"The supporting personnel are all very efficient and professional. They go out of their way to make you comfortable. Dr. Thyssen is awesome. He is so positive and explains the test results very clearly. Even though it is years between tests, he never forgets you. He, too, is so professional."

"I’ve been a patient of Dr. Wienstock for many years. This medical practice has greatly improved and extended my life. One additional facet I’ve always been impressed by is the non-medical yet healing nature of the landscaping they have been intentional in creating and maintaining. As with the advanced medical practice, likewise the greenscaping. Bravo."

"I had an endoscopy/colonoscopy. Dr. Singh and her staff were professional and courteous, with a great bedside manner to boot! The procedure went smoothly, and I was provided with an in depth report of all of their findings. I highly recommend her!"

"I have been a patient of Dr. Thyssen for over 30 years. The professionalism on display in his practice is eclipsed only by Dr. Thyssen himself. I cannot imagine being able to find a more compassionate, dedicated person of medicine anywhere. He seems as much a friend as a doctor."
