"I have recommended John M. O’Reilly to my clients over the past fifteen years. They have provided my clients with excellent service including Title V septic inspections, septic system design, bidding and construction oversight, retaining wall design, bluff oceanfront site plans and meeting with conservation administrators and commissions. John and his staff have always worked hard and communicated very well with my staff. We will continue to have our clients use their services."
