Johnston Carmichael, a UK-based independent accountancy and business advisory business, has bolstered its leadership team with four new appointments.

Tamsyn Weston joined the company as chief technology officer in Edinburgh. She will lead the company strategy across IT, cybersecurity, digital development, AI and automation.

Weston has more than 20 years of experience in technology, transformation and cybersecurity roles in regulated environments. Her role will focus in part on the responsible use of emerging technology to support the company's growth.

In Glasgow, Deborah Ramsay has joined as an audit partner.

Ramsay is a chartered accountant and has held Responsible Individual status since 2020. She brings more than 20 years of audit experience, including a background at a 'Big Four' company.

Katie Lange has also joined Johnston Carmichael as a director in Aberdeen, while Leani Passano has been appointed as director in the Audit Quality, Risk & Technical team.

Lange has nearly 20 years of global payroll experience, having worked across the oil and gas, financial services and technology sectors. Her work has focused on process improvement and client service.

Passano has worked at international and UK accountancy practices, with experience in sustainability reporting and assurance.

Johnston Carmichael CEO Lynne Walker said: "Tamsyn, Deborah, Katie and Leani bring deep experience and new perspectives to Johnston Carmichael.

"Their appointments strengthen the technology behind our business, the audit expertise we offer clients and the specialist support available across our UK offices.

"They demonstrate the calibre of people we continue to attract, and I look forward to seeing the contribution they make."

Last month, Johnston Carmichael appointed Sam Nicholson as the head of its dental team.
