Dr. Mareth was great. He asked me if I was having any issues. Listen to what I said and talk to me about what he was going to do to help me with my issues. Talked about my last visit and explain to me why he wanted to get some more blood work. He spent all the time I needed to understand what was going on, and I couldn’t recommend

I was so pleased he was referred to me. He explained everything to me regarding my bloodwork and I was able to ask him questions about my bloodwork without feeling rushed. He is one of the best doctors I have ever had.
