The 12 cardiologists who left The Heart Center at Northeast Georgia Medical Center earlier this year have opened a new practice in Atlanta and will soon have locations in Braselton and Lawrenceville.

The Northside Cardiovascular Institute physicians who were formerly employed with the Northeast Georgia Health System are:

  • Dr. Allison Dupont

  • Dr. Brenda Hott

  • Dr. Christopher Leach

  • Dr. Mark Leimbach

  • Dr. Jeffrey Marshall

  • Dr. Mark Matthews

  • Dr. Kashyap Patel

  • Dr. Mehrdad Toosi

  • Dr. Pradyumna Tummala

  • Dr. Steven Wang

  • Dr. Heather Westmoreland

  • Dr. Andrew Yen

“As we discussed how to best continue our pursuit of excellence in comprehensive cardiovascular care, we knew we needed a partner like Northside Hospital that shared this vision and had the energy to go to the next level,” Marshall, chief of Northside Cardiovascular Institute, said in a statement. “We are excited to begin this new partnership.”

Northside Cardiovascular Institute is located at 1110 West Peachtree St. in midtown Atlanta. New physicians will soon join the group, which will have offices in Atlanta, Braselton and Lawrenceville.

Northside spokeswoman Katherine Watson said details about the new locations would be provided when available.

The cardiologists suddenly left NGHS in June, opting to not renew their contracts. The Heart Center has 14 locations in the region, including in Gainesville, Braselton and Buford.
