Executive Director

Pronouns:  She, Her, Hers

Christa has been with Open Aid Alliance since 2008 when she began as an HIV Prevention Coordinator. She became the Executive Director in 2010 and has been dedicated to the evolution and growth of the organization ever since. She is passionate about providing leadership to address challenging and complex human conditions and Open Aid Alliance is a part of her heart. When the concept of harm reduction was introduced to her she could feel it ignite every cell of her body and knew that there could be no other right way for her.

Christa is a work in progress and she is humbly reminded of that daily as she navigates life both professionally as a leader and personally as a mother. Messy and Wildly Fulfilling are adjectives she might use to describe her life.

Amanda Reese: People who Use Drugs Deserve Compassionate Care

Uncovery Clinical Director, Licensed Clinical Professional Counselor

Sarah started working at Open Aid Alliance while completing her internship in Clinical Mental Health Counseling. Working with so many people that had been rejected from care, it was evident that Open Aid Alliance needed increased capacity to nurture and care for those experiencing shame, rejection, addiction, trauma, isolation, and hopelessness. Uncovery Treatment Center was born.

Sarah is passionate about creating atmospheres of inclusion and belonging, so everyone can receive the care they need and deserve, no matter what.
Trained in Addictions Counseling and Harm Reduction Psychotherapy, Sarah can help clients work towards reducing harm in their lives and towards creating the changes that stir inside their souls. Trained in working with Altered States of Consciousness, Sarah is skilled at working towards integrating substance-related and mystical states to regain balance in one’s life.

Trained as a certified Mindfulness Meditation Teacher, Sarah loves teaching the skills of awareness and listening to tap into deep inner wisdom and freedom.
Sarah is a Somatic Experiencing (SE) Practitioner and is skilled at guiding clients towards healing through nervous system regulation. SE is a modality to heal all forms of trauma.

Sarah has long led groups for personal and social transformation as well as taught at retreat settings for both youth and adults.

On her off time, she can be found on a mountain top, howling at the moon.

Clinical Therapist, Uncovery

Pronouns: She, Her, Hers

Tomi has lived in the awe-inspiring state of Montana since 2012 and has worked for the amazing Open Aid Alliance Team since 2019. Having lived experience with both IV drug use and homelessness, Tomi is passionate about harm reduction and the human potential for positive change and healing through connection and dignity. She studied Human and Family Development and has a Masters degree in Clinical Mental Health in support of this purpose.

Harm Reduction Therapy is a commonsense and humane approach to healing. A client does not need to be abstinent or even be seeking abstinence in order to receive counseling services. Instead, this risk reduction counseling honors and supports your right to choose what works best for you in your life. It's an honor to get to walk through the darkness and the light together.

When Tomi is not with all the cool folks at OAA, she's in the backcountry of the mountains, at a concert, or in a hammock or hot spring with the loving humans (and animals) in her life, and a good book.

Harm Reduction Program Specialist
IT Specialist, Intake Coordinator

Pronouns:  He, Him, His

As a dad, punk rocker, and bicycle enthusiast.  I appreciate the services, compassion, and understanding Open Aid Alliance provides people like me.

In IT for over 25 years,  my work has mainly focused on the unique needs of small businesses and nonprofit organizations.  I've helped my clients with basic computer service and desktop support to complete network and infrastructure management.

I have been involved with Open Aid Alliance for about 6 years in different capacities. As an IV drug user, I was a client of the syringe exchange program.  As a volunteer, I assisted with various IT and program related matters.  I am now employed full-time with OAA as their IT Specialist.  At 49 years of age, I have found my passion.  Supporting OAA so they can support their participants brings me joy and satisfaction each day.

Recovering addict says Open Aid Alliance of Missoula saved his life


We made a quick little time-lapse of everyone preparing the meal from our 2019  World AIDS Day Dinner. It was hectic due to a tight timeline, but everything fell into place like we planned and everyone had a good time. The food was excellent and it was a great staff experience. We have a great group here at OAA (if I do say so myself… and I do) and it was fun to do something different together.
