Rob grew up in Trenton NJ. Then, moved to Texas as soon as he could. Don't hold the NJ thing against him because he often, "knows a guy" that can be very helpful for all of us.
Rob is new to the architecture world after spending his whole career at different levels in retail operations, marketing and strategic planning.
Rob has a BA in Mathematics, a Masters in Business Administration.


A strong work ethic, an open-hearted and engaging personality, and a laugh that makes you want to smile with him; Gregory Lincoln Lake is the new Vice President of Sales at Specified Interiors.

In his free time, Gregory spends time with his beautiful family of four.  He also volunteers his time into coaching where he is a level 1 certified track & field head coach at the Northwest Flyers Track Club. He also holds a Black Belt in Karate.

Team SI

Gaynor Sherer, graduate of Texas Tech University with BS in Fashion Merchandising/Marketing, joined her father, Tony Boxell, in their family business in 2001. After spending eight years as a product development manager and material specialist for major shoe brands such as Liz Claiborne footwear and Reebok and discovering both West cost and East coast living, coming home to Texas and into the world of commercial building materials was quite a change. With her New Jersey born and raised, Italian husband and their firstborn, Gabriella, in tow, their adventure began! After 15 fantastic years working alongside her father, mentor, industry icon and hero, Tony was called to the Heavenly pastures in May of 2016 and the firm passed onto Gaynor for the next generation of the Boxell family to continue the legacy Tony Boxell began in 1980. These were huge shoes to fill and the song by none other than Gloria Gaynor “I will survive” became a theme song as the leap into business owner, personnel manager , trainer and mentor-as well as the continued role of salesrep began. With her sister, Valerie, who started in the firm two years before Gaynor, by her side, and the addition of her husband, Rob Sherer MBA, finance and business operations expert, they hired renowned business coach, John Lucas, from Boca Raton, FL and began to build a foundation for the new generation of SI. In 2017, Gaynor “stepped it up a notch” with the addition of Gregory Lake AIA, a 19yr experienced Senior Associate/Project Architect and Project Mgr from HOK with the goal to add back the technical knowledge of design and construction that was so innate in Tony Boxell and a key reason SI carries the reputation as a product consulting firm rather than sales agency. Shortly after Gregory’s arrival, came Jeni Beecher, Executive Assistant and “team Mom” to make sure all the work family has what they need each day! And finally, Alex Jones, Estimator and UH student joined the team.  After a challenging and busy year of change in 2017, Gaynor has acquired a solid “A” team and Specified Interiors is poised to reach new heights in their product consulting, marketing and design support for the A&D and contracting community of South TX! 
Gaynor and Rob live in Cypress, TX and have a daughter, Gabriella and son, Tony, who both attend the same school she graduated from, Cy-Fair High School. In her free time she enjoys traveling with her family (Cabo San Lucas and Colorado are favorites), bay fishing, volleyball and enjoying the outdoors!

Alex was born and raised in Kingston, Jamaica, up until he graduated High School in 2013. He then moved to Houston, Texas to pursue his college degree. In 2016 he graduated from college with an Associates Degree in Architectural Engineering. Outside of work Alex keeps himself busy with volunteering at church, as a teacher to the youth group and with the Audio and Visual team. With his free time he enjoys playing pool, soccer, hiking, traveling and anything outdoors.
