What's New

Project Coordinator

Karen Sewell is a dedicated Project Coordinator at ONE Environmental Group whose warmth, work ethic, and three decades of administrative and accounting experience make her an invaluable member of the team. Karen joined ONE in July 2025, assigned to the Midlothian office and she also supports ONE leadership in the Tidewater region, offering a seamless extension of the team wherever she is needed.

Karen’s professional journey began at Avis Budget Group, where she embraced the company’s “We Try Harder” spirit. That mindset guided her through nearly 30 years with Avis Budget Group, where she advanced into roles involving revenue accounting, financial reconciliation, collections, customer relations, and team leadership. She later brought that expertise to Arrowhead Environmental Services and Superior Environmental Solutions, managing complex billing operations, ensuring payroll accuracy, coordinating collections, supporting compliance processes, and building strong relationships with customers and vendors.

At ONE, Karen supports project managers by preparing billing, coordinating project activities, conducting research, communicating with customers, and stepping in wherever help is needed. What she appreciates most about working at ONE is the sense of teamwork and shared purpose. “It’s one group, one team,” she says. “I really appreciate the commitment of the people here, and I respect the company’s involvement in the community.”

Service plays a central role in Karen’s life outside of work as well. She has volunteered with the Windsor Lions Club for more than a decade and currently serves as its Treasurer. She is active in the Women’s Club of Windsor and contributes to multiple volunteer efforts through her church. When she finds free time, she enjoys biking, kayaking, and vacationing in warm places. At home, Karen and her husband, Charles, have been married for 26 years, and their family includes six children and fifteen grandchildren. They share their home with two Yorkies, Boomer Kai and Libby Jean.

Senior Project Manager

When Senior Project Manager Brian Winkler, P.E., joined ONE Environmental Group in September 2025, he brought with him more than 20 years of experience in the environmental industry supporting engineering, project management and client development – along with a passion for family, community and problem solving. Based in Warrington, Pennsylvania, Brian is spearheading the firm’s efforts to establish a Philadelphia office and strengthen ONE’s presence across the Northeast.

A Penn State graduate and licensed Professional Engineer in multiple states, Brian’s career has been defined by technical versatility and leadership in complex environmental projects. Prior to joining ONE, he managed a wide range of industrial facility projects, actively partnering with clients to maintain compliance with air, waste and water regulations under federal, state and local programs. His work has included developing and implementing compliance strategies for manufacturing, energy and waste-to-energy operations, as well as conducting multi-media audits, managing permitting processes and overseeing environmental reporting and training programs.

Brian also has experience managing waste-to-energy facilities where he directed day-to-day compliance programs and coordinated with regulatory agencies to ensure continuous operational integrity. His hands-on approach and deep regulatory knowledge have made him a trusted advisor to industrial clients navigating complex permitting and compliance challenges across multiple jurisdictions.

Brian was referred to ONE from a satisfied long-term ONE client and drawn further to ONE after learning about the company’s collaborative culture and steady, values-driven growth.

Outside of work, Brian’s world revolves around his family. He and his wife are raising three children at their home in Warrington. They spend time involved in youth sports and activities, gatherings with family and friends, and local community events.  Together, they founded an Outreach Bag program through their church to support homeless and less fortunate children and adults. Once a month, the program organizes volunteers to assemble bags filled with food and toiletries for those in need.

When he’s not leading environmental projects or giving back to his community, Brian enjoys spending time at home with his family, playing basketball and getting out on the golf course when time allows. He’s also known for his curiosity and persistence, whether it’s tackling household projects, learning to solve a Rubik’s Cube or increasing his green thumb with a home garden – all fitting traits for someone who thrives on tackling complex challenges from every angle.

As ONE expands its reach in the Northeast, Brian Winkler is helping ensure the firm’s reputation for technical excellence and personal service continues to grow, one project, one partnership and one community at a time.

Environmental Consultant

Eli Pfadt didn’t set out to work in environmental consulting, but we’re glad the path led him to ONE Environmental Group.

Based in ONE’s Midlothian, Virginia, office and living in downtown Richmond, Eli joined the firm in June 2025 as an Environmental Consultant. He brings a background in safety and a fresh enthusiasm for environmental work that’s quickly made him a valuable member of the team.

Originally from Erie, Pennsylvania, Eli graduated from Slippery Rock University with a degree in safety. Before joining ONE, he worked at a firm serving as a general contractor for Dominion Energy. While he enjoyed his previous role, Eli was ready for a change, and when the opportunity at ONE arose, he jumped in. “The vibe here is special. I’d gotten to know some people at ONE already, and I really liked what I saw.”

