Experience, Relationships, Results-driven

OpCom Global is led by two intrepid technology industry professionals with a combined 7 decades of experience, Mark Weir, CEO and founder of CMW Consultants Limited and Melissa Esquibel, President and founder of Melissa P Esquibel LLC. When they became acquainted in 2019, they realized that their willingness to seek solutions for their clients by considering the realm of possibilities, not just what was available “in the box,” made them a potential dream team in changing times. The times changed and these two put their heads together looking for opportunities to effect positive change in a world that was suffering from remarkably new challenges and old tool sets.
