This chapter explores the application of the 2015 Multicultural and Social Justice Counseling Competencies (MSJCC) in conjunction with an eclectic family systems when counseling a Latin@ family. The Martinez family was referred to family counseling due to concerns of one of the children's school counselors, regarding a possible eating disorder diagnosis. The case study includes a rich description of the first session with the Mexican-American Martinez family, and examines family dynamics around the identified client, Javier. The Martinez family includes the following members: (1) Mañuel, Javier's 41 year-old father who owns his own construction business; (2) Camila, Javier's 38 year-old stay-at-home mother; (3) Alejandro, Javier's 17-year-old brother; and (4) Isabella, Javier's 12 year-old sister. A discussion of the author's cultural background, counseling approach, and use of the MSJCC lens when working with the Martinez family is also included. Initial goals and prognosis for treatment are considered.
