Meet The Team

​Board of Directors

Eric M. Welsh, Founder and Executive Director
Born and raised in Northern Arizona, Eric has always been fascinated with the beauty and intrigue offered through National Forests and Public Lands. His interest in Geology grew after taking an introductory class at Yavapai College while working on AA in Business Administration  this inspired him to continue his education and enroll in the Geology Program at Northern Arizona University where he earned a BS in Geology. Upon graduating from NAU, he formed a consulting agency and began working as a geologic consultant with individuals and small companies looking to claim mineral rights or expand operations on existing claims by completing basic survey, mapping, and safety assessments on a contractual basis. After working with small miners in the Nevada desert, he was awarded a GeoCorps Internship with the BLM which lead to his being contracted as a liaison with the Bureau of Land Management in the Abandoned Mine Lands (AML) Program in New Mexico assisting in their inventory and remediation project work as a geologic consultant. It is through this experience that Eric decided to change his consulting agency into a non-profit organization benefiting geoscience students struggling to find jobs due to lack of experience or contacts within the industry. It is Eric's dream to create an environment through GEM's programming where students can apply the knowledge they have acquired in school to the practical industry applications used by many leading geologic and mining companies before they graduate, giving those students a higher chance at landing a job in their area of study, post graduation.

Alejandro "Chino" Martinez, Diversity Officer
As a native Arizonian, Chino has always felt a certain responsibility and commitment towards the community that raised him. This sense of responsibility inspired him to begin taking psychology classes at Yavapai College. While attending his first semester, Chino quickly developed a deep passion for charitable work. He fell in love with the rewarding feeling gained through nonprofit work while attending community college. This resolve stuck with him through the rest of his collegiate years, leading him to complete a Bachelors in Social Work at Northern Arizona University. After 5 years working with several different behavioral health nonprofit companies, Chino decided to continue his dream and further his education. Now working towards a MS in Professional Counseling, Chino hopes to continue his support for our local community and is happy spending his days keeping Arizona and Prescott an amazing place to live, one program at a time.

Robert Briggs, Operations and Program Technician - Member at Large
Robert, a 21-year resident of the Prescott area, moved to Yavapai County from Sacramento when he was 25 years old. After working as a reputable auto mechanic for 20 plus years, he elected to change his career path and made the decision to return to college life as an older student at the age of 42. With persistence and dedication, he graduated in the spring of 2015 from Northern Arizona University with a BS in Geology. During his work in the auto industry, he attained ASE Master Tech certifications and developed the ability to fix just about anything. This has led to a unique opportunity for Robert to join GEM as our fleet supervisor and as a contract geologist working with our Abandoned Mine Lands Inventory team. He thoroughly enjoys being outside with his eyes constantly on the terrain. His experiences working in the automotive field and his renewed zest for geology offer GEM a unique ability to visit remote field locations without fear of being stranded.

Madison was raised in Georgia with a loving, close family. She graduated summa cum laude from Georgia College & State University in three years with a Bachelor’s in Psychology and a Minor in Mathematics. She worked as a mathematics tutor at the college and as a legal assistant at a law firm while attending GCSU. She knew that she wanted to serve her country after college and joined AmeriCorps VISTA to help fight poverty through indirect service. After being raised by a science teacher mom and a data scientist dad, she realized that one of the best ways to help combat poverty is by creating STEM educational opportunities for children while collecting data that confirms those opportunities are working as intended. She is very excited to be part of GEM and has already fallen in love with the beautiful city of Prescott. During her off time, she can often be found working on other charitable projects, kayaking on Watson Lake, or rock climbing in the Dells.
