For many years now, Karen has taught me proper oral hygiene. Her expertise lies not only in her skill and knowledge, but in her ability, patience and tact in dealing with a patient who still has a lot to learn. I have never known a better oral hygienist. Dr. Val is very fortunate to have her on her staff. I have never known a dentist (Dr. Val) who has had a friendlier, more helpful and courteous staff. I love them all.
