David Carlson, MD

Medical Director

Born in Minnesota, raised in Dallas, Dr. Carlson graduated from high school just down the road at Richardson High. He was an undergraduate at UT Austin and attended UT Medical School of Houston. His family practice residency was at St. Paul Medical Center, Dallas, Texas. He has conducted his solo practice since 1988. As a fixture in the Dallas medical community for more than 25 years, it was originally during his last year of residency in Family Practice that he began working at what was then called the St. Paul Medical Center. Just a few years later he bought the clinic. And the rest, as they say, is history. Dr. Carlson has always worked hard to provide the right choice for Family Care, Urgent Care, and Emergency Care in Garland and in 2009, he renamed it Bestcare Family Medical Center.

phys-recog-diabetesdavid carlson mdIn 2013 and again in 2016, Dr. Carlson received the NCQA (National Committee for Quality Assurance) Diabetes Recognition Program. NCQA developed the Diabetes Recognition Program (DRP) to provide clinicians with tools to support the delivery and recognition of consistent high quality care. D Best 2017This voluntary program is designed to recognize clinicians who use evidence-based measures and provide excellent care to their patients with diabetes. Those who achieve DRP Recognition show their peers, patients and others in the medical community that they are part of an elite group that is publicly recognized for their skill in providing the highest-level care. Eligible clinicians must abstract data from the charts of diabetes patients (25 patients for a single applicant) and submit this information to NCQA for review. NCQA is an independent, not for profit organization dedicated to health related programs.

In 2016 and 2017, D Magazine once again named Dr. Carlson as one of the Best Doctors in Dallas.

BTE Asthma Care RecognitionDr. Carlson also received the Bridges to Excellence Award for Cardiac Care in 2014 and again in 2016. He also received the Bridges to Excellence Asthma Care Recognition in 2013 and 2016.

An avid history buff, Carlson loves collecting antiques, rare books, plus old 8 and 16mm movies. Not to mention, staying busy with a wonderful family during his spare time.

Dr. Carlson was proud to add a new Physician Assistant to his staff in 2015. Josanne attended graduated from Bryan Adams High School in Dallas then went to the University of Texas at Dallas, completing her Bachelor of Science in Biology with a minor in mathematics. She next attended Lock Haven University in Pennsylvania for Physician Assistant Studies before returning to Dallas to as a certified Physician’s Assistant.

  Josanne Howard’s interest in medicine began with a love of
nature in one of the world’s most picturesque isles.

Josanne Howard was born and raised in the beautiful Caribbean Republic of Trinidad and Tobago, tropical islands first sighted by Columbus in 1498 which eventually became British in 1814.

Trinidad and Tobago are two islands that make up the Republic, and each one is a veritable paradise. Tobago inspired the book Robinson Crusoe and was the location chosen by Walt Disney for the 1959 movie, Swiss Family Robinson.

Filming locations included some of Josanne’s old stomping grounds — Richmond Bay (the Robinson’s beach), Mount Irvine Bay (the Pirate’s beach), and the Craig Hall Waterfalls. The famed Swiss Family tree house was constructed in a 200-foot tall saman tree that still stands today in Goldsborough Bay.

Prior to coming to BestCare, Josanne practiced in an Emergency Medicine and Urgent Care setting so she is quite accustomed to helping patients of all ages, and dealing with the full range of everyday accidents, illnesses and ailments. Her warm, intelligent personality is instantly likable and her broad medical knowledge is a wonderful addition to the BestCare team. We are very proud to have her.

She is excited to be part of the BestCare team and looks forward to meeting you.
