Meet the Open Doors team

Our dedicated, professional team have many years of experience in the property letting and management industry. We pride ourselves in our high standard of service.

David Gilson

Lettings Director

In 2007 I was studying a RICS degree at Oxford Brookes University specialising in sustainable development and became a College and County tenant. I have always had a real interest in properties and in particular, property investment. Right from the start I could see what a great culture and ethos Mark had created with College and County and in late 2007, I started my journey with C&C and became a viewing agent working part time around my studies.
Some 10+ years on I am now Lettings Director for both College and County and Open Doors. My goal every day is to ensure that whilst we stay at the cutting edge of the market with new technologies and grow as an agency and team the same care and personal approach that Mark gave when I started is always taken with every Landlord and Tenant to ensure what makes Open Doors great always remains.

Jalina Jessome

Lettings and Property Management Administrator

Coming from the East Coast of Canada, I am new to the Country of England and the Open Doors team.
Eager to learn the business, I have joined as Property Management and Lettings Administrator.
I am looking forward to getting to know our Tenants and Landlords, the lovely character homes that we manage, and familiarising myself with Buckingham and its surrounding areas.
I am passionate about creating memorable customer experiences and dedicated to ensuring all parties feel that their home is in good hands.
In my free time I enjoy travel and cooking. England has always been on my bucket list, and I am so thrilled to be here and experience the way of living.

Lizzie Brand

Lettings Negotiator

I have been in the property industry for nearly three years specialising in both lettings and property management. I have recently joined the team here at Open Doors and am excited to work alongside Nicola matching tenants to our properties and securing lets for our landlords.
In my spare time I enjoy cycling and will be embarking on a 300 mile ride to Paris this July!

Mark Crampton Smith


Tea boy and occasional odd job person… Trouble shooter and property sleuth. Taking ownership of Open Doors, an agency that shares the same ethos as our other agency College and County in Oxford, is an exciting challenge. I share my time between both Oxford and Buckingham and I am confident that the staff team can both maintain and improve the services to clients and tenants alike. Through our adherence to ethical letting, we hope to attract more excellent landlords who with strong advice, will continue to invest in their portfolio.
I enjoy game fishing and working my dog and I am also developing my understanding of the local market trends and shifts. If you would like to share your perspective on any of these, perhaps we could meet up for refreshment? Call me on 07775522532

Nicky Tchertoff

Property Manager

I have been working in the property industry now for 12 years and throughout my journey I have learnt so much along the way. I have always enjoyed the property management side building up relationships with tenants and landlords and ensuring the properties are well looked after. I really enjoy seeing all the properties and in Buckinghamshire we have some great villages with lovely character properties.
I have recently moved to Milton Keynes which I am still working my way around as there are a lot of roundabouts. I am looking forward to working at Open Doors with a fresh team to ensure all your property needs are met. In my spare time I enjoy glamping in my VW camper van called Jingles and seeing all the sights along the way.

Alice Fox

Viewing Agent

I have recently joined the Open Doors team and I am excited to be part of such a wonderful and reputable company.
I will strive to keep our clients and customers happy, and I am looking forward to helping tenants find their ideal home.
In my own time I am quite creative and enjoy arts and crafts. I have an amazing young daughter who is a real character and keeps me on my toes! I grew up on a local dairy farm and I love the outdoors and exploring in the countryside.

Penny Berrington

HR/ Office Management

Born and raised in South Africa I decided to broaden my horizons and moved to the UK in 2008, I have now settled in Oxfordshire and have two beautiful little girls. I have been working with Mark since 2010 at College and County (Letting Agency in Oxford) where I started off as a Lettings Negotiator and gained knowledge and experience of the industry, I have since changed roles where I now do the HR and the office management for both Open Doors and College and County.
