For the six plus years that I’ve been with Indigo Energy my single greatest pride comes from the relationships I’ve built and maintained with customers and vendors. I’ve relentlessly practiced a customer-first mentality in everything I do. It is one of the few things I can control on a day-to-day basis and is the cornerstone for every successful relationship I’ve been a part of.
With over 30-years experience in the industry, I have created a nationwide network of business partners to handle any emergency from hurricanes to blizzards. I work closely with government as well as commercial accounts. I have extensive logistics capabilities and can negotiate the best rate for my customers, from generator fills to bulk storage.
First-class customer service and professionalism are my guiding principles when it comes to supporting my customers. Through constant contact and collaborative partnerships, I’m able to support my customers’ needs and develop creative solutions to their day-to-day problems. I thrive helping my customers navigate through emergency situations, and pride myself in the ability to work in an ever-changing face paced environment.
I have been embedded in the Energy Sector for 10 years and have developed an immense passion for the industry itself but more importantly the relationships I have built along the way. I believe in and value reliable customer service and aim to pass along the core values that support our industry to all customers.
With many years in the energy industry, I have learned that integrity, trust, and hard work are the most key elements in business. I will always go the extra mile for customers. Having great supplier relationships and in-depth industry knowledge across the U.S. positions me to give my clients the strongest support and supply possible, no matter the circumstance. I do my best to always find a way and take care of my customers.
