It's National Bosses Day! Today, we thank Mark DeLong and Vaughan Seifert for their continued leadership of Efinitytech.
Mark started Efinity in 1998 as President and Senior Programmer. Mark programmed VSM Tools, our proprietary Content Management System, which currently supports hundreds of websites.
In 2004, Vaughan became Vice President and Head of Sales & Marketing. Since then, he has been integral to Efinity's success, helping us to meet clients' objectives and deliver quality results.
Together, they have worked tirelessly to ensure Efinitytech provides superior website design, development, hosting and SEM services.
As Efinitytech approaches its 29th year in business, we reflect on the impact both of you have had. Thank you creating a culture of growth and opportunity, and a truly positive place to work!
