Alexander Melgar is a visionary entrepreneur, speaker, and business coach extraordinaire. From a modest restaurant owner in El Salvador to the founder of a top-ranking nationwide facility maintenance organization, Alex has sculpted his journey with determination, learning, and an innate calling for entrepreneurship.

Ambassador Services

Alex founded Ambassador Services after having worked as a floor technician and experiencing firsthand what it means to tend to the needs of customers. His enterprising experience in the hospitality sector gave him the knowledge, confidence, and expertise to set the foundation of a company based on solid core values: honesty, commitment, and transparency. These values are at the heart of Ambassador Services, and its people work tirelessly every day to uphold them.

Ambassador Services is your single source for comprehensive maintenance and ground solutions. The goal of the company is to provide an exceptional customer experience by creating inspiring spaces where teams can thrive and clients to focus on growing their business.


Through eco-innovative solutions, safe procedures, and swift communication, Ambassador Services has earned an unparalleled 95% customer retention rate and lasting relationships with the owners of more than 395 commercial properties. Ambassador Services also boasts an 82% employee retention rate, showing proof of excellence to everyone associated with the company.


Ambassador Services maintains its flawless track record by ensuring that every person, facility, and all greenery is treated with professionalism and care.


While operating Ambassador Services, Alex discovered there wasn’t a service management platform that could do everything his business needed, so he decided to create a proprietary solution. uSource is an end-to-end Enterprise Resource Planning (ERP) platform designed by maintenance industry experts with a combined 100+ years of experience. 

uSource’s goal is to empower maintenance service providers to meet their clients’ needs—from scheduling the crew to billing the client, tracking work orders, running reports, and overseeing operations in real-time.

Maintenance service companies come in all sizes. Some only offer cleaning and janitorial services, and others offer HVAC, landscaping, and everything in between. uSource can adapt to all of these different types of maintenance service models, and businesses only have to pay for who’s using the system, and what they’re using it for.

uSource is changing the future of the facility maintenance industry, making it easier for maintenance businesses to scale while improving communications, increasing sales, and promoting safe operations. It handles the details and grants business owners the ability to effectively manage their business.

The uSource team is dedicated to providing the best possible experience for users. The uSource development team continues to update and improve the platform based on feedback from its community of users.
