I reached out to Dr. Lynch after there was a small fire in a home I had under renovation. The fire caused a lot of smoke and soot damage. Dr. Lynch was very helpful by explaining the options I had for environmental testing. Dr. Lynch made himself available to respond to the property to conduct appropriate testing to guide the remediation. Fortunately, I had a very responsive contractor who immediately formulated an aggressive mitigation plan, negating my need to enlist Dr. Lynch for testing. I was extremely impressed with Dr. Lynch and Environmental Safety Management Corporation. I would not hesitate to engage Dr. Lynch for all phases of Environmental testing. Thank you Dr. Lynch!

Dr. Lynch was incredibly helpful advising me how to deal with a health concern I am having at my home. I have 4 children, so I am eternally grateful for his help. He took time to clearly understand my concerns before offering me his expert advice. He is intelligent, honest and compassionate which is wonderful because these issues can be sensitive. He is also considerate in regard to saving you money, and he does not use scare tactics to get business. It is my pleasure to give him 5 stars and recommend him for all your environmental needs. He is really the best at what he does. Thank you, Dr. Lynch!

I’m so happy I contacted ESM! Dr. Lynch listened patiently as I explained about my present problem. He asked relevant questions and analyzed the situation in a systematic way. He employed a wholistic approach in order to solve the cause of the horrific smell in my house. With his help, he found the root cause. I ‘m glad that I can now safely return and live back in the house I love. Again, thank you so much for all your work. You were great. I will definitely tell others about the excellent work you do for your company.

Dr. Lynch and his team of experts partnered with us to develop safety controls and OSHA required documentation for our processes. When OSHA conducted an unannounced inspection, there were no violations…CASE CLOSED! Thanks again for all your hard work and guidance these last few years.”

Dr. Lynch came highly recommended by my contractor. He performed two rounds of mold testing—before and after black mold remediation—in my single family home. He was timely, professional, and responsive. He took his time to ensure I understood the test results and best course of action. He made himself available for questions and advice when needed. Working with Dr. Lynch gave me comfort and confidence that my home would be taken care of. I’d definitely recommend his services for testing at home or business.

Truly can't thank ESM Corp - Dr. Lynch specifically - enough, nor recommend this company highly enough to anyone in need of such a service. This business brings a wealth of knowledge to the job, with a no-nonsense "safety-first" approach and the data to back up every recommendation. Just as importantly, Dr. Lynch's leadership, SME skillset, and project management-style direction is truly comforting in, speaking from my own experience, a very emotional and vulnerable situation in dealing with the environmental safety of our home. I hope to never need to use them again (!), but if I do, I will have the peace of mind to know my home is in good hands. Thank you again for everything!!
