"My daughter who is intellectually disabled is a difficult patient to treat. Dr Ross is the best. I truly appreciate his kindness and patience with my daughter. I have 100% confidence in his abilities."



"We had a great experience. I especially appreciated the hygienist, who was very open to our more holistic approach to dental/healthcare. We've been working with Dr. Ross for 5 years and have been pleased."



"The entire LPDA office staff was very friendly and accommodating. Dr. Ross was so very patient with my son, who has pretty significant dental anxiety. I couldn't have been more pleased with how well my son did or how knowledgeable Dr. Ross was with all my questions. Extremely happy to have found our new dental home! 😀"



"My son had his second dental appointment but first with Lancaster Pediatric Dental Associates today and it was such a positive way to start our day. The staff was welcoming, the waiting room very clean, and the toys for the kids were amazing. My son is a year and a half and usually does not enjoy the doctor or the dentist but he actually had a great time playing and interacting with Dr. Ross. We felt much more at ease here than we did at another dental office we tried at first. I highly recommend for small children!"



"We had a great experience with out 16 month old seeing Dr. Ross. The office was inviting and clean, the staff was friendly and Dr. Ross was enthusiastic and informative. So happy to have LPDA for our son's dental care and he was enamored with Molar Mike!"
