Kim E. Costello, Psy.D., LMHC

Co-owner and co-founder of The Costello Center, Dr. Kim E. Costello has over twenty years of experience as a therapist and counselor. In that time, she has helped hundreds of individuals, couples, and families through major changes in their lives.

"I believe that the very purpose of life is to be happy. From the very core of our being we desire contentment. In my own limited experience, I have found that the more we care for the happiness of others, the greater is our own sense of well-being."

Dr. Costello's experience and training led her to found The Costello Center with her husband Frank Costello in 2006, a comprehensive counseling and academic assistance center serving the greater Tampa Bay area.

Dr. Costello is a psychotherapist, Board Certified Counselor, Licensed Mental Health Counselor (LMHC), Florida Supreme Court Mediator, Certified Christian Marriage and Family Therapist, Parenting Coordinator, and Neutral Mental Health Facilitator trained in the most current models for family mediation and collaborative law. She received her master's degree from Norwich University and a Doctorate in Christian Counseling Psychology (Psy.D.) from Carolina University of Theology. She is a member of the American Board of Professional Counselors, the American Psychotherapy Association, the Association of Family and Conciliation Courts, and the International Association of Collaborative Professionals.

Conflict resolution counseling has always been an important component of Dr. Costello’s practice. After decades of providing therapeutic intervention for individuals and families in times of marital transition, she came to believe that there is a better way for parents and children to navigate through the painful process of divorce. Through extensive training and professional development, Dr. Costello has gained a unique perspective and expertise in the area of conflict resolution therapy. She believes so strongly in the positive impact of this process that she has shifted the entire focus of her practice in order to more fully dedicate herself to her work with families in times of divorce.

Her innovative method for collaborative divorce has grown as families have realized that divorce without despair is possible. To this end, she is trained in the best methods for family mediation and collaborative law and serves as a neutral mental health facilitator, parenting coordinator, child specialist and/or mediator for families in need. Dr. Costello works to provide services tailored to the unique needs of each family she helps, knowing no two divorces are exactly alike, but the end goal of easing the changes by facilitating communication and cooperation remains the same.
