Patty McKenna, RDA / Office Manager

l’m Patty McKenna and have had the pleasure of working in our dental office for over 25 years as an RDA and Office Manager. l’ve been very fortunate to have worked with my great co-works for most of these years and to have the nicest patients in all of Petaluma.

My husband Dan and I moved to Petaluma 30 years ago and have raised our son and daughter here and have enjoyed all Petaluma has had to offer our family. 2016 will be a very exciting year for us our daughter and her husband are expecting our first grandchild in January and our son is getting married next July so we are looking forward to the next journey of our growing family life.

I enjoy spending time with our family, cooking, walking, hiking trails out at the coast and all around beautiful Lake Tahoe. I also enjoy traveling and have visited many beautiful and fascinating places but the highlight was for our 25th wedding anniversary we did a trek in the Himalayan’s in the Annapurna Region to Machhapuchhre base camp. Look forward to seeing you in our dental office or just around Petaluma!
