Here’s what we look like:

Avi Gottlieb,  President and Founder


In 1991, Avi founded Avcon Construction, not only because he wanted to be the boss.  Avi’s passion for efficiency, quality and transparency in the construction world drove him to realize that there is a better way to get from A to B.  And, he wanted to be the boss.  Initially, implementing his systems meant doing it all - from sales to estimating and project management.  As the company matured, “Coach” has taken more of a “behind the scenes” approach, allowing highly qualified individuals deal with daily issues while always willing to assist in more sensitive or technical issues.

Avi’s “rock” is his beautiful wife of over 30 years.  His three grown children are all successful and smart enough to be pursuing careers outside of construction.  They enjoy outperforming their dad on the ski slopes and in the gym.  In his spare time, Avi enjoys a variety of sports, as well as travel and classical music.


Nick Rizzotto, Project Manager


Nick has been flying under the radar since joining Avcon in 2001.  Left to his own devices, “Stealth” will resolve an issue before you even know there was one.  His success is gauged by the quality of his finished product and consistently meeting deadlines.  Nick obtained a diploma in Architectural Technology from George Brown College.  He is blessed with a lovely wife and two wonderful daughters.  In his spare time, Nick spends it with his family and enjoys playing volleyball and ball hockey.

Ellyn Kaufman, Facilities Manager

"Good Cop"

Our “good cop”, (ok, sometimes she’s the bad cop) keeps our various properties and businesses happy and under control.  Ellyn joined Avcon in 2009 and quickly proved herself capable of greater challenges.  As the company and its portfolio grows, Ellyn takes on a more significant role.  Ellyn holds a Bachelor degree in Arts and Education from York University.  In her spare time, she enjoys taking classes at the gym, travelling and entertaining friends and family. 

Reza Dehghan, Project Manager


Reza joined the Avcon Team as a Project Manager in 2019. He arrived with an impressive international construction background and wasted no time successfully implementing his skills on some of our more challenging projects.

Reza has earned his nickname ‘Silk’ because of his ability to smooth over rough situations with a positive, friendly approach.

In his spare time, Reza likes to spend time in the gym and from time-to-time enjoy a nice cup of coffee with friends.

Lisa Russell, Project Coordinator


When you think of tenacious, as Project Coordinator at Avcon, Lisa never gives up – ever. She’ll do whatever is necessary with her persistent determination and enthusiasm to accomplish a goal and she’ll do it with a sense of humour too.

Lisa has a past education with The Royal Conservatory of Music, a background in working with consulting engineers and speaks conversational Spanish. In her spare time she enjoys spending time with family and friends, photography, and of course, singing karaoke.
