Angel Croce, Staff Manager at Colorado Skin & Vein in Denver

Angel Croce

Staff Manager

Angel has been in healthcare for more than 20 years. Her journey began in 2004, after her father suddenly passed away from a stroke. Losing him was a life-changing experience, and it inspired her to choose a career where she could help others and give patients and their families the care, compassion, and support they need during difficult times.

Throughout her career she has worked across cardiology, neurology, family practice, and urgent care — each experience helping her grow both personally and professionally. She now works in vascular care and aesthetics, where she enjoys building relationships with her patients, helping them understand their care, and making sure they feel comfortable and supported throughout their journey.

Outside of work, Angel is a proud mom of two. Family is incredibly important to her, and in her spare time she loves being outdoors with her husband and their two dogs — hunting, fishing, and enjoying Colorado.

For Angel, healthcare is more than a career — it is personal. What started as a way to honor her father’s memory has become more than two decades of caring for others, and she is grateful to keep doing something that means so much to her every day.
