Dr. Peter Crossey


I’ve only been with the practice for 3 years but I’m really happy with the care I get from the dentist and the team. More importantly, I’m totally happy with the care and attention my kids get. I’ve been impressed with the care given on more than one occasion and I trust the team to give me the right advice on the best treatment. Stephen is our family dentist and while I wouldn’t say I look forward to an appointment, I’m pretty confident and comfortable with it all. I’d definitely recommend the team at Mount Oriel to family and friends. Sarah
Having only recently joined this practice I have been made to feel welcome and confident in relation to the standard of care and treatment.  Stephen has been extremely thorough in his approach and has taken the time to explain my treatment options.  This has enabled me to make informed choices, something that is of utmost importance to me.  Stephen has completed my dental treatment expertly and with care and consideration throughout.  Every step of my treatment has been delivered with utmost skill and professionalism. I have been delighted by everything he has done for me and would have no hesitation in recommending him and this practice to friends or family should the opportunity arise.   Patient A
I’ve been with the practice for more than 10 years and I’m really happy with my smile. My sister recommended Mount Oriel and I’m glad I made the move. I get regular notifications to attend for check-ups and I think because of that I’m pretty much free of any dental problems. It’s all down to the great care and attention Mount Oriel provide. Regular check-ups, the latest dental technology and x-rays all prevent future damage. Mount Oriel strive for preventative care.  I’ve been lucky that I haven’t had major work done – but if I did, I would know that I could take the procedure in my stride. Mark is great – very likeable and he puts you completely at ease and Jennifer at Reception really goes out of her way to make each visit easier and more enjoyable. Anna
