About
A finance partner for owners who want to understand their own numbers.
Glendalough Advisory is a fractional CFO firm based in New Jersey. We work with owner-led businesses across industries that want clear, steady insight into their finances without building a full-time finance team.
How we work
A monthly rhythm, prepared in advance, explained in plain language.
We meet with you on a regular monthly cadence to review cash flow, key reports, and upcoming decisions. Before each meeting, we prepare clear, simple reports so you can see what is happening in your business at a glance. During the call, we walk through the numbers in everyday language and talk through your options for staffing, spending, pricing, and growth.
Between meetings, you have a finance partner you can call when a lender asks for a package, a large customer changes terms, or an opportunity needs a quick model before you say yes.
What we believe
Four commitments behind every engagement.
Plain language
If a report needs a translator, it is not finished. We write and speak so an owner can act on it.
Steady rhythm
Good financial management is a habit, not a rescue. We show up on schedule, every month.
Owner's perspective
We weigh decisions the way an owner does: cash, risk, people, and the life you want the business to support.
Confidentiality
Your books are your business. Our data handling is documented and held to a written standard.
The name
Why Glendalough.
Glendalough is a glacial valley in County Wicklow, Ireland, known for two still lakes and a monastic settlement that has stood for over a thousand years. It is a place of clear water and steady ground.
That is what we try to bring to a growing business: a clear view of what is really there, and solid footing for the decisions ahead. The landscapes across this site are a quiet reminder of that idea.
Leadership
Founded by Joseph Purtill.
Joseph founded Glendalough Advisory to give owner-operators the kind of financial partnership that larger companies take for granted: someone who prepares the numbers, understands the business behind them, and is available when a decision cannot wait for the next quarterly meeting.
The firm is a New Jersey limited liability company serving clients across New Jersey, New York and Pennsylvania.
