ALFONSO C. TELLO, P.E., P.L.S.
of Counsel

Vietnam veteran, Mr. Alfonso C. Tello was hired at Schwebke-Shiskin & Associates (SS&A) as a Party Chief in 1969 after his outstanding topographical surveying with the US Marine Corps. By 1974, Tello’s field experience and educational background propelled him to become a staff engineer responsible for the design of drainage, water, sewer, and paving infrastructure for large public and private developments.

Tello’s determination and persistence warranted exponential growth for both the company and himself. He became an assistant vice president and engineering project manager of SS&A by 1977. Consequent to this, he was branded an expert in the area of stormwater management and was directly involved with the development of criteria and standards for the South Florida Water Management District, as well as Broward County’s Drainage Districts.

By 1982, Tello was licensed as both a Professional Land Surveyor and a Professional Engineer in the State of Florida. Tello’s diversified experience in both surveying and engineering has been an integral part of his personal success and an invaluable asset to the success and growth of SS&A.

As the majority stockholder and President since 2006, he has strived to continue the legacy and vision that his predecessors began in 1947.

Principal

Mr. Mark S. Johnson joined Schwebke-Shiskin & Associates (SS&A) in 2003 as a Vice-President and Project Manager of the Surveying Department with more than thirteen years of experience as a Professional Land Surveyor. In 2006, he became one of three principals and adopted his current title of Secretary-Treasurer. As such, he is responsible for all surveying operations and personnel management within the company. Johnson has vast experience and knowledge in platting within Miami-Dade and Broward. Not only is Johnson a proven Land Surveyor, but his physics degree from Florida State University in 1987 and his aggregate of knowledge of land development makes him one of the company’s greatest assets with respect to surveying, engineering, land planning, and general construction.

HERNANDO J. NAVAS, P.E.
Principal

Mr. Hernando J. Navas graduated from Florida International University in 1990 with a bachelor’s degree in civil engineering.

Just four years later, Navas became a licensed professional engineer in the state of Florida. As such, he has led projects all across South Florida, the Caribbean Islands, and parts of South America. Achieving his current position as Executive Vice-President in 2006, he continues to work towards developing the company.
