Callum has been recruiting finance professionals since 2014, specialising in the placement of accounting professionals from AAT Trainee through to senior finance level. He works with both SMEs and large corporations, tailoring his approach to meet the needs of each client and candidate.

Believing in quality over quantity, Callum takes a consultative approach and delivers results with a 3:2 CV-to-interview ratio, ensuring clients aren’t bombarded with irrelevant CVs. If he can work exclusively, he knows he’ll deliver the best outcome. And if you prefer a recruiter who picks up the phone over endless emails, you’re in the right place.

In a candidate-driven market, Callum uses his accountancy recruitment expertise to attract and approach the best talent.

“In terms of job satisfaction, for me, there is almost no better feeling than finding that ‘gem’ for one of my clients – I say ‘almost’ because offering someone their dream job happens to be pretty high on the list too!”

“We had an excellent experience working with Callum at Harvey John when looking to hire a Finance Manager and Credit Controller. From the very beginning, they were incredibly personable, responsive, and dedicated to understanding our specific needs. Callum took the time to learn about our company culture and the key attributes we were looking for, ensuring that every candidate he presented was a great fit. Throughout the process, the communication was clear and timely, making what can often be a challenging hiring process seamless and efficient. Their professionalism, industry expertise, and commitment to finding the right person made a big difference. Thanks to Callum’s hard work, we found two fantastic additions to our team”

CFO, Tax Consultancy

“We have been partnered with Harvey John for a number of years now and we have consistently found their expertise, their approach and their professionalism to be at the highest quality. They take the time to know our business with on-site visits and virtual calls, in order to find the right fit for our needs and culture. Callum has been a pleasure to work with during this time and is a prime example of Harvey John’s work and culture. We continue to have a great relationship with Harvey John and look to maintain this for years to come.”

Talent Acquisition Specialist, Health Care

“I have trusted Harvey John for their expertise and reliable services for nearly 11 years. My journey with them began in 2014 when David Waddell placed me in my first finance role in the UK…Since then, I have had the pleasure of working with Georgina Hayes, who introduced me to an excellent candidate when I was recruiting a Finance Assistant for my team. Her understanding of my requirements was instrumental in finding the right fit.

In more recent years, I have come to rely heavily on the impeccable work of Callum McKenna. Callum is always the first recruiter I think of whenever I am looking to expand my team. He placed an outstanding Management Accountant with my team at previous company and, more recently, supported the recruitment of a Senior Management Accountant for current my team.

Callum has an exceptional ability to understand the exact profile I am seeking. He asks insightful questions and gathers all the necessary information to provide a highly curated shortlist of strong candidates. His thoughtfulness, professionalism, and impeccable communication make the recruitment process seamless and supported every step of the way.”

Finance Director, Manufacturing

“Working with Georgina and Callum has been a fantastic experience. They take the time to truly understand our business, our culture, and our specific recruitment needs, ensuring they match us with the right candidates. Their personalised approach and attention to detail have made the process seamless and efficient. Over the past six months, we’ve successfully recruited a permanent Assistant Management Accountant and a temporary AP Clerk—both of whom have been excellent additions to our team, bringing valuable skills and fitting in seamlessly. We highly appreciate their support and look forward to continuing our partnership.”

CFO, Telecoms

“I’d like to express my gratitude to Harvey John but specifically to Callum for his patience, understanding and support during a busy recruitment period. High quality candidates were always put forward and Callum has always listened to, adhered and most importantly pre-empted our needs as a business. His expertise in the field of finance aided us in finding our perfect candidates. Thanks Callum”

HR Advisor, Transport

The fastest, easiest, and most effective recruitment process I’ve ever experienced.

Dr. Alistair Livesey, Managing Director

Africa Power Limited

“Callum supported us in a recruitment campaign for a number of finance posts. Having tried previously without success to fill these roles ourselves, Callum identified new sources of potential candidates which has resulted in some excellent appointments. He fully understood our requirements and kept in regular contact as the campaign progressed. This was all despite the added challenges of the lockdown.”

Interim Head of Finance

Reigate & Banstead Borough Council

“Callum has been absolutely fantastic! At the beginning of January 2022 I was in the process of looking for a new role and had mixed results before speaking with Callum. I immediately noticed his personal approach and support throughout the entire recruitment process and within a week he was able to secure me a first interview with a company, followed by a second interview and then I was offered the role which I duly accepted. I cannot thank Callum enough, and would highly recommend him to anyone.”
