Priscilla Foster
Priscilla Foster founded Deep Dive Plumbing Maryland after experiencing firsthand how difficult it is to find a plumber you can actually trust in Southern Maryland. She built the company she wished had existed — one that tests before it treats, diagnoses before it replaces, and tells customers the truth. Today she leads a team of six licensed professionals serving all of Calvert County and Anne Arundel County.
Why Priscilla Built Deep Dive
Every business has an origin story. Priscilla's is one that most Southern Maryland homeowners will recognize.
The Problem She Experienced
Years ago, Priscilla's own home had persistent well water problems. The water smelled of sulfur. The pressure was inconsistent. Fixtures were staining orange. She called multiple plumbing companies and received conflicting advice — one said she needed a new well pump, another said she needed a water softener, a third said the problem was in her pipes. She spent money on repairs that didn't last and equipment that didn't address the actual cause.
The Decision She Made
After that experience, Priscilla made a decision: she would build the kind of plumbing company she wished had existed when she needed help. A company that tested the water before recommending treatment. A company that diagnosed the system before pulling the pump. A company that told customers the truth, even when the truth was that they didn't need the most expensive option.
What She Built
Deep Dive Plumbing Maryland was founded on that principle. Every decision Priscilla makes — from who she hires, to how jobs are priced, to how customers are communicated with — comes back to one question: would I want this done in my own home? That question has guided the company from its first job to its most recent one.
The Standard She Holds
Priscilla holds the team to a standard that most plumbing companies don't bother with: test before you treat, diagnose before you replace, explain before you charge. It takes more time. It requires more expertise. And it's the reason Deep Dive has a 5.0 Google rating built entirely on real results — not marketing.
About Priscilla Foster
Priscilla Foster is the founder, owner, and operator of Deep Dive Plumbing Maryland — a licensed, woman-owned plumbing company based in Dunkirk, Maryland. She built this company not because plumbing was her lifelong dream, but because she experienced firsthand how difficult it is to find a plumber you can actually trust in Southern Maryland — and decided to do something about it.
Priscilla oversees all daily operations at Deep Dive Plumbing Maryland, including customer scheduling, job coordination, quality control, estimating, vendor relationships, licensing compliance, and company growth. She is the first point of contact for many customers and takes personal pride in making sure every homeowner feels heard, informed, and confident before any work begins. Her standard is simple: treat every customer the way she would want to be treated in her own home.
Under her leadership, Deep Dive Plumbing Maryland has earned a 5.0 Google rating built entirely on honest work and real results. The company has grown from a small local operation into one of the most trusted plumbing teams in Calvert County and Southern Anne Arundel County — serving communities from Dunkirk and Owings to Chesapeake Beach, Prince Frederick, Annapolis, and beyond.
Priscilla works alongside her husband Terry Foster Jr. (Maryland Master Plumber #98433) and father-in-law Terry Foster Sr. (Journeyman Plumber, 40+ years experience). The family business structure means that the values — honesty, hard work, accountability — are the company values. There's no gap between what the company says and what it does, because the people who own it are the people doing the work.
Priscilla is a Southern Maryland native who understands the unique challenges homeowners in this area face — older homes, private well systems, iron-heavy water, acidic groundwater, and limited access to truly qualified plumbers. She built Deep Dive to solve exactly those problems, and she shows up every day to make sure the company lives up to that promise.
As a woman who built a licensed plumbing company in a male-dominated industry, Priscilla is passionate about supporting other women in the trades and in small business. She believes that diverse ownership makes the industry better for everyone — especially customers — and she takes pride in running a company where every customer is treated with equal respect, regardless of who they are.
Priscilla holds the team to a standard that most plumbing companies don't bother with: test before you treat, diagnose before you replace, explain before you charge. It takes more time and requires more expertise. It's also the reason Deep Dive's reputation in Southern Maryland is built on word of mouth — neighbor recommending Deep Dive to neighbor, one honest job at a time.

What Priscilla Oversees
Customer Experience
Priscilla is often the first voice a customer hears when they call Deep Dive. She takes personal pride in making sure every homeowner feels heard, informed, and confident before any work begins. Her standard: treat every customer the way she would want to be treated in her own home.
Quality Control & Standards
Priscilla sets and enforces the Deep Dive standard for how jobs are diagnosed, how repairs are performed, and how the team presents itself in customers' homes. Every job is reviewed against that standard before it's considered complete.
Scheduling & Coordination
She coordinates the team's daily schedule to ensure fast response times, on-time arrivals, and efficient job sequencing. When a customer has an emergency, Priscilla is the one making sure the right crew gets there as fast as possible.

Priscilla oversees all daily business operations — estimating, invoicing, vendor relationships, licensing compliance, insurance, and company administration. She runs a tight ship so the technical team can focus entirely on the work.
Company Growth & Strategy

Community & Local Roots
Priscilla didn't build Deep Dive to be a regional franchise. She built it to be the best plumbing company in the community she calls home.
What Customers Say
"Priscilla was so easy to work with — she kept us updated every step of the way. The crew showed up on time, protected our floors, and the work was flawless. This is exactly the kind of company Southern Maryland needs."
"I called three plumbers before Deep Dive. Priscilla was the only one who asked me to describe the problem in detail before quoting me. She scheduled the right crew for the job and they fixed it right the first time. I've recommended them to everyone I know."
"As a woman homeowner, I've had plumbers talk down to me or try to oversell me. Priscilla runs a completely different kind of company. She explained everything clearly, the price was fair, and the work was excellent. I trust Deep Dive completely."
