Mark O'Sullivan's biography

At a glance

  • Wrote and directed the award-winning My Sexual Abuse: The Sitcom
  • Wrote and starred in Channel 4's Lee and Dean, and the creator of ITV's Tell Me Everything
  • Host of the podcast Making Lemonade

Mark O’Sullivan is a writer, director, and actor best known for his work in television. He co-created, directed, and starred in the Channel 4 comedy Lee and Dean, which aired for two seasons.


His first drama series, Tell Me Everything, produced for ITV and the BFI's Young Audiences Content Fund, addresses mental health and the challenges faced by young people today.


In 2024, Mark presented his first documentary for Channel 4 titled My Sexual Abuse: The Sitcom, which was awarded the prestigious Royal Television Society 2025 Programme Award for Art. The documentary followed Mark on his journey to explore the abuse he suffered as a child, and his attempts to make a live studio sitcom about his experiences. It received rave reviews in the UK press and media. Charities working with survivors of sexual abuse have even reported an increase in people accessing their services following the programme’s first broadcast.


Most recently, Mark launched Making Lemonade, a platform that includes a podcast, talks, workshops, and live events. Drawing from the "lemons" that Mark has experienced in his life, this initiative aims to demonstrate how creativity can transform difficult experiences into positive outcomes, effectively turning lemons into lemonade.


Before starting his career in television, Mark spent almost two decades working as a facilitator, teacher, and trainer—firstly in education, then for organisations in the public, third, and private sectors. He has designed and delivered talks, seminars, and workshops on topics from issues-based programmes like domestic abuse and hate crimes, to harnessing creativity and resilience. Mark now offers a range of talks and workshops that can be delivered 'off the shelf' or tailored to suit your organisation's specific requirements.

Does PepTalk charge a booking fee?

No. PepTalk adds no booking fee, so you pay the speaker's fee and nothing beyond it. The service, from shortlist through to contracts and event-day logistics, is included. For repeat or multi-event bookings, PepTalk can agree preferential rates with your procurement team.

What happens after I send a brief?

Share your event date, audience, format, objectives and budget, and PepTalk sends a hand-picked shortlist within 24 hours. Each suggestion comes with a profile, a fee and a recommendation on the strongest fit. Once you choose, PepTalk handles contracts, travel and logistics through to event day.

What does the typical fee range mean?

The typical fee range is the speaker's standard in-person fee in their home market, shown in their local currency. It moves with format, location, date and session length: virtual sessions and shorter slots usually cost less, while international travel and peak dates cost more. Send your brief to PepTalk and the team will confirm the exact fee in your currency.

Have all the speakers on the website worked with PepTalk before?

Not all of them, and it makes no difference to your booking. PepTalk's network of 15,000+ speakers covers talent the team works with directly alongside speakers represented by agents and agencies worldwide. PepTalk approaches the speaker, negotiates the fee and handles contracting either way.

How far in advance should I book a speaker?

Three to six months ahead is comfortable for most events, and 12 months is better for large conferences, peak-season dates or one specific in-demand speaker. Shorter timelines are workable, and PepTalk regularly fills last-minute and replacement bookings within days. Availability is the constraint, so get in touch as soon as you have a date.
