5 Stars  I absolutely adore Dr. Thrash! His expertise in skin care and medicine is so refreshing. Before I scheduled my first appointment, I was so unhappy with my skin, I lacked confidence and needed a change. Dr. Thrash listened to my story, gave a few looks and knew what to prescribe me immediately. His staff is great! He is very timely, thorough and always suggest’s the best products. –
