Coach & Performance Analyst

Signal Tennis

Your obsession deserves a coach to match.

Tennis coach. Performance analyst. Former solicitor. I qualified and practised as a lawyer, completed a Master's in Data Analytics at UCD with First Class Honours, and walked away from both careers because I couldn't stop thinking about tennis.

What started as a hobby during Covid became an obsession, then a career. I trained as a coach, earned my Level 1 and Level 2 ITF coaching licences, and built Signal Tennis to combine the two things I care most about: coaching and data.

Unlike my career as a lawyer, my analytics background isn't a footnote. It's central to how I coach. Sessions are supplemented with video breakdowns, point-by-point statistics, and structured development reports. Feedback is precise, objective, measurable and actionable: not based on feel alone.

I don't step onto the court without a lesson plan tailored to the player's goals, learning style, and recent developments. A lesson isn't done until I've updated my notes on what worked, what didn't, and what to focus on next time. Players/parents get regular updates on progress and development areas, not just when something goes wrong. I set out development blocks with clear objectives and measurable outcomes, and I track progress against those outcomes over time.

Whether working with juniors pushing toward national rankings or adults sharpening their competitive edge, the approach stays the same: understand the data, identify the patterns, and build a plan that drives measurable improvement.

The Signal

Every system I've built for my clients (the video analysis pipeline, the performance reports, the stat tracking, the match-prep frameworks) started as something I built to improve my own game.

For Juniors & Parents

On top of my work with kids looking to pick up tennis or improve, I've spent:

  • 291 hours (as of March 2025) on-court with our high-performance academy players
  • Hundreds of hours reviewing their matches
  • Countless more preparing analysis on over a decade of junior tournaments, matches, rankings, and development outcomes
What does this mean? I know the most common technical and tactical errors, checkpoints, and proven development approaches for players at every junior level. I've studied how many matches is too many at what age, whether playing at too-difficult or too-easy a level is linked to performance outcomes, and what junior factors are most predictive of long-term success.
For Adults

I know what it's like to be stuck. I know what it takes to break through. I picked up this sport as an adult and competed at a level I thought was beyond me. You can too. All you need is the right information and the discipline to act on it.

Why I Coach, and Why I Believe Anyone Can Improve

This isn't a highlight reel. My playing credentials are modest to say the least. However, I strongly believe that my journey in tennis so far is proof that deliberate practice, honest self-assessment, and structured improvement work at any age. You just have to separate the signal from the noise.

The Short Version

I grew up competing in football, basketball, Gaelic football, and ultimate frisbee, captaining Ireland underage in ultimate and playing two sports at university level for UCD. An ACL tear in 2015 ended all sport for six years. When I picked up a tennis racket during Covid in 2021, I'd never had a private (or group!) lesson and hadn't been a club member since age 10.

Within six months I'd won my first club championship. Within three years I'd climbed from the bottom division to the top of the national rankings in the intermediate divisions, built my own analytics systems, and decided to make coaching my career. Every tool I've built for my clients started as something I built for myself.

BEFORE TENNIS

A Competitive Sporting Background

Five sports growing up. Four competitively. Sport was everything.

Football: County league and cup winner at multiple underage levels; undefeated league winners in senior year Basketball: Team captain, leading scorer, player-coach Ultimate Frisbee: Captained Ireland underage; captained school team to Leinster final Gaelic Football: Minor B champions Tennis: Recreational with my brother and schools teams

At UCD, I played ultimate frisbee and basketball at university level. Lost in the national freshman intervarsities final. In 2015, I tore my ACL in a football match, ending all sport until 2021. During that time I qualified as a solicitor and completed my MSc in Data Analytics.

2021

The Year It Started

April 2021. Started playing tennis during Covid on study leave. I can't say I started with much of a 'base'. Never had a lesson. Hadn't been a club member since age 10. 4-4 junior singles record, with the high point being a u14 0-6 1-6 2nd round loss in the local open. Three months of paid leave. Played every day. Became completely obsessed.

  • By June: social competitions
  • By July: first open tournaments: 3-2 record in Class 7, losing in the 2nd and 3rd rounds
  • By August: made a Class 7 final
  • September: won the singles club championship (Div. C) at my home club
  • October: moved to Dublin, joined a new club, won their Div. C singles championship
2 Club Championships (Div. C) Finished 6th nationally: Div. 7
2022

Climbing While Working Full-Time

Less time to play. Still improving. Won the B division club championship in singles after moving up from C the year before. Moved from Class 7 to Class 5 in opens. The jump was real.

  • Club championship B singles winner, B doubles finalist
  • 1-2 record in two Class 5 opens
Club Champ: B Singles Finished 132nd nationally: Div. 5
2023

The Plateau

Struggled at the same level.

  • Best open finish: a quarter-final loss in Class 5.
  • Went 4-4 in the club championships. All 2nd round exits
Finished 137th nationally: Div. 5

Two straight years stuck in the 130s nationally. Something had to change.

