Ruth Galloway, LCSW
Licensed Clinical Social Worker
Throughout my career I’ve had the good fortune to work with both men and women dealing with emotional issues and self-defeating behaviors. My experience includes helping clients work through relationship issues, anxiety, depression, substance abuse and low self-esteem. Additionally, I have a special interest in working with clients who have experienced trauma and grief and find that the use of Rapid Resolution Therapy in these instances has a remarkable positive impact.
As a therapist, I believe that trust and connection is essential in helping clients to heal and grow and that therapy is the interactive process which assists the client’s own ability to heal. I utilize a variety of treatment approaches including cognitive behavioral therapy; rapid resolution therapy/hypnotherapy; guided imagery meditation and interactive psychotherapy, all tuned to the individual.
I am a graduate of the University of Georgia and Georgia State University. I am a licensed clinical social worker with 25 years of experience in both direct clinical practice as well as having served in the capacity of program coordinator and director of treatment programs in Georgia.

His background in sports and performance works seamlessly with people from all walks of life who may be grappling with obstacles hindering their personal or vocational aspirations, whether in school, college, business, sports, or fitness. Clients come to Sam seeking support, guidance, and accountability for daily or recurring psychological challenges such as depression, anxiety, self-esteem, relationships,
hopelessness, or a lack of motivation. Others may be living with learning disabilities such as ADHD, which can naturally create barriers to taking action. Sam strives to
empower his clients to cultivate a healthier perception of themselves by developing effective coping strategies, to boost confidence, drive, and self-belief.
Sam's primary therapeutic approach is Solution-Focused Therapy (SFT). This short-term, goal-oriented method draws on the principles of positive psychology to help clients construct solutions rather than dwell on problems. For more complex and challenging
cases requiring a longer commitment, Sam employs Multimodal Therapy (MT). This comprehensive approach addresses harmful thought patterns and beliefs, equips clients with emotional management tools, promotes the replacement of unhealthy behaviors
with healthier alternatives, explores physical sensations, and enhances interpersonal skills to improve communication and social interactions.

He is on the path to becoming a registered Practitioner Psychologist with the Health Care Professions Council (HCPC). He is pursuing an
