Meet the Tiger HR Team



Tiger HR VANESSA-CHALLESS3-200x300 WHO WE ARE   Tiger HR was founded by Vanessa Challess whose strong background in commercial litigation gives her a unique perspective on keeping clients away from disputes and hourly charges.

When she realised how many of her legal clients’ expensive legal requirements arose from a lack of sound HR & Employment Law advice and support, she became determined to do something for the many companies, furiously busy developing their businesses, who had  neither the time nor expertise to have proper HR practices in place and for whom, the larger HR consultancies are a poor fit.

As a natural-born entrepreneur she truly understands the real world challenges of running a successful business. Her clients appreciate her clarity, willingness to really listen to their concerns and the context of their issues and her weather eye and timely advice on what pitfalls might lie ahead for them.

Vanessa lives in Kent with her husband Alex and three children. She enjoys travelling, good wine and making things happen.

Leonie Savory

Legal Consultant


Tiger HR LEONIE-SAVORY2-450x450px WHO WE ARE   Leonie is a key part of the legal support that underpins Tiger HR’s services. She recently completed 5 years part time study to attain a 2:1 in her LLB with Open University – a course she has combined with raising 2 kids, now aged 5 and 8 years. She is now a Trainee Solicitor with Tiger Law.

She is currently studying for her LLM and LPC at the University of Law in Bloomsbury. Her 5 year stint as an advisor at Citizens Advice Bureau means Leonie has exactly the sort of real world experience that makes her ideal for Tiger HR’s down-to-earth philosophy. Leonie has a particular interest in private client work and helps business clients arrange their personal planning to work hand in hand with their business succession strategy.

With school-age kids, a demanding part time University course and her increasingly busy role with both the Tiger companies, we were sensitive when asking Leonie if she had any other interests! Her getaway is the Health & Fitness Centre and she likes to run.


Tiger HR REBEKAH-MANNING-72B WHO WE ARE

Rebekah Manning

PA to Vanessa Challess



Rebekah deals with all our day-to-day running and client support and is key to the smooth running of both Tiger Law and InHouse Legals. Vanessa has been known to refer to her as her “office wife”.

Bex is often the first person that clients encounter and they soon come to know her as the reliable and persistent lynchpin of tiger Group operations, relentlessly chasing down paperwork from authorities like the Courts and Land Registry – a particularly thankless task given recent budget cuts. She keeps Vanessa and the team’s workload and billing on track and manages the various systems and case management tools that we rely on to run the business.

Bex loves music, especially the live and loud variety, reading and movies. She has a small and adorable daughter and, as of December 2017, a baby son as well. She and her husband are expert roadtrippers. If you have ever dreamt of trekking across the US in an RV, ask Bex on a quiet day - if she ever has one.

Tiger HR SARAH-BROWN450x450px WHO WE ARE

Sarah Brown

Administrative Assistant




Sarah joined the Tiger Group to help with our rapidly increasing workload in early 2018, not long after we moved to our new offices in Wye. Her original career was hairdressing but her long term sights have always been on a legal career.

Currently, Sarah is in the process of studying to gain her Legal Secretarial qualification and hopes to progress to become a solicitor eventually. Her duties at Tiger HR are allowing her to gain valuable experience and insight into Employment Law issues.

Sarah has three kids at home, two girls and a boy, the eldest is coming up to 9 years old., So unsurprisingly she is on the on the move morning, noon and night. She enjoys socialising when she can and loves music and keeping fit at the gym. 

She really loves hot weather and is never happier than when the sun is doing some serious shining so she and family escape the damp Kent countryside whenever possible to head for sunnier climes.
