Dr. Siegel & Dr. Leas

Dr. Leas & Dr. Siegel have been practicing their profession for years.

They are dedicated to providing the most comprehensive dental care possible for their patients.

Dear Patients, Colleagues and Friends,

It is with the greatest reluctance that I write to you today to share the news that I have decided to retire from Dentistry at 1818 Market Street. I am leaving Dentistry at 1818 Market Street in the hands of Dr. Jonathan Siegel; my friend and partner of close to 20 years.

As many of you know, I started this practice over 50 years ago in a different location on Chestnut Street. Over five decades, I have tried to build an environment and a level of care that match my personal and professional standards. I consider it a testament to those standards that I’ve had so many of you alongside me for so many of those years. I love my work and I’m proud of the care we’ve been able to provide for so many. Above all, I’m proud of the friends that have come to feel like an extended family, both of my staff and among my patients and peers.

This was a difficult decision to come by and was not made lightly, The realities brought on by the COVID-19 pandemic have created many unexpected changes. One particularly painful reality is not being able to say my goodbyes in person. What will remain the same is the standard of care provided by Dr. Siegel, the commitment to your safety, and the amazing staff that will continue to treat you with skill and kindness.

It has been my privilege to be part of your lives, to help provide beautiful and healthy smiles across 51 years of personalized care, and to have shared so many laughs, conversations, moments and milestones with you all. I truly hope I have served you well.

Warmly,
Maurry R Leas, DDS
