About Chessy Whalen

Chessy joined OC&C directly from university and has built her career with the firm over the past nine years. She specialises in the B2B sector, with a particular focus on the end-to-end lifecycle of buildings and infrastructure. Much of her recent work has centred on supporting clients critical to enabling the energy transition across Europe and the US, combining important environmental outcomes with major commercial opportunities.

Alongside her client work, Chessy has been a strong advocate for inclusivity at OC&C. She has played a leading role in the firm’s LGBTQ+ network, which has risen to 14th in the Stonewall Workplace Equality Index, making OC&C the top-ranked consulting firm in the list. Chessy is focused on building strong, collaborative teams and helping the next generation of consultants develop their careers.

She comments:

“I am passionate about investing in the talented people we hire at OC&C and helping them become the best consultants that they can. Growing and developing our team is the only way we can keep raising the bar on the work we deliver for clients.”

 

About Asher Cohen

Asher began his corporate career industry-side before moving into consulting to tackle the most strategic challenges facing businesses. At OC&C, he has developed significant expertise within the Consumer Goods sector, working with both global multinationals and high-growth challengers.

He is particularly proud of building long-term client relationships, supporting businesses across multiple stages of growth; from strategy and M&A through to operating model and go-to-market design. Asher believes OC&C’s strength lies in its ability to advise clients across the full company lifecycle, even within an increasingly uncertain world.

He comments:

“At OC&C, I genuinely think we are uniquely placed to help our clients given the full lifecycle of companies we work with – we have the privilege of knowing the challenges global giants are trying to solve as well as the ones on the road ahead for rapidly scaling businesses which creates a virtuous circle.”

 

Strengthening OC&C’s Global Partnership

Chessy and Asher’s promotions strengthen OC&C’s global Partner team and reinforce the firm’s expertise in Consumer Goods, B2B infrastructure and Energy Transition. Their appointments underline OC&C’s commitment to supporting clients as they navigate a rapidly changing world, and to nurturing the next generation of consulting leadership within the firm.
