Lester Quinonez - President

Originally from Nicaragua, Lester Quiñonez has possessed the desire for competing, growing, and learning since he was a child. He has had a passion for playing soccer since he was 8 years old, regularly plays the guitar, and explores the outdoors whenever possible. His home country is where he studied Industrial Engineering at Central American University (Universidad Centroamericana), which was the first private university in Central America. Before starting his career in marketing and sales, Lester was a pizza chef in Miami. He made the career move because he was yearning for the chance to grow and learn in an environment that facilitated advancement and responsibility in the field of business. Working with his remarkable team and making progress each and every day are some of the reasons why Lester loves his job. Additionally, he finds great joy in working with customers. “I like to go out, make friends, and help others—this is what makes my job so special.” When he’s not working, Lester spends time with his family seeing movies and going on long walks. The little moments he shares with them are especially important to him. By the time he’s 50 years old, he wants to be a successful businessman operating internationally. Lester hopes to travel the world, spend quality time with his family, and retire with an accomplished sense of prolific success.


Mercedes Espinoza

Mercedes grew up in La Habra, CA. With an entrepreneurial spirit from the beginning, she believed that hard work and experience would get her further than an undecided major, so she jumped right into the hospitality industry and got to work. After three years, she needed a change in her life so she bought a one-way ticket to Miami, Florida. It was there that she met Quinonez Management Group’s President, Lester, and decided to help him open his firm here in Houston. She says it was an easy decision because she saw the endless opportunities that could be provided to her. “I love working here because it never actually feels like I’m at work,” explained Mercedes. “The family environment, the support that is provided, and the fact that I’m always being pushed to do more than the average person would do are a few of my favorite things about our culture,” she added. Mercedes goals are become a Millionaire by age 25, a billionaire by age 40, and create Entrepreneur schools for future entrepreneurs in third world countries. A quote that she lives by is from Grant Cardone; “what’s the Point of being alive, if you don’t at least try to do something remarkable.”


Krystal Mercado

Krystal grew up in Hartford, Connecticut where she attended Connecticut International Baccalaureate Academy. She decided that formal education was not the path for her and became a House Parent to girls in foster care. Although her work with the girls was rewarding, it was also a very challenging environment to be in for an extended amount of time. The upbeat and positive culture at Quinonez Management Group is exactly what she needed. Krystal’s drive to learn sales and become a “closer” helped her grow quickly into a valuable member of our team. She loves to dance salsa, reggae, and hip hop and admits that Cuban food and pizza are hear weaknesses. Personally, Krystal looks forward to purchasing a home and starting a family. Her professional goals include continuing to develop others, so they can be the best version of themselves while advancing her own career to leave a legacy for her family.


Frank Oscar Grass

Originally from Havana, Cuba, Frank came to the United States to study Marketing at Florida International University. Upon graduation, he started working in valet parking and quickly worked his way up to an event coordinator! His extensive background in the hospitality industry equipped him with the people skills necessary to excel in the marketing and sales industry and he proved that he was no stranger to hard work. It seemed to be a perfect match for our Management Training program. Frank says that Quinonez Management Group gave him the opportunity to reach a much larger goal than he was able to in the hospitality field; financial freedom and freedom of time. Additionally, the atmosphere, organization, planning, and character development that the we offer are a few of his favorite aspects of working here. Some other things Frank enjoys outside of work are UFC, boxing, water rafting, baseball, and kayaking. His ultimate goal is to visit all of the Wonders of The World as well as 50 additional countries.“I believe the richest man is not he who has the most, but he who needs the least.”

We are not a team because we work together.

We’re a team because we respect, trust and care for each other.
