Meet Our Team
Jason W Gage
Born and raised in Chico, CA, I embarked on a quest for knowledge at CSU Chico, where I earned my degree in Social Science in 1995. The allure of San Diego beckoned, and in 1997, I made it my home—a sun-kissed paradise that stole my heart during a summer visit. My journey led me to the world of window and door replacements in 1998. There’s magic in transforming houses, and I thrive on the gratitude of homeowners who cherish our craftsmanship.
In 2004, destiny smiled upon me—I met and married a fellow San Diegan. Together, we’re raising two amazing kids and sharing our lives with an adorable Pug.
Life’s a canvas, and I’m painting it one home improvement project at a time.
Mason Shepard
Sales Manager
I’m a 3rd generation San Diegan that graduated from Christian High School in 1997 and San Diego State University, with a Bachelor of Science Degree, in 2003. I have a passion for team sports and have coached football at the varsity high school level off and on for the better part of the last 2 decades. I have lived in the East County my entire life and have been in the window and door business for about 20 years. I have been the Sales Manager with JWG Windows & Doors, Inc. since 2016. I pride myself on being there for my customers by providing unparalleled customer service regardless of the size of the project. I simply treat my customers how I would like to be treated.
Jennifer Serrano
Sales / Production
A California native, I embarked on my career a decade ago in the window treatment industry. About 5 years ago I transitioned over to the construction side, bringing my passion for efficiency and innovation along. I specialize in vinyl windows and door replacements, where I weave practicality and aesthetics into every project. In 2023, I found my home at JWG Windows & Door, where I focus in sales and production. I thrive on the field, connecting with homeowners, understanding their needs, and curating tailored solutions. I’m fluent in both English and Spanish. Efficiency is my goal, the satisfaction of helping clients find the perfect fit fuels my drive. When I’m not transforming spaces, I can be found chasing sunsets.
Nicholas Gombold
Sales Representative
As a Sales Representative at JWG Windows and Doors, I bring passion and dedication to every interaction. Born and raised in sunny San Diego, I have a deep connection to the local community. After graduating from San Diego State University, I ventured into the fitness industry, where I honed my communication skills and commitment to excellence. My journey took an exciting turn when I joined the JWG family in 2018. As a former college football player and high school coach, I understand the value of teamwork and persistence. Now, I channel that same energy into helping homeowners find the perfect windows and doors for their spaces. From initial consultation to final installation, I’m committed to making the window and door selection process seamless and enjoyable.
Timmy Torres
Office & Warehouse Manager
Born and raised in the Bronx, New York from the bustling streets to the vibrant culture, the Bronx has shaped who I am today. I proudly served as an intelligence analyst in the United States Marine Corps. The discipline, camaraderie, and unwavering commitment I experienced during those years continue to resonate within me. Since 2017, I’ve been an integral part of the team at JWG Windows and Doors. As the office and warehouse manager, I orchestrate the behind the scenes magic that keeps our operations running smoothly. From coordinating shipments to ensuring impeccable inventory management, I thrive on the details. I believe that every interaction is an opportunity to create a positive impact. Whether it’s answering inquiries, resolving issues, or going the extra mile, I take pride in leaving a lasting impression and paying attention to detail.
