Dear Friends,
After 20 years of serving you (15 years as solo) in Bucks and Montgomery Counties, I am closing my practice as of  January 31, 2015.  It has been a fantastic journey, which finally has come to an end.  Being your personal physician has been very gratifying, both personally and professionally over the years.  I would like to thank you for all your support and kind words.
The phone line will be active for next 3-4 months.  If you wish your medical records mailed to you,  please call the number and leave a detailed message.  The CD containing the digital files will be mailed to you promptly.  
Take care and God bless.
