Liza's full resume

Joel De Mesa is a senior consultant 

Joel is an endearing and energetic trainer/fac ilitator who is able to build a common goal, communicate it effectively to participants and navigate a learner-centered process to achieve the objectives.


An innovative, flexible and fun facilitator, he always creates learning opportunities for full and meaningful participation, and makes sure that participants leave the workshop feeling better about themselves – personally and professionally. 

He is very comfortable working with different kinds of people with a wide range of backgrounds and guiding them through a learner-centered process that is both results and relationship oriented.Through this, he challenges participants to confront their personal attitudes and identify what this means for their work. Facilitating can include curriculum development.


He has both the skills and experience to add value in the areas of sexuality and gender, sexual and reproductive health, HIV & AIDS, LGBTIQ work, stigma and discrimination.

Without doubt, training is Joel’s core expertise. He has been organizing training, including training of trainers, since 1998. Although his focus is mostly on HIV & Aids and sexuality, he has applied his training skills to other areas such as counseling, peer education, gender, staff development, strategic planning or focus group facilitation. 

Joel is the referent on training issues within the Woodseer group of consultants.


Joel has been working on program development for HIV & AIDS, MSM and Transgender Organizations for 11 years. This involved technical support to strengthen MSM and Transgender organizations and build their capacities to implement program activities in the area of training, peer education and advocacy.