2024

The Breakthrough

Took time off after years of juggling law, my masters, and full-time work. Initially, I thought I would take a few months off to recover from burnout and pivot from my legal career (which I always knew I wanted to leave) into a role as a data analyst/software engineer. I had spent over a year working with the technology group in my firm and I was excited to finally put my masters to good use.

Dove headfirst into tennis. Never came back out. This was the year I started building systems (physical, technical, tactical, and mental), many of which later became tools for my clients.

I tracked every match. Logged what worked and what didn't. Recorded opponent tendencies. Built mnemonics for staying relaxed on court. Created custom match-prep guides. Bought a ball machine and designed training programmes for myself. Started analysing tennis statistics obsessively (both amateur and professional) and became consumed with building systems to track real progress.

  • May: won singles and doubles titles at home club open (Class 5): 8-1 overall. Stopped playing Class 5 from that point.
  • May/June: Moderate success in five straight Class 4 opens (6-4, one semi-final)
  • July: County Dublin Class 4 singles final: lost in 3rd set tiebreak (5-1 in the draw to reach the final)
  • September: Club Championships: 13-1 record. Won B singles, B doubles, and Div. A mixed doubles. Lost Div. A singles semi-final - three years after starting in Div. C.
  • By the end of the club championships, I had played 198 matches for the year. I finished the tournament with a Grade 3 hamstring tear - the cost of averaging 5 matches a week for nine months.
3 Club Championships (B Singles, B Doubles, A Mixed) Class 5 Open: Singles and Doubles County Dublin Class 4 Final Finished 1st in Div. 5 (of 215) and 14th in Div. 4 (of 456)
2024: THE PIVOT

From Player to Coach

Decided tennis was how I wanted to spend all my time. Sidelined with my hamstring injury, I invested in long-term development instead of taking a new job. Started training as a coach that autumn, with the long-term view of combining coaching with my analytics background.

I began shadowing Mark Finegan with our regional performance squad. Mark was a Division 1 NCAA coach and former Irish national champion. I studied tennis coaching methodology, attended workshops on disability tennis and coaching skills, took copious notes on the leading experts, and started volunteering as a coach with vision-impaired tennis. I continue to coach vision-impaired players to this day, and it's been one of the most rewarding coaching experiences I've had so far.

I started building what would become a database of over 500 drills and formalised the mental, tactical, and technical systems I'd developed for my own game into structured coaching frameworks.

At the end of 2024, I received my Level 1 qualification and had a decision to make:

  1. Stop ignoring the recruiter emails and go back to the higher-paying, more stable world of corporate law.
  2. Look for a job in data analytics or software engineering while I explore coaching on the side.
  3. Go all in. Invest in coaching full-time and take the time to build the right foundations for a long-term coaching career.

After years in a career I knew wasn't right for me and working on things I had zero passion for, I chose to follow my passion, and I've never looked back.

Coaching, competing, and building

Started working as a private coach with Naas LTC and joined our performance academy as an assistant coach in January. I started my Level 2 coaching course that spring, taking up many of my evenings and weekends for the next few months. By September, I'd taken on the role of performance analyst for the academy - recording, tagging and analysing over 50 matches and providing development analysis on roughly 20 players.

In addition to my role as assistant coach/performance analyst with the academy, I coach many of the students privately as a support coach.

Less time for my own game. Moved up to Division 3 opens (and the occasional Division 2). The transition closer to the top levels was difficult: 9-7 in singles. Focused more on doubles: won 3 open titles in Class 2/3, lost a Division 1 final, and defended our A mixed doubles club championship title. Lost in the A doubles final as well.

2025: CLIENT RESULTS

Private coaching outcomes

I keep a small roster of private clients. In 2025 I focused on group coaching while gaining experience, building out my systems and completing more coaching qualifications. I have recently opened up capacity for some additional private clients in 2026. For transparency: the only long-term clients omitted below are players too young to compete, adults who don't compete, or academy players who I don't want to take credit for their results.

Signal Tennis Launches

Took over as lead coach of our weekend performance academy group. Developed and launched Signal Tennis and the Signal Portal. Carried out in-depth research into long-term player development pathways, club performance metrics, and benchmarks for success at different levels of the game.

Started work as the league coach for Clane LTC's doubles campaign. Five teams across the men's and ladies' draws.

  • Men's 1st team stayed in Class 3: avoided relegation for the first time in 6 years
  • Ladies' 1st team finished 9th of 48, losing in the playoff quarter-final
  • Overall win rate of teams I worked with increased year-on-year from 30% to 39% across 81 matches

Our Approach

Great coaching isn't guesswork. It's a structured process of observation, analysis, and intentional practice.

Observe

Every match and practice session is a source of data. Video and live observation capture what the naked eye misses.

Analyse

Raw footage becomes structured insight: patterns in errors, strengths under pressure, tactical tendencies.

Target

Prioritise the changes with the highest return. Not everything at once. Focused, deliberate improvement.

Review

Track whether changes are sticking. Repeat the cycle with each session, building a clear development arc.
