfort of your own space.


My Journey: Decades of Dedicated Care

My career has been defined by a desire to be part of the solution for people navigating the most challenging moments of their lives.

Crisis and Acute Care:


I began my journey at the Children’s Hospital of Eastern Ontario (CHEO), primarily in the emergency department—my first love. There, I also served on the Sexual Assault Treatment Team as a Nurse Examiner and trained colleagues as a Nonviolent Crisis Intervention instructor to ensure the highest standards of prepared care.


Community Health and Harm Reduction:


Driven to support underserved populations, I joined the founding multidisciplinary team at Oasis (Sandy Hill Community Health Centre), stepping into the frontlines of the community-based fight against HIV.


Systemic Mental Health Support:


I later collaborated with the Canadian Mental Health Association (CMHA) Ottawa to develop specialized systems supporting unhoused individuals facing severe mental illness, which included time with the Psychiatric Rehabilitation Team at Salus Fisher.


Advanced Clinical Leadership

In 2009, I graduated from the University of Ottawa with advanced practice credentials to become a Primary Care Nurse Practitioner, focusing my postgraduate studies heavily on concurrent disorders. This qualification allowed me to take on a new level of clinical responsibility—providing comprehensive primary and episodic care at Oasis, and delivering specialized consultations for clients and frontline teams at Newgate 180.

Beyond direct therapeutic care, I believe that nursing is fundamentally about teaching. Over the years, I have had the privilege of mentoring medical residents and nurses, as well as presenting workshops on mental health and addictions at provincial and national conferences.


Why I Do This Work Today

Having navigated my own personal health challenges, I have a deep, firsthand understanding of how vital—and difficult—it is to maintain a true work-life balance. This lived experience inspired me to establish an independent practice that fully reflects my values and respects the human rhythm of recovery and wellness.

Today, Even Keel Health is a fully virtual practice. Whether you are a healthcare provider facing burnout, an individual managing an intricate health diagnosis, or a family struggling with a loved one’s mental health or addiction, I am here to coach and guide you back to stable waters.
