Who We Are

The Association for Contextual Behavioral Science (ACBS) is an organization dedicated to alleviating human suffering and advancing human well-being. As a regional chapter of ACBS, our mission is to help carry out the goals of ACBS at a local level.

Our Board

Staci Martin-Peron


Staci Martin is a psychologist working at the National Institutes of Health in Bethesda, MD.  She conducts research on ACT interventions for chronic pain, and provides clinical support to medical patients from children through adults.  She has been serving on the board of the Mid-Atlantic Chapter of ACBS since 2011.

Amelia Goodyear


Amelia Goodyear is a social worker at the Uniformed Services University of Health Sciences (USUHS).  She provides therapy for couples, families and military service members, with a special focus on domestic-violence related issues. Amelia‚Äôs vision for MAC-ACBS is to continue to spread training and knowledge of ACT to other clinicians, particularly new clinicians, throughout the Mid-Atlantic area. 

Ron Kimball


Ron Kimball is a clinical psychologist in private practice in DC.  He's a founding member of MAC-ACBS.  He has worked in many places and many modalities but is very happy in his 

work with Contextual Behavioral Therapy.  He would like to find a way to squeeze CBT and Attachment Theory into closer alliance.  In the meantime, helping make
MAC-ACBS the "goingest" chapter in the Association will do nicely. 


Chris Wemple


Chris Wemple is a psychologist in DC.  He has been involved in studying, using and teaching ACT for ten years. A founding member of the Mid-Atlantic Chapter, he is currently the Secretary of MAC-ACBS.

Kristina Murani

Student Representative

Kristina Murani is a doctoral student in the Clinical Psychology Ph.D. Program at American University (AU). Kristina served as Student Representative of MAC-ACBS in 2015. Her previous exposure to ACT in a clinical setting utilized in the treatment of substance use disorders sparked Kristina's interest in learning and becoming trained in the ACT model. 


Miranda Morris


Miranda Morris is a psychologist in private practice in Bethesda, MD.  She uses ACT to treat a broad range of difficulties.  Miranda co-founded the Mid-Atlantic Chapter of ACBS (MAC-ACBS).  Over the past decade, Miranda has been endlessly impressed by the warmth, generosity, and intelligence of the ACBS community.   She is equally bowled over by the MAC-ACBS Board and chapter members.




Laurentia Ruby

Member at Large

Laurentia is a clinical psychologist with a private practice in Fairfax, VA. She has been involved in learning and applying ACT principles in her private practice for about 5 years, and has served on the board of MAC-ACBS as a member-at-large since 2012.  

David Jeffries

Student Representative

David Jeffries is a doctoral student in the Clinical Psychology Ph.D. program at the George Washington University. David currently receives supervision in ACT for individual psychotherapy and co-facilitates an ACT group at the DC VA Medical Center. David believes clinical work will increasingly rely on how well psychotherapists can model and interpret a means to increasing psychological flexibility. He looks forward to continuing ACT-based work with the ACBS community while on the 2016 MAC board.
