Dr. DAVID J. MONTGOMERY

ANN COGILL
Appointment Coordinator
“Chester County Family Dentistry is my ‘home away from home’. I love working with a team who is so very dedicated to the well-being and health of our patients. I’ve learned from Dr. Dave and Dr. Ryan (and Dr. Don before them), and all the hygienists, how important maintaining good dental hygiene helps our entire body. We have the greatest patients and my job is keeping in touch with them and helping them schedule their checkups. Working here for a little over 30 years has afforded me the pleasure of seeing our patients grow from children to adults to parents, and for some, grandparents! Having 4 children and 11 grandchildren myself, I have grown with them and appreciate this circle of life and feel truly blessed!”
Ann is also in charge of our continuing care call system. You will get a call or email from her if it is time for you to schedule your next cleaning and exam visit.
WENDY BIRONT
RDH – Dental Hygienist
“As one of our dental hygienists, I am proud to say our hygiene department takes the latest technology and current research combined with caring personal service creating what we hope is your best dental experience ever.”
I’m a graduate of Thomas Jefferson University (B.S. in dental hygiene) and have completed Masters courses in Public Health at West Chester University. Of the plethora of continuing education I’ve attended, my interests lean toward diabetes management, disease prevention, sterilization, and practice management. This year commemorates a 30 year dental hygiene career and I can honestly say I would choose this career path all over again if given the choice today. When I’m not in the office I'm working my side hustle Dental Fillins, a staffing agency I co-own with Danielle RDH. The best part of my day is spending time with husband Mike and our 2 sons; Rustin HS senior Michael and freshman Bradley supporting them at lacrosse tournaments and boy scout events. And yes, I do still remind them to brush and floss their teeth everyday!”
DANIELLE SYDENSTRICKER
RDH – Dental Hygienist
“I am a graduate of The University of Pittsburgh’s Dental Hygiene program in 2004. Periodontal therapy is my passion. I love coaching patients on elevating their home care to achieve a healthier oral biome. My other passion is owning and operating a dental staffing agency Dental Fillins. I live in southern Chester County with my husband Brett and our two amazing children Trey and Genevieve.”
ERIN P.
RDH – Dental Hygienist
“Dental Hygiene is a stimulating career with new advancements and technology. Each patient is diverse and unique requiring different treatment needs and education that varies from appointment to appointment. That is what makes each day new and exciting.”
SHELLEY BROWN
Financial Coordinator
“I began working in the dental field 20 years ago and truly enjoy what I do. I am one of your first points of contact at Chester County Family Dentistry; here to assist and guide you through the first steps of achieving the smile you have always dreamed of. I strive for meaningful and thorough patient relationships, ensuring every patient is comfortable and fully-informed about their treatment options.”
Outside of the office, I love spending time with my wonderful children, traveling and I always make time for a peaceful walk. My two youngest boys are teenagers and have a love for high school football and of course, PS5 (LOL). When they feel like spending time with mom Khalil, Joseph Jr., and Camwren are a joy to be with.
CORINNE MAGUIRE

“I moved to Chester County over 20 years ago and have been amazed at the rapid growth. I hope all new residents will come to trust our dental practice for all their family’s needs. We all are committed to staying informed on the latest dental education and technology.”
BECKY SHOTWELL
CDA, EFDA – Certified Dental Assistant, Expanded Function Dental Assistant
“I have been working here with the office for over 20 years now, and still loving every minute of it. Throughout the years here I have strived to be the best at what I do. I am one of our Expanded Function Dental Assistants (EFDA). This means that you will see me with a more “hands-on” role while you are in our dental chair as I help the doctors to improve your smile. Behind the scenes, I manage our Social Media pages and to try and keep up with the times! I look forward to putting beautiful smiles on patients' faces because they put a smile on mine every day. I look forward to meeting you and welcoming you to our Dental Family.”
TEONNA HARRIS

“It makes me so happy to see patients walk out of our office with a smile on their face!”
I’ve been working for Chester County Family Dentistry for almost three years now and I love it here! It’s welcoming atmosphere makes me feel blessed that I was given a chance to be a part of such a great team. I graduated from Contemporary Health Career Institute in 2018, where Becky (our EFDA), and Sunny (one of our hygienists) were my teachers. I enjoy helping others, assisting chair side, and getting to know each and everyone!
SUNNY RAHMAN
RDH - Dental Hygienist
“I am a new addition to this wonderful practice. I graduated from Penn College with my Bachelors in Dental Hygiene in 2012. When I’m not being a dental geek, I love traveling around the globe exploring, tasting food and experiencing different cultures. I always find a way to make everything adventurous. I try to live by the saying "life is better when you are smiling" and I strive to give my patients the same motivations.”
Kit Foster
Appointment Coordinator
"I have been at CCFD for 1.5 years now. This is the second dental office that I have worked for after spending 30+ years as an Administrative Assistant in academia. This new 'career' has taken me to new areas of patient care that I have never experienced before. I now have the pleasure of directly helping patients and am able to see the outcomes first hand. Knowing that I have even a small part in a patient's care gives me immense satisfaction."
Shannon Montgomery
