“Cathy was so kind and compassionate. I came in to see her for worsening symptoms after no relief from ER visit. Her compassion made all the difference. I could tell she really wanted to help me. And she did. I was so happy with my visit with Cathy- she’s an amazing provider.”

Amazing. Nurse was kind, warm and helpful. Doctor was the same. So knowledgeable and took my concerns seriously and made me feel like she cared about my health (many doctors treat you like a number). Talked about follow up and what her next steps would be. I walked out feeling confident in this practice and definitely making her my primary care provider. Highly recommend.
