I feel incredibly fortunate to have been under the care of Dr. Lisa Guerra for the last 2+ years. From the very beginning of my journey, she demonstrated not only remarkable surgical expertise but also the kind of genuine compassion and professionalism that are increasingly rare in medicine today.Dr. Guerra took the time to explain every aspect of my diagnosis and treatment options with clarity and empathy. She listened carefully to my concerns, answered all of my questions with patience, and made sure I felt comfortable and informed at every step. Her calm and confident demeanor gave me peace of mind during what could have been an overwhelming time.The surgery itself went flawlessly, and I credit Dr. Guerra’s precision, attention to detail, and experience for my smooth recovery and excellent outcome. But what stood out just as much as her technical skill was her deep kindness and humanity. I never once felt like “just another patient” — I felt seen, supported, and truly cared for.Dr. Guerra is not only an outstanding surgeon but also a compassionate healer who brings heart into everything she does. I’m endlessly grateful for her care and would recommend her to anyone in need of a surgeon who leads with both excellence and empathy.

Great DoctorI was very fortunate to have been referred to Dr. Lisa Guerra by Dr. John Link who has cared for me the last 20 years. As soon as I met her, I knew why Dr. Link had chosen her for me. Dr. Lisa Guerra is a very compassionate physician who is also extremely knowledgeable. She put me at ease right away and I never felt rushed. The fact that she spent an hour and a half with my husband and me proves how thorough she was. Dr. Guerra is also very responsive to her patients; she answered my email right away!
