Dr. Gillen is a wealth of knowledge and truly cares about her patients. Thanks to her guidance and wisdom, I’m well on my way to reaching my health goals. Unlike many doctors, she actually takes the time to listen and offers thoughtful, realistic solution without any pressure. I feel genuinely supported and empowered in my health journey with her.

had this to say:
I recently had a SkinWave facial at Mosaic and I absolutely loved it! Dr. Alexia was very gentle and knowledgable-explaining the different products and techniques she used and why they were important. I left feeling refreshed and clean, without any redness or puffiness like other facials leave you! I highly recommend Mosaic Medicine!

had this to say:
Dr. Gillen and her team provide amazing service. They are so knowledgeable and truly listen and care about clients needs and concerns. I’ve had hydrofacials and microneedling with excellent results. I definitely recommend the red light therapy after the microneedljng. My skin looked and felt great with no downtime!

had this to say:
I couldn’t be more happy with my experience with Dr. Gillen, I finally feel like I have a partner in someone who actually cares about the whole picture of my health! She approaches an overview from multiple angles including nutrition and gut health, hormone levels and stress, and lifestyle and emotional stability. I love that she has a PhD background to deeply understand the complexity and science, as well as the functional approach. If you’re looking for someone to “piece it altogether” and talk to you like a friend, she’s your person!
