Alliance Environmental Group names Tony Witter SVP of Sales and Stephanie Mitchell VP, Corporate Controller, to strengthen West Coast operations.
AZUSA, CA, UNITED STATES, September 22, 2026 /EINPresswire.com/ — Alliance Environmental Group, one of the leading environmental and indoor air quality services companies on the West Coast of the United States, today announced the appointment of two senior executives: Tony Witter as Senior Vice President of Sales and Stephanie Mitchell as Vice President, Corporate Controller. The appointments bring more than three decades of environmental services sales leadership and deep multi-industry finance expertise to a company that completes more than 2,000 environmental remediation, abatement, and indoor air quality jobs every month across California, Arizona, Nevada, and Washington.
The two hires are part of Alliance Environmental Group’s ongoing effort to improve and expand operational excellence across its 14 service markets in the western United States. As demand grows for environmental services — including asbestos abatement, lead abatement, mold remediation, indoor air quality testing and remediation, fire life safety, and post-fire cleanup — the company is investing in the commercial systems and financial infrastructure needed to deliver consistent, scalable results for commercial and residential clients.
Tony Witter, Senior Vice President of Sales
Tony Witter brings more than 30 years of experience leading multi-state sales, business development, and operations organizations across the environmental services, environmental remediation, and industrial sectors. His career has focused on driving sustainable growth, developing high-performing sales teams, and building the commercial systems needed to scale environmental services operations. At Alliance Environmental Group, Witter will lead the company’s sales organization with a focus on expanding market opportunities, strengthening customer relationships, and supporting long-term growth across all regions served by the company, including California, Arizona, Nevada, and Washington.
“Alliance has built an exceptional reputation over three decades by doing the work right and standing behind it,” said Witter. “My focus is to make sure our commercial teams and systems match that standard — so every property manager, contractor, and claims professional we serve gets the same reliable, responsive experience in every market.”
Stephanie Mitchell, Vice President, Corporate Controller
Stephanie Mitchell brings extensive accounting and finance experience across the manufacturing, construction, medical, and service industries, with expertise in cost accounting, project accounting, financial reporting, and leading cross-functional finance teams. Mitchell holds degrees in Business Administration and Business Management, an MBA, and a Master of Science in Accounting from the University of Phoenix. At Alliance Environmental Group, Mitchell will oversee corporate accounting and financial reporting, with an emphasis on project-level visibility and the reporting discipline that supports the company’s proprietary Quality Control Program.
“Operational excellence starts with clear, accurate numbers,” said Mitchell. “In a project-driven business like this one, strong project accounting and reporting give our field, and leadership teams the visibility they need to make good decisions quickly. I’m excited to help build that foundation as Alliance continues to grow.”
“Tony and Stephanie each bring exactly the kind of experience we need as we scale,” said Alex Young, Vice President of Marketing at Alliance Environmental Group. “Tony has spent his career building sales organizations in the environmental services industry, and Stephanie has led finance teams in some of the most demanding project-based environments. Together they strengthen the operational backbone that lets us keep our promise of timely response and quality work in every market we serve.”
