About Modern Engineering Solutions

We built MES to replace an outdated engineering model that no longer serves clients, communities or engineers.

Our story

Not Your Grandfather’s Engineering Firm

525+ completed projects so far, with a fully remote team.

  1. The old model

    Traditional firms reward hours instead of outcomes. They overbuild to protect themselves and move slowly because inefficiency is billable.

  2. What it costs

    Senior engineers burn out on production work instead of judgment. Projects stall, costs grow and uncertainty compounds.

  3. A different model

    Michael Groselle, PE, left a traditional engineering career in 2017 with zero clients and one conviction: the industry’s standard model was broken. MES opened in 2018, built to replace it.

Modern Engineering Solutions (MES) is a licensed civil engineering design firm working in water engineering, wastewater engineering, site civil engineering for land development, and construction administration.

Leadership

  • Michael Groselle, PE, CEO and founder of Modern Engineering Solutions

    Michael Groselle, PE

    CEO and founder

    Michael is a licensed professional engineer in Texas and eight other states and a graduate of The Citadel, The Military College of South Carolina, where Michael competed as a Division I student-athlete. That experience shaped the discipline and work ethic MES runs on. Away from engineering: a three-time American Ninja Warrior competitor and a professional beach volleyball player.

    Michael runs MES on one philosophy: build systems that work, hire people who care, and deliver infrastructure communities can rely on for decades. That means growth without debt-fueled risk or burnout, and no shortcuts on technical excellence.

Why we exist

Our mission and vision

  1. Our mission

    We help developers, municipalities, utilities and engineering firms deliver water and wastewater infrastructure faster and better by combining experienced engineering judgment with modern tools, remote-first operations and a ruthless focus on what actually creates value.

  2. Our vision

    To replace Grandfather Engineering with a modern delivery model where value beats hours, AI multiplies engineers, and infrastructure gets built faster without burning out the people who design it.

  3. In practice

    Clear feasibility, clean submittals, predictable timelines and practical designs that can be built and operated. Infrastructure should not require bleeding budgets or burning out engineers.

Our values

How we price and plan

The principles that guide how we design, price and deliver work.

  1. Value over hours

    We do not price on time spent. We price around outcomes: permits secured, schedules protected, construction costs reduced and risk removed.

  2. Speed is a design constraint

    Time to permit and time to water matter as much as hydraulics and code compliance. We engineer with schedule in mind from day one, instead of bolting it on at the end.

  3. Conservative growth, aggressive quality

    We choose financial stability over debt-fueled growth, so we can protect quality and say no to work that is not a good fit. We pay our subcontractors on time, every time.

Our values

How we do the work

  1. Deep work beats busy work

    Quality engineering requires focus. We protect uninterrupted thinking time and cut long handoff chains, which means cleaner designs and fewer revisions.

  2. AI as a multiplier, not a replacement

    AI handles repetitive drafting, structure and first-pass organization. Every technical decision is made and reviewed by a professional engineer.

  3. Continuous learning is required

    We run on feedback loops, peer review and constant iteration. “This is how we have always done it” is not an acceptable answer.

What we care about

The reasons behind how we work

  1. A PE makes every call

    A licensed professional engineer makes every technical decision and reviews every deliverable before it leaves MES. We stamp only in states where we hold a license.

  2. Straight answers, even “walk”

    You get a clear recommendation, not a menu of equal options. If a site does not work, we tell you to walk before you commit capital.

  3. Less admin, more engineering

    We use AI to cut the admin. You work directly with the engineer doing the work, not a coordinator three layers removed.

  4. Your client stays yours

    When we support another engineering firm, we never contact or market to its client. A written non-solicitation is standard.

How we work

An approach built to reduce uncertainty

  1. Designs that get built

    We design for real construction conditions, not for what looks elegant on a plan sheet.

  2. Submittals that move

    Schedule is a design input from day one, so submittals move through agency review with fewer revisions.

  3. Do what we say, say what we do

    When something has to change, you hear it from us first, not from a surprise change order at month end.

  4. Systems, not heroics

    Standups, templates and tickets keep work moving and quality consistent. A 60-hour week to rescue a project is a system failure we fix, not a badge.

  • Exceptional service from start to finish. Their team understood our development timeline and worked around it. The wastewater plant design was exactly what we need and was approved on time.

    Neil Engineering · Google review

  • Modern Engineering Solutions was great to work with as we had to replace the entire water system within the MH community we own. Mike and his team performed all the engineering work necessary to get the job done. Well done!

    Michael Wallis · Google review

  • We had a great experience working with Modern Engineering Solutions on the single-family homes subdivision project. Mike and his team were very professional, cohesive, and worked well together. We were able to complete the project on time and within budget. I would definitely recommend them to anyone looking for sub division designs!
