Catherine Gannon


Founder and managing partner

I spend my time working out what clients actually need rather than what solicitors think they want. From there, I focus on how to deliver the best service at the best price – this involves my on-going search for talent and frequent review of costs.

Work and clients

I am passionate about enterprise and those prepared to risk all and set up a business. With a tax and accountancy as well as legal background, I offer the rare ability to put commerciality into practice. I oversee matters spanning all of the practice areas drawing on many years of experience to provide direction.  I am not as grand as to have forgotten that Gannons was a start up once upon a time.

I am a regular writer and speaker for a variety of commercial organisations.

Recent experience

  • Acting for the seller of a franchise business involving 25 outlets, to a quoted company buyer. Key to the deal was ensuring that the franchise model was not adversely affected
  • Preparing a share option valuation for the purposes of a CSOP scheme for a major tour operating company
  • Assisting in seven rounds of unapproved option grants to key employees of a successful finance company.  The trade meant that the business could not qualify for any of the HMRC approved option arrangements
  • Preparing a post-completion investment agreement for the management team following the completion of their MBO of an enforcement agency. The agreement permitted the management team to subscribe for further shares at a “sweat equity” value providing the target met certain financial projections
  • Using an unfair prejudice petition as leverage to negotiate a departure for our client, a minority shareholder in a mobile application development company, with uplift in the market value of our client’s shares due to a lucrative contract obtained pre-completion.
  • Advising a senior employee of a robotics company on the implication of becoming an employee shareholder where the employer intended to gift the shares. This involved strategic tax advice and advice on share rights
  • Acting for a former director and shareholder who was dismissed by his employer and lost his entrepreneurs’ relief. Our successful challenge of the dismissal led to a commercial settlement agreement and damages equal to the loss of tax.


After qualifying in the accountancy profession as a Chartered Tax Advisor (CTA), I qualified as a solicitor and gained experience at international law firms before establishing Gannons in 2002.

Why I love my job

I give back to the economy via job creation, training and taxes. It feels good to know I am actively contributing to Brand GB.  I have learnt a lot along the way and have been very privileged in working with some industry greats.  I pass their knowledge shared with me onto my team who pass it onto our clients – another great feeling.  What is there not to like?
