Here’s What People Are Saying

Dr. Johnston has been my doctor for 6 years and delivered all 4 of my boys.  His staff treats you like family.  I highly recommend him.

Krystle S.OB Patient

Dr Johnston delivered my last 2 boys. I wish he would have delivered my older 3 children cause he’s the absolute best ever. Now he’s mine and my kids’ Dr and I refuse to see anyone else. I just love him to pieces and love how he takes the time to listen to my concerns and addresses them. I recommend him whenever the chance arises. Your the best Dr J.

Courtney Lynn S.OB Patient

Dr. Johnston was our family doctor for five years. He is the perfect combination of brilliant and kind! Eight years and two states later his genuine thoughtfulness is still echoed through our home. He delivered two of our children and helped save my life. I think the world of him and consider myself fortunate to have been his patient in those challenging times.
