Our Physicians
Frank Kucer M.D.
Dr. Kucer was born and raised in the Pittsburgh area. He graduated from college with a degree in Chemical Engineering.  After graduation, he realized his love for people rather than that of machines and processes. He moved to Philadelphia to attend Jefferson Medical School where he met his wife, Kathy. They had four sons who are now all grown with children of their own. They have now started and love their new "career" as Grandparents. Dr. Kucer takes pride in a “patient based” practice philosophy.  All of his decisions are based on what is best for you, the patient. He will take the time to listen to your concerns and appreciates your trust in the practice.

Ronald Markos M.D.
Dr. Markos was trained at Hahnemann University Hospital and has been part of the practice since 1992. Every year he learns more about himself and his calling as a physician. Dr. Markos has a goal to always improve himself for the sake of his patients who rely on him. He strives to apply these skills with compassion and understanding with the hope that his patients will experience these priorities. Dr. Markos met his wife when they were teenagers in his church’s youth group. They went to college in Central New Jersey and eventually in Philadelphia. They have two children and he draws his strength and the balance for his life from his family.

Kathleen Lukaszewski D.O.
As the newest member to the practice, Dr. Lukaszewski brings excitement and high energy. She has had a lifelong ambition to take care of patients and medicine is a second career.  Dr. Lukaszewski started in physical therapy and worked for several years in adult rehabilitation. Dr. Lukaszewski went to medical school at The University of Medicine and Dentistry of New Jersey and completed her training in internal medicine and Gastroenterology at Temple University Hospital. It has been Dr. Lukaszewski’s privilege to serve the Upper Bucks Community for the past three years. Dr. Lukaszewski considers herself to be an East Coast girl.  She was born in New Jersey and educated in Boston, New York City and Stratford. When she is not in the office or Endoscopy Center,  you can find her on the beaches of Cape May County or on the ski slopes in the Pocono’s. Dr. Lukaszewski is proud to provide comprehensive and compassionate care to her patients and would like to thank you for placing your trust in the practice to satisfy your GI needs.

About Us

The Center for GI Health, formerly known as Upper Bucks Medical Associates, has been serving the community since 1973. Our practice has expanded over the years from one to four physicians. CGI is dedicated to provide the highest level of care combining experience and education with compassion and understanding. We have most recently added a female physician to our practice in 2006. This has added a level of comfort for those patients who seek a female to deliver their GI care. CGI has full staff privileges at Grand View Hospital located just across the street from our office and Endoscopy Center.
