Our Story

2019

In 2019, Mike and Suzanne Lynn purchased Joiner Micro Laboratories from the Joiners. Under their leadership, the laboratory became part of a comprehensive group of companies providing environmental, septic, wastewater, well-water, and laboratory services throughout Virginia. Mike and Suzanne remained committed to preserving the trusted name, values, and personal service on which Joiner Micro Laboratories was founded while creating new opportunities for the company and its employees.

2025

In 2025, Seekye Capital purchased a majority interest in Joiner starting an exciting new chapter. Seekye's mission is to guide seamless business transitions that preserve what makes companies unique like their vision, values, and legacy. Inspired by Matthew 6:33—"But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you"—Seekye's name reflects their commitment to Christ-centered values, integrity, and respect in every partnership. They are providing additional resources, mentoring and opportunities for continued growth while preserving our experienced teams, trusted service, and longstanding community relationships.

Today

Today, Suzanne Lynn continues to serve as General Manager of Joiner Micro Laboratories, providing experienced leadership and ensuring continuity for our customers and employees. Her ongoing involvement helps preserve the personal service, strong relationships, and commitment to quality that have long defined the laboratory.

Accurate Testing. Trusted Results.

Joiner Micro Laboratories provides private well and drinking water testing, public water compliance testing, wastewater testing, bacteriological analysis, and other environmental laboratory services. We follow state-approved analytical methods and perform all required quality-control checks in accordance with Virginia standards to maintain confidence in the accuracy and integrity of our data.

More Than Numbers on a Report.

We understand that laboratory results are more than numbers on a report. They can help protect a family's drinking water, keep a project moving, support environmental compliance, or ensure the proper operation of a public water or wastewater system. Our knowledgeable team takes the time to answer questions, explain testing options, and help customers select the appropriate analysis for their needs.
