Lee Steneken - CEO - Esco Optics

Lee Steneken

Owner & CEO

As a kid, Lee grew up in the family business running around the shop. He ran a couple of machines, even worked at Esco part-time when he was in high school.  However, wanting to pursue other avenues in life, Lee attended Suffolk University in Boston and graduated with a marketing degree in 2001. After college, Lee started working for a local brewery.  It wasn’t until his dad called him and said he was contemplating retirement that Lee thought he would give the family business a shot.

He took a leave of absence from the brewery and moved back down to New Jersey.  One of his first positions at Esco was writing the instructions for each job that went out on to the shop floor. In order to do this, he went around to every employee in the stage of the process and asked them what they did and how they did it. Gaining a deeper understanding for the optical process and how optics were made, Lee quickly decided that the optical industry was where he belonged!

Throughout Lee’s tenure at Esco he has had many jobs.  From marketing to sales to shop manager to eventually president and part owner in 2011. Lee worked hard to learn the family business from the ground up. He says his greatest accomplishments come when his employees and customers succeed in their endeavors.

Lee has made a big splash in the optics industry. He has turned a small shop in New Jersey in to one of the top optical manufacturing facilities in the country. Being a member of OSA, SPIE and most recently elected to the APOMA board, Lee is always looking at ways to further Esco and the optical industry as a whole.

Outside of Esco he enjoys fishing, boating, skiing and spending time with his family.




John Escolas

Chief Operating Officer

Esco Optics is very proud to have John Escolas leading our shop. John is no stranger to operational growth and structure, and he has a proven track record with taking companies to the next level. 

John spent the early part of his career as a hands-on engineer, focusing on process improvements. While moving into more challenging roles as he advanced in his career, he learned the importance of collaborative and cohesive manufacturing amongst team members. Communication, goal setting, and cross-training became necessary characteristics in order to maintain successful growth.

Prior to Esco, John has been an integral team member of other exceptional optics manufacturers. From Machine Operator, to Director of Operations and Engineering, to Sales Manager, John has experienced all facets of a precision optics manufacturing company. These various responsibilities and positions allowed John to understand what it means to truly service the needs of a customer, and produce superior optical components.

As Esco Optics’ Chief Operating Officer, John’s role goes well beyond process and employee improvement. He is ensuring that we exceed customer expectations from the project qualifying stage through product completion and the end-user’s successful execution. He continues to improve our daily operation efficiencies while keeping the shared vision of the company in mind, that our success is based on the success of our customers. 

Outside of the office, John enjoys spending time with his wife and two children. His hobbies include all things motor driven, and you can frequently find him under the hood of a car or on his motorcycle. 


William Hill - Business Development - Esco Optics

William Hill

Sales Engineer

Bill is a University of Maine graduate and 25 year veteran of the optical industry. Throughout the years, he’s covered many facets of optical manufacturing including, glass blank machining, precision lens and window polishing, as well as, the application of metal and dielectric thin film coatings. Bill is experienced in optical properties and current metrology techniques. He has a complete understanding of optical component processing from estimating, through production to final inspection.  

As a sales and business development engineer, he’s assisted companies worldwide and has logged nearly enough miles in support of his customers to have traveled from the earth to the moon and back again.  Whether promoting single, off-the-shelf replacement parts, or optics for large-scale OEM instrument production, there are few industries he has not explored.

A country boy at heart, he resides in Southern Vermont, tucked in the hills near the Green Mountain National Forest and when not assisting customers with their optical requirements, he can be found outside, very late at night, staring up at the sky through his telescope.
