My husband recently passed away at age 92. He always claimed that the good care of him given by Dr. Tynan was responsible for his longevity. I do agree. The Doctor was there whenever we needed him and gave us a lot of personal attention towards the end of my husbands' life. For that, I am most grateful.
Thank you for taking the TIME in making me feel at home on our first visit! you and your very kind and sweet staff did just that! And thanks for updating one medicine of mine that needed it! You all give of yourselves and that is a wonderful trait to have in our fast-paced world!!
