About DuPage Medical Group

DuPage Med­ical Group (DMG) was formed in 1999 when three health­care groups serv­ing the west­ern sub­urbs of Chica­go since the 1960s joined togeth­er. Today, DMG has grown into the largest and most suc­cess­ful inde­pen­dent mul­ti-spe­cial­ty physi­cian groups in Illinois.

This suc­cess is large­ly based on the informed direc­tion it receives through a physi­cian-gov­erned board. DMG is led by expe­ri­enced physi­cians who con­tin­u­al­ly seek inno­va­tions through a mod­el of QEA: Qual­i­ty, Effi­cien­cy and Access.

Man­ag­ing such a proac­tive mod­el of med­i­cine allows DMG to pro­vide qual­i­ty care, con­struct the most advanced facil­i­ties and imple­ment the lat­est tech­nol­o­gy. Through secure access of an elec­tron­ic health record and our patient por­tal, MyChart, our physi­cians and patients stay close­ly con­nect­ed on the care that forms the big­ger pic­ture of each patient’s health. DMG pro­motes strong col­lab­o­ra­tion among its med­ical staff and solic­its help­ful feed­back from patients. Strong admin­is­tra­tive sup­port cre­ates sta­bil­i­ty for DMG physi­cians, empow­er­ing them to help dri­ve the group forward.

The end result is a tight-knit physi­cian group that sets the indus­try stan­dard and keeps ahead of the curve in the ever-chang­ing field of healthcare.

Mis­sion & Vision


The mis­sion of DuPage Med­ical Group is to enhance the phys­i­cal well being of the patients we serve by con­tin­u­ing to pro­vide the high­est qual­i­ty med­ical care available.


To accom­plish this mis­sion, DuPage Med­ical Group will always pro­vide a com­pre­hen­sive array of health­care ser­vices for our patients, uti­liz­ing lead­ing-edge tech­nol­o­gy and tech­niques. Our med­ical team and sup­port staff will work togeth­er as a close-knit team. In turn, this col­lab­o­ra­tive cul­ture will allow us to con­tin­u­al­ly attract the high­est qual­i­ty physi­cians and staff mem­bers. And by pre­serv­ing the physician’s lead­er­ship role in direct­ing our progress, DMG will ensure the most effi­cient, pro­gres­sive care possible.

The areas that we serve are also the places we call home. Our patients are our friends, fam­i­ly and neigh­bors. DuPage Med­ical Group will con­tin­ue to work active­ly in sup­port of these com­mu­ni­ties through vol­un­teer ser­vice and char­i­ta­ble giving.


DuPage Med­ical Group’s approach to ser­vice excel­lence is based on the fol­low­ing C.A.R.E. val­ues in our dai­ly prac­tice. These apply to inter­ac­tions with every­one we view as our cus­tomers: patients, staff, physi­cians, ven­dors and the greater community.


Gen­uine health­care address­es the needs of the patients and providers alike. The empa­thy that we show towards our cus­tomers begins with active lis­ten­ing. We then respond with action that we believe will pro­vide the best solu­tion. By demon­strat­ing gen­uine inter­est in the cus­tomer and meet­ing their needs, we build the foun­da­tion for DuPage Med­ical Group as a whole. 


DuPage Med­ical Group pro­motes a cul­ture of respon­si­bil­i­ty through respon­sive­ness and fol­low-through. Our abil­i­ty to pro­vide the high­est lev­el of care affords us the con­fi­dence to stand by our ser­vice for each cus­tomer. Accu­ra­cy is of the utmost impor­tance. The col­lab­o­ra­tive nature of our work helps us elim­i­nate mis­takes and make the most edu­cat­ed deci­sions possible. 


Sen­si­tiv­i­ty applies to much more than the phys­i­cal symp­toms of health­care. We pro­mote respect through con­sid­er­a­tion of each customer’s unique view­points and emo­tions. This cul­ture allows us to fos­ter a pos­i­tive envi­ron­ment to address impor­tant health­care needs. If our cus­tomers under­stand that they can trust us with their per­son­al feel­ings as well as their health con­cerns, we will be able to build rela­tion­ships that offer a life­time of care. 


