Our Team


Denny Holoran [Customer Service Manager]

All our customers LOVE dealing with Denny (pictured left). As our Customer Service Manager she embodies the bright, friendly spirit of OM and is always on hand to give support and advice and generally make sure that our customers receive the best care in the industry.

If you've ever felt like you're not being taken seriously enough when on the phone to a lens supplier, you'll understand why a fantastic attitude like Denny's makes such a difference. 







Elle Holleley [Operations Supervisor]

Elle Holleley

Elle (pictured right) joined OPTIK MIZEN from a retail background in June 2017 and has taken to optics like a duck to water! Bright, bubbly and full of energy she has proved a fab addition to the OM Team and loves the variety of dealing with the many aspects of our lens distribution process.

Elle works alongside Denny and is always on hand to help you with a query or take down an order. 









Rob HarnettRob Harnett [Founding Partner]

Director/Partner Rob Harnett is extremely passionate about the independent sector and is dedicated to helping independent practices thrive. As well as promoting the OM brand, Rob is very much involved in the development process of our multi-focal designs (particularly with assessing user experience in our patient trials), and is always on hand to provide technical support and advice.

Rob is generous with his time and very happy to travel to meet with you to explain our lenses and provide training to your dispensing team. And as our customers will attest, you won't meet a nicer, more genuine guy than Rob in the industry. [Follow Rob on Twitter @TheLensGuy] 




Jamie Holoran (with Holly!)Jamie Holoran [Founder & CEO]

Our CEO (pictured right with OM mascot "Holly") has 25 years experience in the industry and is highly regarded for his conscientious and ethical approach to business, as well as his supportive leadership style.

He was one of the first people in the UK to embrace the benefits of progressive lens digital surfacing and he made the technology available to independent practices a full three years before Essilor.

Jamie works tirelessly to ensure OPTIK MIZEN has access to - and can incorporate into its production - the very latest advances and most innovative technologies. He is continually driving the company forward to ensure that the quality and performance of the OPTIK MIZEN portfolio remains on par with that of Essilor, Nikon and Zeiss. Partnering with the best independent minds in global optics, Jamie was closely involved in refining and perfecting the highly sophisticated design mappings of our EQUINOX 2.0 and LIFE SYNCHRONICITY progressive lenses.




Justyn WalcottJustyn Walcott [Relations Director]

As an independent family business OPTIK MIZEN shares a natural synergy with the independent practice, and no one appreciates that more than Justyn (pictured right).

Justyn likes to stay in constant contact with our customers to ensure that everyone remains delighted with the lenses and service they receive from OPTIK MIZEN. His super-friendly manner and focus on integrity in business perfectly encapsulates the OM ethos -  so it's little wonder that Jamie and Rob were delighted when Justyn agreed to join the Board of OM in November 2017. 






Sav Nicotra [Financial Director]

Sav is a chartered accountant specialising in innovative and dynamic SMEs and has played a key advising role in the development of OPTIK MIZEN since its inception.

It's in part thanks to Sav that OM is able to operate so efficiently, bringing elite digital lenses to the UK independent market at a fantastic price point.


Stephan Heilig [Lab Manager]

Stephan is in overall charge of lens production in the lab. He has almost a decade's experience in top-tier lens manufacturing and sets his standards extremely high. He insists on incredible cleanliness and has the lab staff spend almost as much time cleaning our equipment as making lenses! He has developed a very specific process for applying the various stages in the EXCELCIS AR coating process which results in greater adhesion between the layers. Though very serious about his vocation, Stephan also has a keen sense of humour that makes for a very positive and friendly working dynamic in the lab.


Marie Leitner (QC Supervisor]

Marie is Supervisor for Quality Control in our lab, with an eagle eye that ensures not even the tiniest blemish is allowed to escape the production line. 




What we all have in common at OPTIK MIZEN can be summed up in one word: passion.

We LIVE AND BREATHE both lenses and relationships.

We love what we do. We believe in what we do.

Let's work together.
