Bonita Brigman, Ph.D., LPC, LMFT
During my Masters training I made the decision to pursue a career as a therapist because I wanted to work with people to improve their everyday lives. It is far too easy for any of us to get stuck in a difficult place in life. We want our relationships to be happier. We want to do well at school or work. We need support when the tasks of life such as choosing the right partner, raising children or caring for an aging parent becomes overwhelming. We grieve when we are faced with loss and change. We may become depressed or anxious trying to figure out which choice is best for us in life. I enjoy working with clients to meet these challenges.

Joseph McVoy, Ph.D., LPC
I entered this field, in my thirties, as a client and not as a therapist, because I was disappointed with the help that I had received. Although my counselor was very supportive, he offered no direct guidance as to how to carry out the change that I needed. This frustration led me to explore the possibility of going into the counseling field. It seemed overwhelming to even consider at that time. Thankfully, I left my old career and entered graduate school. As a result of my own experience, I now see myself as having the responsibility to both motivate you and provide you with the tools necessary to accomplish your goals. At the same time, I am also the source of encouragement and support as you face the uncertainty of change.

Dr. McVoy is a co-founder of The Cascade Group.  A native of Pensacola, Florida, he obtained his Bachelor's Degree from Kenyon College.  He returned to college in his thirties to obtain his M.S. in Family Therapy and Child Development from East Carolina University.  Subsequently, Dr. McVoy came to Blacksburg in 1985 to obtain his Ph.D. in Marriage and Family Therapy.  His interest in the causes and effects of being overweight led him to research adolescent obesity as his dissertation topic.

The New River Valley appealed to Dr. McVoy so much that he remained in the area once his doctoral education had concluded.  He initially worked as St. Albans Psychiatric Hospital where he developed a family therapy program.  At St. Albans, Dr. Mcvoy became interested in eating disorders and initiated an eating disorders treatment program.  This interest in Anorexia Nervosa and Bulimia Nervosa led him to present to other professionals throughout the United States on eating disorder and obesity issues.

Dr. McVoy left his hospital affiliation in 1996 to concentrate on working in private practice.  This led to the establishment of The Cascade Group in 2002.

Over the past 25 years, Dr. McVoy has developed specialized knowledge in a number of areas:
-Depression and Mood Disorder
-Obsessive Compulsive Disorder
-Eating related Disorders
-Relationship Issues

Rebecca M. Hope, LCSW

I grew up in Buffalo, NY but have never enjoyed the cold and snow! That is the reason I ended up in Southwest Virginia. I completed my Bachelor's Degree in Psychology at the State University of New York at Geneseo and after I graduated, I moved to Massachusetts for several years to get some great experience working in a behavioral treatment center for children and adolescents. Massachusetts was still too cold so when I decided to apply to graduate school, I applied to universities in the south only! I chose to attend the Master of Social Work program at Radford University and graduated in 2003. 

I began working at New River Valley Community Services as an in-home clinician with children, adolescents, and families. For the past six years, I have served as a school-based clinician in a Montgomery County elementary school, working intensely with children with various mental health and behavioral issues. I have a special interest in grief counseling, trauma, and attachment disorders and really enjoy using play therapy to help children express things that they might not be able to put into words.

My husband and I have two young boys, a cat, and a dog, all of whom keep us very busy! I enjoy traveling, shopping, spending time with friends and family, and reading.


Lisa M. Johnson, LCSW

I gravitated towards this field at a very young age starting as an intern in high school at a local services building in my hometown of upstate New York. I immediately became inspired to help support those who were underserved due to trauma exposure, or lack of resources, guidance, and support. I am a firm believer that everyone deserves access to counseling services and the chance to explore and take control of the problems of their lives, listen to their emotions, and be strong participants in making sure their own needs are met. I will journey alongside you to encourage you to utilize and recognize the strengths you have within yourself to make a change.

    Lisa completed her bachelor’s degree in Social Work from Plattsburgh State University of New York and immediately following pursued a Master’s Degree in Social Work at the State University of New York at Binghamton. The core of her experiences involve work with children and families. She has worked in the school system, participated in adventure based outdoor counseling programs with adults and children, and spent 7 years working in a Community Services Board setting in Williamsburg VA. There she provided Intensive In-Home counseling to children at risk and later went on to provide mental health and substance abuse assessments and services to adults before relocating to the Blacksburg area. She now enjoys working with youth as well as adults. Her special interest is in empowering men and women whom have suffered from a chaotic upbringing and are working to break those cycles in their own families and relationships.

Charlotte A. Whitworth, LCSW

Looking back on my life, it is hard to imagine how and why I arrived at this place in my life.  My journey is an example of what one can achieve with an Associate's degree in mental health from Virginia Western Community College.  In 2006, I received my Bachelors of Social Work from Radford University and was accepted into an Advanced Standing track.  In May of 2007, I received my Masters of Social Work from Radford University.  My dream was to become a Licensed Clinical Social Worker, which is typically achievable in 2-3 years.  Little did I know that this goal would take me 13 years to complete.  

During my journey, I often came close to giving up, however I persevered.  Eventually, I achieved what I set out to accomplish and became a LCSW.  As a result of my endeavors, I now work to support others who wish to overcome obstacles in their lives that are holding them back from their own goals.  It is a passion of mine to help clients understand that these obstacles do not need to prevent them from seeing their goals. It is a passion of mine to help clients understand that these obstacles do not need to prevent them from seeing their goals come to fruition.  Whether it be depression, anxiety, grief, trauma or something that is unable to be categorized, I am here to walk with you through this journey.  

Areas of specialties for Charlotte include:
-Individual and family therapy
-Adolescents/College students 

My most beloved roles in my life are being a wife, mother and grandmother.  In my free time, I enjoy spending time with my grandchildren and attending their athletic events.