At ONE, Eli helps clients stay in compliance with environmental regulations while contributing to projects that make a real-world impact. His certifications include HAZWOPER, as well as erosion and sediment control and stormwater licenses from the Virginia Department of Environmental Quality (DEQ). He also holds Resource Conservation and Recovery Act (RCRA) certification.

What stands out most to Eli about ONE? The culture. “I like how supportive everyone is,” he says. “People here are really friendly, always willing to help, and it’s just a good atmosphere.”

Outside of work, Eli enjoys exploring his relatively new home base of Richmond. A resident for only a few years, he’s still uncovering all the city has to offer. He also enjoys kayaking, golfing, and spending time with his dog and cat.

Whether he’s in the field supporting clients or on the river taking in the views, Eli brings a calm and steady approach to everything he does, and ONE is glad to have him on the team.

Environmental Consultant

When Brock Showers joined ONE Environmental Group, he was ready for a change and excited for a challenge. After several years focused on landfill monitoring and reporting, Brock sought broader opportunities to grow his environmental expertise, and ONE’s collaborative, multidisciplinary approach was a perfect fit.

Based out of ONE’s Midlothian office and living in Richmond’s historic Church Hill neighborhood, Brock serves as an Environmental Consultant, specializing in SPCC and SWPPP audits and inspections. He’s also HAZWOPER 40 certified and currently pursuing his Erosion and Sediment Control Inspector certification with the Commonwealth of Virginia.

Before joining ONE, Brock worked with LaBella Associates, where he handled groundwater monitoring, landfill gas reporting, and leachate sampling. While the experience was valuable, Brock knew he wanted to expand his skillset. “At ONE, I get to be part of a team that touches so many different areas,” he says. “There’s always something new to learn, and everyone here is incredibly friendly, knowledgeable, and willing to help.”

A native of Fredericksburg, Virginia, Brock moved around a bit with his military family. He graduated from the University of Virginia in 2019 after starting his college career at the University of Alabama. He played rugby in college, lacrosse in high school, and even spent time coaching youth lacrosse in Austin, Texas, from 2019 to 2022.

Outside of work, Brock enjoys golfing, hiking, and playing pickleball. You might spot him and his girlfriend exploring the Virginia Museum of Fine Arts or browsing a local farmer’s market on the weekend. He’s also a proud cat dad to two cats and has a twin brother who’s soon relocating to Mexico.

With his curiosity, team spirit, and eagerness to grow, Brock is a great addition to the ONE family, and we’re excited to see where his journey leads next.

Senior Health and Safety Director

As Senior Health and Safety Director at ONE Environmental Group, Richard Joye brings a wealth of experience and a heart for service that aligns perfectly with our mission. He is based in Lexington, South Carolina and supports ONE’s Mid-Atlantic operations while also helping expand our internal and client-facing Health and Safety services.

Originally from Orangeburg, SC, Richard started his career serving in the U.S. Air Force. After transitioning to civilian life, he worked in a chemical plant where he rose from filling drums to becoming a certified chemical process technician. It was during this time that his passion for safety took root. After volunteering with a local fire department and becoming a fire service and EMS instructor, Richard pivoted his career toward EHS, taking on leadership roles at major companies like Michelin, Honda, Ingersoll-Rand, and FN America.

 Richard’s connection with ONE began during his time at FN America, where he worked with the company as a client. That relationship opened the door to a new opportunity. “ONE was looking to expand their internal health and safety program,” Richard explains. “I was excited about the chance to help shape and grow it.”

Today, Richard plays a dual role at ONE: guiding our internal health and safety initiatives while also working with clients to offer health and safety consulting services. With certifications that include Master Certified EHS Manager, Psychological Health and Safety Manager, Certified Ergonomic Evaluation Specialist, and multiple OSHA credentials, Richard brings top-tier expertise to the role.

But it’s not just his credentials that make Richard a valuable part of the team. It’s also his character. “What I like best about working at ONE is the people,” he says. “Their attitude didn’t change when I went from being a client to being a team member. They’re just a good group of genuine people who want to help in the most sincere way.”

Outside of work, Richard is just as active. A lover of all things water, he enjoys boating and scuba diving — a hobby he’s pursued since the late ’90s, with dives all over the Caribbean and Gulf. He hopes to one day explore the Pacific and the Great Barrier Reef. He’s also deeply committed to his church, volunteering for mission trips, oil change ministries for widows, and serving on the church safety team. He’s also an avid cook, especially when it comes to grilling or griddle cooking outdoors.

Richard lives with his wife of 15 years, and they have two daughters and two grandsons. Their family also includes two rescue pups, Jack and Maddie.

We’re proud to have Richard on board as we continue to grow our Health and Safety  services and foster a culture of safety, both within our own team and for our clients.
