Mark Friesen

Master Plumber, Owner

Mark Friesen, master plumber and owner, has over 25 years of experience in the plumbing industry. He completed a five year apprenticeship and worked as a journeyman plumber on commercial jobs until he achieved his master’s license and started Southside Plumbing.

Some of the projects he has worked on for other contractors include Skyridge Medical Center, Cherry Hills Community Church, and Park Meadows Mall. For Southside Plumbing he has built custom homes, run underground utility lines, and currently focuses on residential repair.

Mark is also a devoted husband and father. (It’s true! This is written by his wife of over 20 years.) He enjoys serving at his church, outdoor sports, and spending time with his children Elena, Christina, Micah, and Isaiah.

Due to popular demand, I have kept Mark’s experience from New Orleans on the site, click here to read more.

During his apprenticeship through the PHCC-NV, he placed 1st in a local PHCC plumbing competition, moving on to place 4th in the PHCC national competition during his 4th year. After completing the apprenticeship and obtaining his master’s license, he partnered with his parents at Aqua Plumbing, where he was part owner until he relocated to Denver, CO. Now the newest member of Southside Plumbing, Trevor is happy to service all of our amazing customers.

Trevor is married to his beautiful wife Kayla and is a proud father to 3 boys: Grayson, Landon, and Zaron. They enjoy family hikes with their dog Blue, snowboarding, soccer, and simply enjoying the outdoors.

Kyle has been with Southside Plumbing for over 2 years and is not new to construction. He has spent time in landscaping, civil construction, and some light home construction. He started off at Southside Plumbing as a plumber’s helper part time, but enjoyed the work. After 2 years as a full time apprentice, he is now a licensed residential plumber and works with our master team as he increases his knowledge of the trade and pursues his journeyman license.

Kyle enjoys camping, dirt biking, video games, and playing with his dog Scooter.



Maria Hawthorne

Apprentice Plumber

Maria is a renaissance woman who made a career change from the landscape design/horticulture and interior design industries to pursue plumbing. She recently joined Southside Plumbing after having worked the first three years of her apprenticeship in commercial construction. She is excited to broaden her plumbing knowledge and master the plumbing trade.

Maria is a mom to two grown children (one of them a plumber!) and a mischievous lab, Whiskey. She enjoys cooking, traveling, and hiking with her husband.


Liz Friesen 
& Kara Lewis

our office team

Liz started off her career in Corporate America, but left to start a family. She has a bachelor’s degree in business and decided to use it to start a plumbing company with Mark, her husband and the head master plumber. During her journey with Southside Plumbing, she pursued a master’s degree in English and taught English composition at the University of Colorado. Even though she loves academia, Southside Plumbing needed more and more of her time, so she left to dedicate her time to Southside.

Liz enjoys playing the flute, supporting children in music, writing stories, and reading creative non-fiction. She and Mark spend their free time together enjoying each other’s company.

Kara Lewis is an out of the box professional with a degree in fine art from Michigan State University. She moved to Colorado in 2014 and currently enjoys working for Southside Plumbing as their Creative Sidekick Extraordinaire. Yes, that is her title, as she does a little bit of everything including (but not limited to) design, organization, inventory and building. Kara believes the greatest thing you can do for your employer (and yourself) is to accomplish something every day and do it with pride. Before joining the Southside team she worked in Community Relations, branding, designing, promoting and organizing internal and external volunteer events that consisted of small one hour events, to nationwide partnerships with over 30 non-profits. This dedication brought her various awards such as Corporate Volunteer Council of Atlanta’s (CVCoA) Community Relations Program of the Year, CVCoA Volunteer of the Year, and International Association of Business Communicators of Atlanta’s PR and Employee Communications Social Responsibility Campaign.

In her personal time Kara enjoys spending time with her husband, daughter and friends enjoying all that Colorado has to offer.


Southside Plumbing was started in 2005 as a home based business in Highlands Ranch by Mark Friesen and his wife and office manager Liz Friesen.  Southside started off building custom homes, but as the recession slowed the home building industry, Southside began taking on residential repair plumbing in 2007-2008.

Our team at Southside Plumbing is a close group of plumbers who are always striving to keep on top of the newest breakthroughs in the industry.  We don’t stay in the past, we are advancing towards the future and finding new ways to keep your home comfortable and safe.
