Head Receptionist


Here, at Market Street Dental Practice, I love the positive energy felt by everyone and I really appreciate the attentive care our dental clinicians and team strive to provide, as individuals and collectively, to each patient.

My favourite part of my job is meeting new people every day and I love that each day I learn something new. As Head Receptionist I look forward to helping you sift through the ins and outs of your dental journey, as well as assisting you in achieving a smile that is out of this world.

Being with Market Street Dental Practice for a couple of years,  I have come to appreciate how positive the environment is and how we all work extremely well together to provide the best service for you. 

I moved to the UK from Italy in 2014, I love experimenting with different cuisines in the kitchen and doing all things outdoorsy with my family. If you catch me in a moment alone you might find me sewing, crafting or repurposing an old treasure into something new!

Tina Sharma

Practice Manager


I started my dental career in 2013. I have 9 years of administration experience in the dental industry, out of which I had the opportunity to serve patients as a dental nurse for 4 year, as well as over 17 years in customer service. 

My goal is to incorporate the wealth of knowledge and customer service that I have acquired to equip our team to best serve our patients and their families.

I love and enjoy my job as it means working alongside various specialists and the opportunity to interact with wonderful people on a daily basis.

Apart from my dental career, I am trained in Classical Indian Dance ‘Bharatanatyam’  and am a Certified International Performing Arts Artist. In my personal time I train, choreograph dance projects and engage in community services and festivals. Apart from dance, I am a devout Cricket Lover and enjoy exploring and experimenting with international cuisines.
