About Boundary Spanning Panel



Aaron Brownlee

Having earned an MA in Clinical Psychology and working in residential treatment with youth, Aaron Fell into working as an IPS Employment Specialist in a Community Mental Health program in Chicago. This led to work with Oregon VR. As someone who has frequently checked the “other” box in life and experiencing my world change though my own coming out process he has observed how systemic functioning disadvantages his fellow “others” and daily works to reduce that discrepancy.



Teddy Walston

Born with Cerebral Palsy, my greatest fear was that I would be just another talented New Yorker with a disability and nothing to show for it. As an Oregon Vocational Rehabilitation Counselor for the past seven years, I have been able to face and conquer this fear alongside wonderful clients and colleagues. My road has been paved with stones of struggle and triumph. I continue to find strength in my family, faith and belief that if we as humankind embrace our full capacity to love, we can overcome all obstacles.
