Vanguard Therapy was founded by Nancy Shawki LCSW-C, and was created on the tenets of an eclectic style of therapy utilizing different treatment modalities to assist clients in reaching their optimal level of functioning. Nancy believes that people have the capacity to change provided they are afforded the right atmosphere. At Vanguard Therapy treatment methods are always customized to help meet each client’s or family’s needs. Nancy uses a variety of  therapeutic modalities including eclectic, cognitive-behavioral, DBT, life coaching, solution-focused, family therapy,couples therapy, and individual therapy.

Nancy has been in the field of social work for over 10 years and has broad range of experience varying from the mental health arena, adolescence and the school system, families & couples and individual therapy, domestic violence victims & perpetrators, case management, crisis intervention, and child protective services. These experiences in the field of social work have provided me with a well-rounded exposure to a variety of social service settings that I feel have prepared me to work well and adapt to any situation in the mental health and field of social work. My goal as a therapist is to provide a healthy, nurturing, and professional atmosphere that allows my clients to feel supported in their journey to wellness. As a therapist, I always feel honored when clients feel comfortable to express their deepest thoughts and private life story and journeys because each one is very sacred and precious.

Nancy feels being a counselor and therapist is an honor and privilege to help others heal in their journeys in life. It is a very intimate moment and dynamic in therapy when a client fully trusts me and allows me in their lives by telling me their journey and personal story. As a therapist, I’m excited to depart my clients with knowledgeable information that they can utilize as coping skills or tools to enhance their relationships and lives.

Nancy and her husband are the proud parents of two young girls and when she is away from the office she enjoys spending time with her family  creating memories. During her spare time, she enjoys reading, scrap booking, music, engaging in public speaking events about wellness and mental health, and volunteering in the community. Nancy serves as a volunteer couples group leader helping couples have enriched and happy marriages.

Tina's Email Quote: To laugh often and much, to win the respect of intelligent people and the affection of children, to earn the genuine appreciation of honest critics and endure the betrayal of false friends, to appreciate beauty, to find the best in others, to leave the world a bit better, whether by a healthy child, a garden know even one life has breathed easier because you have lived. This is to have succeeded! - Emerson -