We are com­mit­ted to going above and beyond expec­ta­tions for all cus­tomers at DuPage Med­ical Group. Our goal is to cre­ate a pos­i­tive expe­ri­ence that pro­vides reas­sur­ance and results. We offer pro­fes­sion­al ser­vice and advanced tech­nol­o­gy, all with­in a com­pas­sion­ate set­ting. And by con­tin­u­ous­ly tak­ing the ini­tia­tive to dis­cov­er new inno­va­tions, we give our cus­tomers a sense of secu­ri­ty in know­ing that they are in the most capa­ble hands.


The His­to­ry of DuPage Med­ical Group – Supe­ri­or Health Care and Innovation

DuPage Med­ical Group began 50 years ago as the brain­child of Dr. Robert McCray, a local sur­geon and health care vision­ary. Dr. McCray’s advance­ments helped rede­fine the physi­cian prac­tice in DuPage Coun­ty into the kind of per­son­al­ized, lead­ing-edge health care that until then was rarely avail­able out­side the uni­ver­si­ty med­ical or research cen­ter settings.

The For­ma­tion

In the ear­ly 1960s, Dr. McCray was still new to med­i­cine as a pri­vate-prac­tice sur­geon in Glen Ellyn, Ill., when he began re-imag­in­ing the physi­cian prac­tice as a way to give local patients access to advanced care spe­cial­ists and relat­ed med­ical ser­vices all under one roof. A rev­o­lu­tion­ary idea at a time when only 11 physi­cians prac­ticed in Glen Ellyn with few med­ical spe­cial­ists, Dr. McCray antic­i­pat­ed many aspects of group prac­tice now con­sid­ered commonplace.

Dr. McCray vis­it­ed 35 clin­ics across the coun­try, includ­ing Minnesota’s pres­ti­gious Mayo Clin­ic, exam­in­ing spe­cif­ic ele­ments that made group prac­tices suc­cess­ful. He teamed with sev­er­al local physi­cians – fel­low sur­geon and part­ner Dr. Glen Asselmeier, internists Drs. Joe Crum­rine, Fred Kuharich and James Erlen­born and pedi­a­tri­cians Drs. James Ver­coe and William Kin­dra­chuk. Dr. Gary Chris­tensen joined the team a short time lat­er after com­plet­ing a res­i­den­cy in obstet­rics and gynecology.

The group broke ground in August 1963 on a 12,000-square-foot build­ing and agreed on call­ing itself the Glen Ellyn Clin­ic, part­ly in homage to the Mayo Clinic.

Built with Innovation

The Glen Ellyn Clin­ic opened its doors on Sep­tem­ber 1, 1964, with eight physi­cians, 15 nurs­es and a staff of lab tech­ni­cians and admin­is­tra­tive per­son­nel. The clin­ic offered a host of inno­va­tions that were ground­break­ing at the time – a lab­o­ra­to­ry, X‑ray ser­vices and a phar­ma­cy, all onsite. The clin­ic offered evening hours, around-the-clock pedi­atric care and an urgent care depart­ment. For the first time, DuPage Coun­ty patients had access to a full range of spe­cial­ty health care – surgery, inter­nal med­i­cine, obstet­rics and gyne­col­o­gy, pedi­atrics and ancil­lary ser­vices – in one location. 

The clin­ic embraced admin­is­tra­tive inno­va­tions as well. Physi­cians com­bined their nurs­ing and office staffs, med­ical records and billing func­tions. Accounts receiv­able were pooled and a bonus struc­ture imple­ment­ed based on per­for­mance and clin­ic prof­itabil­i­ty. The founders also ensured part­ner­ships would be avail­able to younger physicians. 

After it’s first year of oper­a­tion, the clin­ic was see­ing 300 new patients a month. By 1970, the part­ner­ship had grown to 25 physi­cians, while office and lab space was added with a 24,000-square-foot clin­ic expansion.

Suc­cess and Growth

The clinic’s patient pop­u­la­tion and staff con­tin­ued expand­ing in the ear­ly 1970s. Two new office build­ings were built to accom­mo­date the many new med­ical spe­cial­ists who were join­ing. New physi­cians saw Glen Ellyn Clin­ic as an oppor­tu­ni­ty to prac­tice in the com­pa­ny of estab­lished col­leagues. Mean­while, the clin­ic intro­duced a range of spe­cial­ties to the West­ern Sub­urbs, includ­ing tho­racic surgery, neu­ro­surgery, car­diac surgery, gas­troen­terol­o­gy, inva­sive car­di­ol­o­gy and neonatology.

