I just want to say that the Unionville Post Office is amazing! I mail a lot of packages so I’m there every day and I’m always treated so kindly. There is one particular employee and I’m sorry I don’t know her name but she is outright the nicest woman I have ever met! She has so much patience too! I have 4 children and this is the first time I ever received anything like this but in my mail yesterday were two letters from Santa addressed to my girls! Not only did this make their day but it truly touched my heart! Unionville Post Office Absolutely Rocks!
