Dr. Ashley Koester, DVM

I am blessed to have spent a lot of time at my father’s veterinary hospital while growing up in small-town Indiana. When I was four years old, I remember watching him perform surgery on Tuesdays so that my mom could run errands. On Christmas morning, my three siblings and I would always walk the dogs that were staying at the hospital before opening our gifts. We were only allowed to enjoy the Christmas festivities after the hospital chores were finished. Growing up with my dad’s practice next door was a wonderful experience that gave me an understanding of what it takes to be a terrific veterinarian.

I attended college at Northwestern University where one of the highlights was playing varsity lacrosse. I was a captain of the 2005 team that went undefeated and won the NCAA Division I National Championship. After Northwestern University, I received my veterinary degree with distinction/honors from Purdue University.

The Manhattan and Hermosa Beach communities are perfect for my lifestyle. My identical twin sister, Courtney, and I recently hiked the 220 mile John Muir Trail from Yosemite Valley to Mount Whitney, and I have fallen in love with surfing. You may also spot me running on the strand or playing tennis at Live Oak Park. Sprout, my two year old Goldendoodle, and I enjoy paddleboarding and hiking together, too. I recently started volunteering with CASA of LA, a non-profit that improves the lives of foster children.

Getting to know my patients and their owners is my favorite part of being a veterinarian. I am constantly in awe of the complexity and strength of the bond between pets and their human parents and I am honored to play role in keeping pets and owners together for as long as possible. Although I love to celebrate happy and healthy pets, I also find reward in providing knowledge and support in those difficult times. My goal is to improve the quality of life for all involved and I am grateful that I get to do this daily!

Dr. Natalie Poulter, DVM

Growing up as an only child I accumulated many pets that became my “siblings”. Having the mentality that our pets are family ultimately led me to want to care for them in every way possible so becoming a veterinarian was only natural. A southern California native, I obtained my undergraduate degree at Loyola Marymount University. During college I worked as a veterinary technician and learned the ins and outs of the profession from highly skilled and experienced veterinarians in the area.

After a trip to Costa Rica and Panama providing veterinary care to large and small animals, my love for travel was ignited. When the opportunity to obtain my Doctor of Veterinary Medicine degree on the Caribbean island of St. Kitts was presented, I took it without a second thought. The Ross University veterinary medicine curriculum was demanding and living in a different country proved challenging though scuba diving and relaxing on the white sand beaches definitely made things bearable. I continued expanding horizons, working with veterinarians in South Africa on rhino conservation, lions, various antelope species, and many others at the world-renowned Kruger National Park. Finally, I completed my clinical year of education at the Auburn University School of Veterinary Medicine in Alabama and externships at the top veterinary facilities around the nation as well as practicing advanced spay/neuter techniques.

Following veterinary school, I completed a rigorous rotating internship at the Animal Specialty and Emergency Center (ASEC) in Los Angeles working with specialists in surgery, internal medicine, radiology, and cardiology, as well as many hours in the emergency and critical care department.

My personal interests include pain management, endocrine disorders, and mixing alternative therapies for a multi-pronged approaches to any disorder. In 2017, I will be certified in acupuncture and the practice of Traditional Chinese Veterinary Medicine. When I’m not in the clinic, I enjoy yoga, cycling, and spending time with my Golden Retriever, Charlie, and two cats, Ramsay and Minni.

Dr. Andrew Krieger, DVM

As far back as I can recall, I have wanted to be a veterinarian. This was even my answer to 'what would you do if you didn't have to work'. My passion for veterinary medicine is what gets me racing into work every morning, I have the best job in the world! This passion started somewhere around preschool. I was fortunate enough to have local veterinarians take me under their wings and help develop my skills to take on this challenging, fulfilling career. I remained focused through grade school, undergrad (not as easy as it sounds) and earned my D.V.M. from The Ohio State University in 2008. I served an externship at Rood & Riddle Equine Hospital in Lexington, Kentucky and worked and trained in every department at MedVet Specialty and Emergency Hospital in Columbus, Ohio.

My first position as a veterinarian was with a mentor who was an accomplished surgeon. I rapidly developed a strong interest and began doing my own advanced procedures including orthopedic surgery. Since moving to South Bay in 2009, I have been able to enhance my skills in dentistry under the mentorship of Dr. David Nielsen. His passion to provide exceptional dental care has been passed on and I am proud to offer most of the services currently available at AMG including root canals, crown restoration, vital pulpotomy, disarming, and more. When I'm not practicing medicine, I enjoy spending time with my two children, Emery and Gavin, and my wife Aimee (also a veterinarian). When time allows, I enjoy running, skiing, biking, and great wine with friends.
