“I rated my experience based off my call…”
Visited on January 5, 2025
I rated my experience based off my call but what I was not pleased with was getting this consultation set up. I was called and told that I would be connected with someone in the next 10 minutes; only to have then been told that I would need to reschedule for the next day. I am glad I did speak with Marisa who was not the original person I was set up with but, this isn’t the 1st time I’ve been rescheduled. Both occasions happen because of something on Defy’s end creating an inconvenience for me.

Dr Calkins was great. He answered my questions, discussed in detail my lab results. Defined my plan for the next 6 months. Time ran out before I could think of another question.

“I liked Marissa and thought she was…”
Visited on January 4, 2025
I liked Marissa and thought she was thorough. I particularly liked that she looked at some of my blood work that was out of balance and said, let’s do another blood test to see if we can get to the bottom of why this is always off. That gave me confidence that she was curious and looking under more rocks than other care I have had.,
