Who We Are

Core Team

Geri Lynn Peak  is Chief Insight Facilitator at Two Gems Consulting Services.  She and her associates work to strengthen community-based, regional, national and international programs through evaluation, training and technical support.  She seeks to shine light into the dark corners of program practice to promote true understanding by: 1)  asking critical questions with curiosity and compassion; 2) "listening" to what is learned through diverse approaches to gathering and mining data with openness and detachment; and 3) presenting that wisdom back to clients in accessible forms, trusting in them and helping them invoke their own wisdom and excellence to continually improve their efforts. 

Two Gems practices evaluation based on a process Geri developed called Strategic Insight Facilitation, which involves gathering wisdom using customized participatory data collection activities to learn what stakeholders know about program operations, practices, outcomes, challenges and benefits and using those insights to drive evaluation questions and design. 

Geri  also owns a much neglected wearable arts business and performs dance, drumming  and song on occasion as the community requires it.

Lisa Robinson provides data and analysis services as an Insight Facilitator with Two Gems Consulting Services and manages her own independent firm, LL Robinson Consulting Services, providing data management support for local and national programs and institutions. Lisa has expertise in quality assurance, database management and data quality control.  She works directly with clients to help them maintain excellent data and deliver that information to support telling their stories.   

Lisa received her Bachelor's degree in psychology and medical humanities from the University of Delaware.
