Elizabeth Nowinski, DVM 

Dr. Lisa, as she prefers, earned her undergraduate degree in biology from Wayne State University.  In 1990 she graduated from Michigan State University College of Veterinary Medicine.  Dr. Lisa is a firm believer in continuing education and feels it is important to properly educated owners regarding pet health and disease prevention.  She takes pride in practicing quality medicine tailored to specific needs of each pet and their family.

Dr. Lisa decided to become a veterinarian at a young age.  Looking back she recalls a story that greatly influenced that decision.  "During my preschool years," she began, "I would help my mother garden.  At some point, I brought a very dead, dehydrated worm to my father asking him to help me save it.  He helped me 'rehydrate' the poor creature by packing it in dampened tissues overnight.  The following day, I checked my first patient and discovered a fat, sassy earthworm in the box - I can still remember the thrill of a successful treatment regimen and I was hooked!"  It wasn't until years later that she discovered the truth; her father replaced the dead worm with a vibrant healthy worm.  "This memory still makes me chuckle" she tells us.

Dr. Lisa was born and raised in Michigan.  She and her husband have four children and share their lives with "Abby", a loving Labrador Retriever.  Her hobbies include preparing educational materials for school Science Olympiad competition, gardening, camping, and always looking to learn something new.     


John Gumbs, DVM

  Dr. John Gumbs founded Global Veterinary Services.  He graduated from Tuskegee University School of Veterinary Medicine in 1982, interned at Tuskegee the following year, and completed residency at Michigan State University School of Veterinary Medicine in 1986.

Dr. Gumbs then joined Professional Veterinary Hospitals (PVH), which was the largest group of small animal practices in the state of Michigan.  There, he helped set up the first surgical referral service outside of the university setting within the 13 plus small animal clinics owned and operated by PVH.  

The venture was a success as more than 100 clinics referred patients to this referral service.  Business boomed, and many clients wrote thank-you letters to him for the kind manners expressed towards them and their pets.

Even after experiencing the tremendous growth and success at PVH, Dr. Gumbs decided to join Michigan Veterinary Specialists in Southfield.

There he was staff surgeon and performed countless cruciate ligament repairs, disc surgeries, and fracture repairs.  He has also performed many gall bladder removals, open heart surgeries to remove heartworms in cats, and gastric dilation volvulus procedures.  Other surgeries that he commonly performed include elective orthopedic procedures such as OCD, FCPs, UAP, angular limb deformity, luxation repairs and total hip replacement.

In 1997 Dr. Gumbs chose to start his own business, Global Veterinary Services, and he travels all over the southeast portion of Michigan!  He continues to operate 20 plus cruciate ligament repairs weekly, fracture cases, total hips, TPLO, and has added the TTA (Tibia Tubercle Advancement) procedure to his list of surgical services.

Dr. Gumbs lives in a suburb of Ann Arbor with his wife, three Leonberger's, and three horses.
