    Dr. Lannon provided me with the best care I have ever received, despite a sad outcome. The nurses that cared for me (I think Shauna, Lori and Marissa) were kind, careful, compassionate and knowledgeable. I'll always be grateful for the care I received here.

    Really appreciated the timeliness and thoroughness of the provider I saw. She contacted my cardiologist for recommendations and called me before the day was over. I would recommend this clinic to all of my pregnant friends!
