Throughout my career, I’ve been sought to develop business in new markets, turn around sales in underperforming regions, and accelerate growth in established markets. At the same time, I’ve enjoyed building and leading large, customer-centric teams that are instilled with the mindset that we’re in the business of providing innovative solutions to meet every client’s unique needs.

I’ve also held operational roles which have complemented my sales and leadership background. It’s been rewarding to identify cost-saving opportunities and to improve top- and bottom-line results by streamlining back-office processes and procedures. 

My global experience includes regions spanning the U.S. and Latin America (LATAM) and I’m proficient in Spanish and Portuguese with a deep respect for diverse cultures and people. 

Highlights:

STRATEGIC PLANNING & EXECUTION – Developed and implemented sales strategies that enabled Adtran to deliver telecommunication solutions for corporate clients in LATAM and catapult revenues in a historically low volume market (less than $2M annually) to more than $30M annually. Built strong and cohesive relationships with distribution and alliance partners.

LEADERSHIP & TEAM DEVELOPMENT– Motivated, mentored and led numerous teams of managerial, technical and sales professionals including project and supply chain managers, account managers, and solution engineers who contributed measurably to the growth and success of companies such as Nokia Networks and Adtran. Groomed a team to hit 120% over target while increasing ROI in one of the most competitive markets worldwide. 

SALES & BUSINESS DEVELOPMENT – Built a robust network of industry contacts that have been instrumental in uncovering new opportunities and have maintained strategic relations that have been vital in adding additional revenue streams.
