Jeffrey L. Lenow, 54, of Medford, a family physician and lawyer, died of a heart attack Monday at home.

Since August, Dr. Lenow had been chief medical officer for the Vox Medica Institute for Continuing Healthcare Education in Philadelphia. He had previously held the same position with Cardinal Health in Philadelphia, a provider of health-care and pharmaceutical products.

Dr. Lenow was also an associate professor at Thomas Jefferson University, where he was on the staff of the department of family and community medicine. "He was there at least one day a week," said his wife, Roseanne Bourgeois Lenow. "It was important to him to keep in contact with patients."

Dr. Lenow was founding president of the Pharmacy and Therapeutics Society; a member of the credentials committee for Independence Blue Cross of Philadelphia; and a member of the Beneficiary Advisory Panel, which advocates for prescription benefits for military families.

He graduated from Lower Merion High School, where he was on the swim team. He earned a bachelor's degree from Temple University, a medical degree from Hahnemann Medical College, and a law degree from Temple. He never intended to practice law, his wife said, but wanted to learn how legal systems pertained to medicine. He was especially intrigued about maternal-fetal rights, and published a paper on the subject.

He and his wife met at the St. Agnes Medical Center, where she was a lab technician and he was doing a rotation while in medical school. They married in 1982. For five years they lived in the Midwest, where Dr. Lenow taught at the University of Illinois and was on HMO staffs in Illinois and Wisconsin.

When they returned to New Jersey in 1992, Dr. Lenow completed a residency in family medicine at Virtua Memorial Hospital Burlington County in Mount Holly. His medical education had been interrupted by law school, his wife said.

Dr. Lenow was president of the Medford Chase Homeowners Association and coached softball and baseball for the Medford Youth Athletic Association. He made videos for the athletic association and made a video of the Jefferson family-medicine staff for its recent Christmas party. He loved playing show tunes on the piano, his wife said.

He often contributed letters on a variety of subjects to Philadelphia newspapers.

His constant companions, his wife said, were his  two labradoodles Callie and Emma.

In addition to his wife, Dr. Lenow is survived by a son, Matthew; daughters Stephanie and Sarah; his parents, Mae and Martin; and a brother.

A funeral will be held at 4 p.m. tomorrow at Fellowship Alliance Chapel, 199 Church Rd., Medford, where friends may call after 2:30 p.m.