The clin­ic con­tin­ued expand­ing in the 1980s, adding 38,000 square feet of office and lab space to accom­mo­date physi­cians in 16 spe­cial­ties and sub-spe­cial­ties. Clin­ic offices were opened in Bloom­ing­dale and Naperville with a full range of ser­vices. By the end of the decade, the Glen Ellyn Clin­ic was one of the city’s biggest employ­ers – 80 physi­cians and a staff of 480 han­dling 300,000 annu­al patient vis­its. It also owned one of the largest clin­ic oper­at­ed labs in Illi­nois, annu­al­ly per­form­ing more than 100,000 tests onsite and 25,000 more offsite.

Change and Transition

The 1990s saw sig­nif­i­cant changes as sev­er­al found­ing clin­ic part­ners began retir­ing. In addi­tion, advances in med­ical and infor­ma­tion tech­nol­o­gy required sig­nif­i­cant finan­cial invest­ment to keep pace with the indus­try. Beyond that, the emer­gence of man­aged care and the result­ing changes in reim­burse­ment meth­ods called for new oper­a­tional strate­gies. In the late 1990s, the clin­ic became part of the country’s largest physi­cian man­age­ment com­pa­ny in an effort to ensure the finan­cial strength it need­ed to con­tin­ue growing. 

The new arrange­ment didn’t mean an end to the chal­lenges, how­ev­er. As man­aged care gained ground in the 1990s, physi­cian groups across the coun­try expe­ri­enced increas­ing pres­sures, includ­ing two oth­ers in DuPage Coun­ty that would fig­ure promi­nent­ly in the Glen Ellyn Clinic’s future – Mid-Amer­i­ca Health Part­ners and Wheaton Med­ical Clinic. 

Formed in 1964, Wheaton Med­ical Clin­ic includ­ed 25 physi­cians and had recent­ly affil­i­at­ed itself with a major health insur­er. With 50 pri­ma­ry care physi­cians, Mid-Amer­i­ca Health Part­ners had formed in 1995 as a physi­cian-led inde­pen­dent prac­tice group. After Wheaton Med­ical Clin­ic merged with the Glen Ellyn Clin­ic in 1997, Mid-Amer­i­ca joined the fol­low­ing year. Short­ly after, physi­cians from all three began efforts to return the com­bined clin­ic to the pri­vate physi­cian group-prac­tice mod­el under local control. 

The result was DuPage Med­ical Group formed in 1999.

Present-Day Com­mit­ment

DuPage Med­ical Group is now the state’s lead­ing mul­ti-spe­cial­ty group prac­tice and still com­mit­ted to supe­ri­or care and inno­va­tion, with a lead­er­ship struc­ture designed to main­tain bal­ance between pri­ma­ry and spe­cial­ty care. With more than 700 pri­ma­ry care and spe­cial­ty physi­cians in more than 100 loca­tions, DuPage Med­ical Group han­dles upwards of 2 mil­lion patient vis­its annu­al­ly, treat­ing about a third of DuPage County’s population. 

Today, DuPage Med­ical Group is expe­ri­enc­ing unprece­dent­ed growth and expan­sion into neigh­bor­ing coun­ties, as the orga­ni­za­tion con­tin­u­ous­ly strives to meet the pop­u­la­tion growth and move­ment of patients into sur­round­ing areas. Car­ry­ing on the lega­cy of Dr. McCray and his co-founders, DuPage Med­ical Group is focused on pro­vid­ing the West­ern Sub­urbs with access to the finest health care avail­able and oper­at­ing on the prin­ci­pal that physi­cians make the best deci­sions for patient care. 

The Road Ahead

With recent­ly enact­ed changes in nation­al health care pol­i­cy, uncer­tain­ty in the indus­try is like­ly to linger for the next sev­er­al years. DuPage Med­ical Group will stay pre­pared by con­tin­u­ing to attract the most tal­ent­ed physi­cians, nurs­es and admin­is­tra­tive staff. Along the way, we’ll nev­er for­get our founders’ ded­i­ca­tion to the patients and neigh­bor­hoods we serve.
