Kamadulski Excavating & Grading Co, Inc. was founded in 1958 by Leo and Fannie Kamadulski. The Kamadulski family owned and operated the company until Leo and Fannie’s son, David Kamadulski, sold the company in 2019. The mission of the Kamadulski family was to deliver quality service to their customers at a fair price. Ryan Fischer and Mark Crays joined the company in 2013. Ryan and Mark purchased stock in the company in 2015 and completed the purchase in 2019. In 2021, the current ownership group rebranded the company as KAMEX.
KAMEX has become an industry leader in the St. Louis Metro East. The company continues to expand into new sectors, including Commercial Warehouse Infrastructure, Environmental Landfill Cell Construction, Federal USACE Projects, Heavy Highway, Large Scale Transmission Water & Sewer Mains, Industrial, Mechanical, and Residential Subdivisions.
Strong values of hard work and lasting relationships continue to define our culture. We work together as a team, supporting and encouraging each other. We have created an environment that values success in terms of relationships and results. Our mission is to offer our customers a quality experience and our staff an outstanding place to work and build their own legacy.
KAMEX for a Cause
KAMEX FOR A CAUSE exists to strengthen our community and to improve the lives of those who live and work in the areas where we do business. We strive to get involved to support charitable efforts to provide a meaningful impact by supplying financial assets in our community. Over the course of the last few years, KAMEX has donated to the following groups: Big Brothers Big Sisters, Black Widows Softball, Pedal The Cause, Party at the Beach – Village of Pontoon Beach, Alton/Wood River Sportsman Club, CF Gateway Foundation, Gillespie Bass Club, Gillespie Masonic Lodge, and the Cystic Fibrosis Foundation.
At KAMEX, we feel that it is important to give back to our community and support the community and family members who make us a successful and striving business.
The Alton-Wood River Sportsmen’s Club
The Alton-Wood River Sportsmen’s Club is located in Godfrey, IL and provides a clean comfortable facility where members, family and guests may affordably engage in activities in a wholesome environment which encourages social activities and friendly competition. We give families equal opportunities to gain personal skills through participation in fishing, hunting and other outdoor activities.
Cystic Fibrosis Foundation
The Cystic Fibrosis Foundation is a 501 non-profit organization in the United States established to provide the means to cure cystic fibrosis and ensure that those living with CF live long and productive lives.
Pedal the Cause
OUR MISSION is to provide critical funding for cancer research at Siteman Cancer Center and Siteman Kids at St. Louis Children’s Hospital through our annual cycling challenge. It is our hope that research funded by Pedal the Cause will ultimately lead to a cure for cancer.
Founded in 2009 with the bold model of using 100% of public donations to fund world-class cancer research, Pedal the Cause has quickly become the gateway to curing cancer – all cancers, for everyone. In this period of diminished federal funding where support typically gets funneled to already proven concepts, many potential new ideas are not deemed eligible. Pedal the Cause donations “seed” best-in-breed ideas at our beneficiaries to allow the cultivation of proof of concept and critical data. These seeded projects often turn into groundbreaking results that lead to new treatments and cures, preventions, and early detection diagnostics. Additionally, donations from Pedal the Cause make a positive economic impact in the St. Louis community as stronger research funding will continue to support this high profile and critically important segment of the St. Louis economy.

The Kamadulski jobsites are typically a challenge for mobilization and setup of our cranes, but their managers and field crews always take the time to listen to our requirements and implement the necessary site preparations before our arrival. This translates to a safer and more efficient time on the job for us, which is beneficial to all involved. It’s always an honor to have the opportunity to work with the professionals at Kamadulski.
