Ruth Kanatser, Syringe Access Director/Senior Health Educator

Ruth has been an integral staff member with our agency since 2003. In December 2011, Ruth was recognized for her tireless efforts to improve the lives of PWID by receiving the inaugural Josephine Roche Award from the city of Denver for providing excellent direct service to a marginalized community. As director of the syringe access program and senior health educator her time and expertise is spent primarily referring program participants into substance use treatment or other vital services and educating our participants, community members and other service providers around the health issues that can effect PWID and how to reduce said harms.

Ruth has a special passion for trying to improve the historically mistrustful and adversarial relationship between health care providers and PWID through education and advocacy. Especially when concerning pregnant women who inject.

She lives with her husband John and two spoiled kitties who are excellent company for her favorite pass times of reading and napping.


Teresa Hogan, Community Outreach Director/Volunteer Director

Teresa became the HRAC’s part-time CSC in March of 2015. Her introduction to harm reduction principles was kick started by Lisa Raville when she and two participants presented in her Anthropology of Drugs class at the University of Colorado Denver. After recognizing a great need within her own community for harm reduction services, she decided to get involved and started volunteering. Since then she has been a volunteer, intern, and independent contractor for the organization. Her responsibilities in her position as the Client Services Coordinator include Drop-in shelter support, SAP backup and support, weekend outreach coordination, intake coordinator, inventory management, and grant writing.


Kat Humphries, Programs Director

In January of 2017, Kat Humphries joined the agency as the new Director of Programs and Data Evaluation.  Kat spent several years in Denver doing harm reduction volunteer work and is a former HRAC volunteer and fundraiser.  After spending nearly 4 years working in regulatory compliance, Kat was ready for a transition into direct service work. She hopes to bring her knowledge of policy, relationships with funders, and experience writing SOPs and other standard documents to the table to help the HRAC as the agency grows. As Programs Director it is Kat’s responsibility to manage interns, write reports and analyze data for grants, conduct HIV and HCV testing for participants, assist the Senior Health educator in administering individual and group-level interventions, and assist other HRAC staff in facilitating our syringe access program.  As Director of Data Evaluations, it is her responsibility to track and analyze all syringe access data, evaluate program outcomes, and write monthly, quarterly, and year-end reports to submit to funders.

Sophie Feffer, Volunteer Director

Sophie was born and raised in Colorado Springs. She graduated from the University of Colorado Boulder in 2017 with a degree in Sociological Criminology and French. Sophie was introduced to the HRAC when Lisa presented in one of her courses. During the next three years, she became involved as a drop-in volunteer, an outreach volunteer and an intern. Upon graduating, she became a research assistant for three national studies focused on the intersections of incarceration and gang membership. She is especially drawn to the HRAC’s highly accessible public health options for people who inject drugs, as well as the drive to create new harm reductionist policy on a community level. As volunteer director, she is responsible for coordinating all volunteer positions which fully staff the syringe access program during drop-in. In addition, she conducts mobile outreach three times a week alongside other service providers and volunteers.

Stevie Pinkerton, Client Services Coordinator

Stevie has been volunteering with the HRAC since March of 2017 and was hired on as part-time staff in August 2018. He is in charge of our fentanyl testing program and collects all of the data resulting from this program. As recently as November 2017 participants and officials in Denver noticed fentanyl and fentanyl analogues in our drug supply. To ensure our participants can continue to make informed decisions about their drug use, we started a fentanyl drug checking program that would alert participants to the presence of fentanyl in their drugs. Stevie trains participants on how to use the testing strips, has conversations about safer use, and processes refill questionnaires. In addition to these services, he manages the support volunteers each morning, and conducts PWID Advisory Board meetings each month.

Tyler Andreasen, Client Services Coordinator

Tyler is a Colorado native and started volunteering with our program in January 2018. We brought him on as part-time staff in July. Since then, he has been managing our north wing which involves facilitating hygiene donations, deliveries, and supporting our participants to utilize our bathrooms – especially the sinks which are often in high demand. He is always willing to help with other duties and glad that he has joined the team.

Mariela Hernandez Client Services Coordinator

Mariela Hernandez graduated from the University of Northern Colorado May 2019 with a Human Services Major and a Spanish minor. Having interned in the Spring 2019, she decided to join our team in June 2019 as a full time staff member. Her great social skills and passion for serving people has allowed her to create a strong connection with people who inject drugs. As a client services coordinator she helps out during drop-in with referrals and provide overdose trainings with access to Naloxone.
