Dwight Tolliver, Ph.D., Owner, Psychologist, Co-Author of Gentle Mending

Dwight earned his Ph.D. from the University of Tennessee in August of 2008. During the educational and training process, he worked in a variety of settings and with a variety of populations. Specifically, he has worked in community mental health centers, university counseling centers, and with a crisis organization for children and adolescents. Dwight completed his pre-doctoral internship at The Ohio State University’s Counseling and Consultation Service.  Dwight has been a licensed psychologist in the state of Ohio since 2009.

Mending, Growth, and Empowerment:

Dwight’s orientation toward clients has a fervently humanistic slant to it.  In essence, this symbolizes a desire to build, create, and foster relationships with clients that matter for the clients.  To achieve this type of relationship, Dwight attempts to understand and connect to the whole human being, suggesting that acceptance is as important as change.  Dwight views the therapeutic journey as a process of mending, growth, and empowerment, which can be accomplished by attending to the processes of daily living such as making routine decisions AND processes of existential living such as how human beings seek purpose and meaning in Life.  

Dwight has a deep respect for clients, hoping they feel his care and concern as well as his belief in their ability to change. In this light, he views his role as one where he helps clients feel empowered to interact with others, the world, or themselves differently and to develop the confidence, resilience, and belief to live a sustainable Life. Dwight has been trained as a generalist and embraces his ability to work effectively with diversity and most presenting concerns (e.g., trauma, loss, ADHD, depression, anxiety, substance abuse). He is also proud to be the owner of Affirmations Psychological Services... where diversity, social advocacy, and the belief in the human spirit are appreciated, valued, and nurtured. Dwight sees clients at our Broad St. location.

Rachel Secttor, M.A., LPCC, NCC

It all started at Earlham College. Rachel Secttor was finishing her senior year and needed help. She found it at a psychologist’s office and, after a positive experience in counseling, she graduated with her Bachelor of Arts in English and Music. Rachel tried a variety of jobs including working in the music industry, nannying a 2-year-old, and real estate management.

While living in Nashville, TN she decided it was time to go back to school and become a counselor herself. Rachel got her Master of Arts in Clinical Mental Health Counseling at Trevecca Nazarene University while working at Starbucks. She moved to Cincinnati in 2015 to complete her internship at Xavier University. The day after she finished, she started working at Eating Recovery Center of Ohio in Cincinnati.

In graduate school, Heidi worked with college students in the Student Counseling Center at Illinois State University. She also worked in a local mental health center during her graduate training with clients who had mental health and substance use issues. Her first job placement was working with adults who had suffered brain injuries at a rehabilitation center in North West Chicago.

Upon moving to Columbus with her husband, Heidi worked for a private practice treating children and adults who were referred by their physician. She also worked for a local mental health center with the chronically mentally ill population. She then moved on to working for Adena Medical Center’s outpatient counseling center with children and adults doing both groups and individual counseling.

Heidi has worked for the last 18 years with individuals with mental health, trauma, and addiction issues at CompDrug, Inc. where the primary clientele was individuals with opioid addiction issues on medicated assisted treatment. She had experience there with both individual and group counseling. She has been trained in EMDR (Eye movement Desensitization Reprocessing) since 2001 which is a therapeutic technique to assist individuals with unresolved trauma, grief and loss. Also, during her time there, she trained with Brené Brown and became a Certified Daring Way Facilitator. Brené Brown’s work focuses on shame resilience, vulnerability, self-compassion, authenticity and living a whole-hearted life. This certification allows her to facilitate both The Daring Way and Rising Strong curriculums in groups or individually to help people move through difficult shame issues.

Heidi is trained as a generalist, and is comfortable working with most presenting concerns (trauma, addiction, grief/loss, depression, anxiety, life transitions, parenting, caregiver stress, co-dependency, chronic illness/health issues, and

communication/relationship issues) and is passionate about working with people who have been marginalized by society. Heidi’s experience has had a focus and training in attachment theory looking at the influence of family of origin issues on how we develop as people and interact in relationships. She looks at how our experiences and traumas forms us, looking at the patterns we have fallen into, examining our values and helping you be your authentic self to allow for full connection in relationships.

Todd Carter, LPCC-S, LICDC

Todd A. Carter is a Supervising Licensed Professional Clinical Counselor (LPCC-S) and a Licensed Independent Chemical Dependency Counselor (LICDC), who specializes in treating mental health and chemical dependency issues. Todd grew up in Groveport, Ohio. In 1990, he received his Bachlor's degree in psychology from Capital University in Bexley, Ohio. In 1992, Todd received a Master's degree in counseling psychology from Illinois State University and in 1996, he obtained second Master's degree in counselor education with a focus on Social Agency Counseling from the University of Dayton. In 2002, Todd completed the level II training for EMDR, a specific therapeutic technique used to assist clients in resolving traumatic experiences. 

During his graduate studies, Todd worked with college students in the Illinois State University Counseling Center. He also worked at a local mental health center with clients dealing with mental health and substance use issues. Todd's Master's Thesis looked at how people adjust to multiple grief and loss experiences. Following graduation, Todd lived in Chicago working for two years at Community Counseling Centers of Chicago, the largest mental health center in the city where he worked with chronically mentally ill clients with a history of multiple psychiatric hospitalizations.

In 1994, Todd and his wife, Heidi returned to the Columbus area. Todd worked in the Emergency Services Department at Southeast, Inc., a mental health center serving clients with chronic mental health and substance use issues. Todd worked next at Netcare where he preformed mental health and substance abuse assessments on clients seeking linkage to community mental health services.

While Todd would consider himself a generalist, in that he works with a variety of mental health and addiction issues, Todd also has clinical areas of specialization in grief, trauma, and the treatment of PTSD. His approach to treatment is a combination of looking at the influence family of origin experiences have on the development of mental health and addiction issues, the impact of traumatic events on brain chemistry with a strong belief in utilizing psychiatric medications for symptom management/treatment of these chemical imbalances in the brain with a large focus on the utilization of Medicated Assisted Treatment in the long term treatment of addictive disorders.

Todd places importance on helping clients gain an understanding of the impact traumatic events have on clients' present day functioning without continuing to allow these experiences to define our personhood/life legacy. Other foci of his work with clients includes examining different kinds of dysfunctional attachments with others with the hopes of adjusting interactions toward healthier ways of relating to others, and skill development of sensory modulation/grounding techniques to decrease emotional dysregulation/high states of physical arousal (living in a tense body/fight, flight, or freeze (sympathetic nervous system) with the goal of spending more time in a relaxed body (parasympathetic nervous system).

For the last 21 years, Todd worked at Compdrug as a counselor providing individual and group therapy services to clients on Medicated Assisted Treatment for Opioid Dependence. Todd also served as a clinical supervisor for professionals seeking their independent counselor license.
