Meet Joan

I celebrated my 25th year of practicing hygiene with Dr. Clements on July 31st, 2012.
Many times I look at my posessions and say a quiet thank you for having a great boss that has allowed me to achieve these goals.

Living less than 10 minutes from work is wonderful and I get to see so many of my patients out of the office. It is great to catch up between their recare appointments.

My husband, Mike, is a P&G employee and we will celebrate our 29th year of marriage in November. My daughter, Miranda, graduated from Wilkes Summa Cum Laude with a BA in English.

Also sharing my home are six dogs. A Westie, a Collie, 2 English Cockers and 2 Italian Water Dog.
Since I have such a passion for dogs, it has caused me to become a certified dog groomer for which I practice one day a week.

Mary and I refer to our schedules as our guest list and that is how we hope all our patients feel when they come to our office.
