"Dr. Sampson and staff are a model of how a practice should be run. Dr. Sampson takes a deep, personal interest in each of his patients, and is very kind, empathetic, and very knowledgeable."

"Every one there was very nice and caring. Dr. Venanzi is an amazing doctor! His nurse, Gloria, told me I could call anytime with any questions or problems."

"Your staff was BY FAR the nicest group of medical staffing I have ever come in contact with! I've also never met a doctor that I like as much as Dr. Gleick. He was nothing short of fantastic. I highly, highly recommend him as well as this practice."

MJ Marretta-Lewis  did an excellent job answering all of my questions & explaining them in a way that I could easily understand. She was professional and thorough and made me feel at ease from the moment she came through the door. I was extremely pleased with my care and would recommend her to family and friends without hesitation."

In describing his approach to care, Dr. Gleick emphasizes compassion and careful attention to each patient, noting "Listening to patients is very important, and so is communicating clearly. I like to keep things down to earth — humor helps, too. All of these characteristics help build a sense of trust and confidence."

Dr. Gleick received his medical degree from the University of Kentucky College of Medicine, and completed his residency at Bethesda Hospital Family Practice. He is also a Diplomate of the American Board of Family Practice. Notably, Dr. Gleick was awarded the honor of 'Kentucky Colonel' by Kentucky Governor Paul Patton, in recognition of his volunteer care for underserved patient populations.

Board certified in family medicine for over 25 years, Dr. Sampson emphasizes a 'whole person' approach to care, considering all aspects of a patient's well-being. "Taking the time with each person to fully understand his or her unique needs is vital. Guiding each patient along a path toward a healthier life that's more enjoyable and fulfilling — even if it's just one step they can incorporate — is my goal during every visit."

Dr. Sampson is an honors graduate of Ball State University, and received his medical degree at the Indiana University School of Medicine. He is also an active member of the American Academy of Family Physicians and the Ohio State Medical Association.

His approach to patient care reflects this experience; he sees trust and mutual understanding as being key to the best possible care. “In working with each patient, knowledge is so important — it is vital that the patient is fully educated about his or her condition and the treatment choices available, and that I completely understand every aspect of their health and lifestyle goals before recommending a course of action. From that foundation, we can build a true partnership in better health and well-being.”

Prior to private practice, Dr. Venanzi served with distinction in the United States Air Force, receiving numerous citations as a Flight Surgeon, with over 300 hours of combat flight time, and as a top-level physician and administrator, including service as Chief of the Medical Staff of the 88th Medical Group at Wright-Patterson Air Force Base.
