Dr. Burrell Heyward Jr. Has retired and his practice now operates under new owner Dr. Albert A. Coombs IIIDMD, a young professional endodontics specialty dentist and who also works with fellow dentist Dr. Grainger with a second office in Temple Hills, MD. I had a referral for a retreat for an old root canal and I was fortunate enough to get an appointment the next day with Dr. Coombs III. The practice is clean, the front desk staff is professional and extremely knowledgeable. Dr. Coombs is professional, explains your treatment plan in detail, cares that his patient is comfortable, and does a fantastic job. I will have to update this as they will need to change the name here on Unilocal from Dr. Burrell to Dr. Coombs III as he deserves to have his own Unilocal listing.
