A Letter from the President

Hello, my name is Sean Mullarkey. I am the founder of TriState Water Works. I have been in the horticultural industry my entire life, and have been designing and servicing irrigation projects for over 25 years. My certifications include: Certified Irrigation Designer, Certified Irrigation Contractor, Certified Landscape Irrigation Auditor, Certified Golf Irrigation Auditor, EPA Water Sense Partner, and Certified Rain Exchange Professional.

I decided to start TriState Water Works while I was working as the territory manager for a major irrigation wholesaler. I saw how contractors were treating their customers by providing poor service. I could not understand how contractors could be hours late for appointments, take days to return phone calls, have to make several appointments to fix a single problem and call themselves professionals. I want to make a difference; we have a live person answering the phone during working hours, all phone calls will be returned in one business day, 90% of service calls will be handled on the first visit, and we will arrive promptly for our appointments.

Conservation is a primary objective for TriState Water Works.  Wasted water is not acceptable for many reasons. Water is a finite resource, less than one percent of the earth’s water is available for consumption. We are blessed in the Greater Cincinnati area to have an abundance of water while other areas of the world are having a water crisis.

I would love to hear from you about how we can help you with your water conservation or ideas you have for doing the same. Please follow me on my blog “The Water Spout” and join the community. I look forward to your comments.

About Our Team

Summer Pelfrey

Summer Pelfrey

I started with TriState Water Works in March 2016, in the role of Office Manager. I love working with the company, especially developing relationships with clients and helping them with appointments and questions. Hopefully, you have called in and spoken with me on the phone already!

In 2014, I completed my Bachelors in Science Management degree and am currently working towards my PhD in Organizational Leadership. Prior to working with TriState Water Works, I operated my own in-home care practice for seniors, specializing in memory care.

Off the job, charity work is my passion. I participate in motorcycle rides to raise money for organ donor awareness and send two or three children to camp for cancer patients each year. As a member of the Elks, I help with their home for troubled boys, along with volunteering for the Army/Navy games and organizing events for patients of the VA hospital.

I have been with TriState Water Works since July 2013. I am a Certified Irrigation Technician. During college, I worked for the Blue Ash Park District, and I graduated from Cincinnati State with a degree In Turf Science- Agronomy. I have also worked as a Golf Course Assistant. I am very interested in irrigation and am pleased to further my career in the field through my work with TSWW.

I enjoy working in irrigation because I like to solve problems and make people happy. Customer service should not be taken lightly, and when I leave a customer’s property, I strive for each customer to want to use our services for years to come.

In my spare time, I like to golf, attend Reds games and look at my massive collection of baseball cards. My wife and I are proud parents of a little girl.

My career with TriState Water Works started in March 2018, when Sean hired me after graduation from Cincinnati State. I began to enjoy irrigation work during my internship at Camargo Club. During my final semester, Sean taught an irrigation class that really sparked my interest in the field, and I knew I wanted an irrigation career.

I earned two Associates degrees, Landscape Horticulture and Turf Grass Management. And, I am a Certified Irrigation Technician. I’m a people person and enjoy helping clients solve problems.

Beyond work, my fiancée and I have two daughters. Being a full-time student and full-time dad was a challenging time in my life, but it was worth it for my career opportunities. We love watching our daughters play softball and soccer. I enjoy being outdoors and love hunting and fishing.
